125°C OPERATION 3-WIRE SERIAL E2PROM FOR AUTOMOTIVE S-93A86A Rev.6.1_00 Seiko Instruments Inc. 10  Operation All instructions are executed by inpu tting DI in synchronization with the rising edge of SK after CS goes high. An instruction set is input in the order of start bit, instruction, address, and data. Instruction input finishes when CS goes low. A lo w level must be input to CS between commands during t CDS. While a low level is being input to CS, the S-93A 86A is in standby mode, so the SK and DI inputs are invalid and no instructions are allowed.  Start Bit A start bit is recognized when the DI pin goes high at the rise of SK after CS goes high. After CS goes high, a start bit is not recognized even if the SK pulse is input as long as the DI pin is low. 1. Dummy clock SK clocks input while the DI pin is lo w before a start bit is input are called dummy clocks. Dummy clocks are effective when aligning the number of instruction sets (clocks) sent by the CPU with those required for serial memory operation. For example, when the CP U instruction set is 16 bits, the num ber of instruction set clocks can be adjusted by inserting the 3-bit dummy clock in S-93A86A. 2. Start bit input failure

• When the output status of the DO pin is high during the verify period after a write operation, if a high level is input to the DI pin at the rising edge of SK, the S-93A86A recognize s that a start bit has been input. To prevent this failure, input a low level to the DI pin during the verify operation period (Refer to “4. 1 Verify operation ”).
• When a 3-wire interface is configur ed by connecting the DI input pin and DO output pin, a period in which the data output from the CPU and the serial me mory collide may be generated, preventing successful input of the start bit. Take the measures described in “ 3-Wire Interface (Direct Connection between DI and DO)”.

125°C OPERATION 3-WIRE SERIAL E2PROM FOR AUTOMOTIVE Rev.6.1_00 S-93A86A Seiko Instruments Inc. 11 3. Reading (READ) The READ instruction reads data from a specified address. After CS has gone high, input an instruction in the order of the start bit, read instruction, and address. Since the last input address (A0) has been latched, the output status of the DO pin changes fr om high impedance (High-Z) to low, which is held until the next rise of SK. 16-bