W25D10, W25D20, W25D40, W25D80 - 4 - 1. GENERAL DESCRIPTION The W25D10 (1M-bit), W25D20 (2M-bit), W25D40 (4M-bit) and W25D80 (8M-bit) Serial Flash memories provide a storage solution for systems wi th limited space, pins and power. The 25X series offers flexibility and performance well beyond ordinary Serial Flash devices. They are ideal for code download applications as well as storing voice, text and data. The devices operate on a single 2.7V to 3.6V power supply with current consumption as low as 5mA active and 1µA for power-down. All devices are offered in space-saving packages. The W25D10/20/40/80 array is organized into 512/1024/2048/4096 programmable pages of 256-bytes each. Up to 256 bytes can be programmed at a time using the Page Program instruction. Pages can be erased in groups of 16 (sector erase), groups of 256 (block erase) or the entire chip (chip erase). The W25D10/20/40/80 has 32/64/128/256 erasable sectors and 2/4/8/16 erasable blocks respectively. The small 4KB sectors allow for greater flexibilit y in applications that require data and parameter storage. (See figure 2.) The W25D10/20/40/80 supports the standard Serial Peripheral Interface (SPI), and a high performance dual output SPI using four pins: Serial Clock, Chip Select, Serial Data I/O and Serial Data Out. SPI clock frequencies of up to 75MHz ar e supported allowing equivalent clock rates of 150MHz when using the Fast Read Dual Output inst ruction. These transfer rates are comparable to those of 8 and 16-bit Parallel Flash memories. A Hold pin, Write Protect pin and programmable wr ite protect, with top or bottom array control features, provide further control flexibility. Additionally, the devic e supports JEDEC standard manufacturer and device identification. 2. FEATURES

7.1 Package Types

At the time this datasheet was published not all package types had been finalized. Contact Winbond to confirm availability of these packages before designing to this specification. The W25D10, W25D20 and W25D40 are offered in an 8-pin plastic 150-mil width SOIC (package code SN) as shown in figure 1a. The W25D40 and W25D80 is offered in an 8-pin plastic 208-mil width SOIC (package code SS) as shown in figure 1b. All parts will be offered in 6x5-mm WSON (package code ZP) and 300-mil DIP (package code DA). Package diagrams and dimensions are illustrated at the end of this datasheet.

7.2 Chip Select (/CS)

The SPI Chip Select (/CS) pin enables and disables device operation. When /CS is high the device is deselected and the Serial Data Output (DO) pin is at high impedance. When deselected, the devices power consumption will be at standby levels unless an in ternal erase, program or status register cycle is in progress. When /CS is brought low the device will be select ed, power consumption will increase to active levels and instructions can be written to and data read from the device. After power-up, /CS must transition from high to low before a new inst ruction will be accepted. The /CS input must track the VCC supply level at power-up (see “Write Pr otection” and figure 20). If needed a pull-up resister on /CS can be used to accomplish this.

7.3 Serial Data Output (DO)

The SPI Serial Data Output (DO) pin provides a means for data and status to be serially read from (shifted out of) the device. Data is shifted out on the falling edge of the Serial Clock (CLK) input pin.

7.4 Write Protect (/WP)

The Write Protect (/WP) pin can be used to prevent the Status Register from being written. Used in conjunction with the Status Register’s Block Pr otect (BP2, BP1, and BP0) bits and Status Register Protect (SRP) bits, a portion or the entire memory array can be hardware protected. The /WP pin is active low.

7.5 HOLD (/HOLD)

The /HOLD pin allows the device to be paused while it is actively selected. When /HOLD is brought low, while /CS is low, the DO pin will be at high im pedance and signals on the DIO and CLK pins will be ignored (don’t care). When /HOLD is brought high, device operation can resume. The /HOLD function can be useful when multiple devices are sharing the same SPI signals. (“See Hold function”)

7.6 Serial Clock (CLK)

The SPI Serial Clock Input (CLK) pin provides t he timing for serial input and output operations. ("See SPI "Operations")

7.7 Serial Data Input / Output (DIO)

The SPI Serial Data Input/Output (DIO) pin provi des a means for instructions, addresses and data to be serially written to (shifted in to) the device. Data is latched on the rising edge of the Serial Clock (CLK) input pin. The DIO pin is also used as an out put when the Fast Read Dual Output instruction is executed.

9.1 SPI OPERATIONS

9.1.1 SPI Modes

The W25D10/20/40/80 is accessed through an SPI compat ible bus consisting of four signals: Serial Clock (CLK), Chip Select (/CS), Serial Data Input/Output (DIO) and Serial Data Output (DO). Both SPI bus operation Modes 0 (0,0) and 3 (1,1) are suppor ted. The primary difference between Mode 0 and Mode 3 concerns the normal state of the CLK signal when the SPI bus master is in standby and data is not being transferred to the Serial Flash. For Mode 0 the CLK signal is normally low. For Mode 3 the CLK signal is normally high. In either case data input on the DIO pin is sampled on the rising edge of the CLK. Data on the DO and DIO pins are clocked out on the falling edge of CLK.

9.1.2 Dual Output SPI

The W25D10/20/40/80 supports Dual output operation when using the "Fast Read with Dual Output" (3B hex) instruction. This feature allows data to be transferred from t he Serial Flash memory at twice the rate possible with the standard SPI. This inst ruction is ideal for quickly downloading code from Flash to RAM upon power-up (code-shadowing) or for applications that cache code-segments to RAM for execution. The Dual output f eature simply allows the SPI input pin to also serve as an output during this instruction. All other operations use the standard SPI interface with single output signal.

9.1.3 Hold Function

The /HOLD signal allows the W25D10/20/40/80 operati on to be paused while it is actively selected (when /CS is low). The /HOLD function may be useful in cases where the SPI data and clock signals are shared with other devices. For example, consider if the page buffer was only partially written when a priority interrupt requires use of the SPI bus. In this case the /HOLD function can save the state of the instruction and the data in the buffer so progra mming can resume where it left off once the bus is available again. To initiate a /HOLD condition, the device must be selected with /CS low. A /HOLD condition will activate on the falling edge of the /HOLD signal if t he CLK signal is already low. If the CLK is not already low the /HOLD condition will activate after the next falling edge of CLK. The /HOLD condition will terminate on the rising edge of the /HOLD signal if the CLK signal is already low. If the CLK is not already low the /HOLD condition will terminate after the next falling edge of CLK. During a /HOLD condition, the Serial Data Output (D O) is high impedance, and Serial Data Input/Output (DIO) and Serial Clock (CLK) are ignor ed. The Chip Select (/CS) signal should be kept active (low) for the full duration of the /HOLD operation to avoid resetting the internal logic state of the device.

9.2 WRITE PROTECTION

Applications that use non-volatile memory must ta ke into consideration the possibility of noise and other adverse system conditions that may compromi se data integrity. To address this concern the W25D10/20/40/80 provides several means to protect data from inadvertent writes.

9.2.1 Write Protect Features

  • Device resets when VCC is below threshold.
  • Time delay write disable after Power-up.
  • Write enable/disable instructions.
  • Automatic write disable after program and erase.
  • Software write protection using Status Register.
  • Hardware write protection using Status Register and /WP pin.
  • Write Protection using Power-down instruction. Upon power-up or at power-down the W25D10/20/40/80 will maintain a reset condition while VCC is below the threshold value of V WI, (See Power-up Timing and Voltage Levels and Figure 20). While reset, all operations are disabled and no instructi ons are recognized. During power-up and after the VCC voltage exceeds V WI, all program and erase related instructions are further disabled for a time delay of tPUW. This includes the Write Enable, Page Program , Sector Erase, Block Erase, Chip Erase and the Write Status Register instructions. Note t hat the chip select pin (/CS) must track the VCC supply level at power-up until the VCC-min level and t VSL time delay is reached. If needed a pull-up resister on /CS can be used to accomplish this. After power-up the device is automatically placed in a write-disabled state with the Status Register Write Enable Latch (WEL) set to a 0. A Write Enable instruction must be issued before a Page Program, Sector Erase, Chip Erase or Write Stat us Register instruction will be accepted. After completing a program, erase or write instruction the Write Enable Latch (WE L) is automatically cleared to a write-disabled state of 0. Software controlled write protection is facilitated using the Write Status Register instruction and setting the Status Register Protect (SRP) and Block Pr otect (TB, BP2, BP1, and BP0) bits. These Status Register bits allow a portion or all of the memory to be configured as read only. Used in conjunction with the Write Protect (/WP) pin, changes to t he Status Register can be enabled or disabled under hardware control. See Status Register for further information. Additionally, the Power-down instruction offers an extra level of write protection as all instructions are ignored except for the Release Power-down instruction.

W25D10, W25D20, W25D40, W25D80 Publication Release Date: July 15, 2006 - 1 1 - P r e l i m i n a r y - R e v i s i o n A 10. CONTROL AND STATUS REGISTERS The Read Status Register instruction can be used to provide status on the av ailability of the Flash memory array, if the device is write enabled or dis abled, and the state of writ e protection. The Write Status Register instruction can be used to configure the devices write protection features. See Figure 3.

10.1 STATUS REGISTER

10.1.1 BUSY

BUSY is a read only bit in the status register (S0) t hat is set to a 1 state w hen the device is executing a Page Program, Sector Erase, Block Erase, Chip Er ase or Write Status Regi ster instruction. During this time the device will ignore further instructions except for the Read Status Register instruction (see tW, t PP, t SE, TBE , and t CE in AC Characteristics). When the progr am, erase or write status register instruction has completed, the BUSY bit will be clear ed to a 0 state indicating the device is ready for further instructions.

10.1.2 Write Enable Latch (WEL)

Write Enable Latch (WEL) is a read only bit in the status register (S1) that is set to a 1 after executing a Write Enable Instruction. The WE L status bit is cleared to a 0 w hen the device is write disabled. A write disable state occurs upon power-up or after any of the following instructions: Write Disable, Page Program, Sector Erase, Block Erase, Chip Erase and Write Status Register.

10.1.3 Block Protect Bits (BP2, BP1, BP0)

The Block Protect Bits (BP2, BP1, and BP0) are non-volatile read/write bits in the status register (S4, S3, and S2) that provide Write Protection control and status. Block Protect bits can be set using the Write Status Register Instruction (see t W in AC characteristics). All, none or a portion of the memory array can be protected from Program and Erase instru ctions (see Status Regi ster Memory Protection table). The factory default setting for the Block Protec tion Bits is 0, none of the array protected. The Block Protect bits can not be written to if the Status Register Protect (SRP) bit is set to 1 and the Write Protect (/WP) pin is low.

10.1.4 Top/Bottom Block Protect (TB)

The Top/Bottom bit (TB) controls if the Block Pr otect Bits (BP2, BP1, BP0 ) protect from the Top (TB=0) or the Bottom (TB=1) of the array as shown in the Status Register Memory Protection table. The TB bit is non-volatile and the factory default setti ng is TB=0. The TB bit can be set with the Write Status Register Instruction provided that the Write Enable instruction has been issued. The TB bit can not be written to if the Status Regi ster Protect (SRP) bit is set to 1 and the Write Protect (/WP) pin is low.

10.1.5 Reserved Bits

Status register bit location S6 is reserved for fu ture use. Current devices will read 0 for this bit location. It is recommended to mask out the reserved bi t when testing the Status Register. Doing this will ensure compatibility with future devices.

10.1.6 Status Register Protect (SRP)

/WP pin is high the Write Status Register instruction is allowed. Figure 3. Status Register Bit Locations

10.2 INSTRUCTIONS

The instruction set of the W25D 10/20/80/16 consists of fifteen basic instructions that are fully controlled through the SPI bus (see Instruction Set t able). Instructions are initiated with the falling edge of Chip Select (/CS). The firs t byte of data clocked into the DI O input provides the instruction code. Data on the DIO input is sampled on the rising edge of clock with most significant bit (MSB) first. Instructions vary in length from a single byte to several bytes and may be followed by address bytes, data bytes, dummy bytes (don’t care), and in some ca ses, a combination. Inst ructions are completed with the rising edge of edge /CS. Clock relative ti ming diagrams for each instruction are included in figures 4 through 19. All read instructions can be completed after any clocked bit. However, all instructions that Write, Program or Erase must complete on a byte boundary (CS driven high after a full 8-bits have been clocked) otherwise the instructi on will be terminated. This feature further protects the device from inadvertent writes . Additionally, while the memory is being programmed or erased, or when the Status Register is being written, all inst ructions except for Read Status Register will be ignored until the program or erase cycle has completed.
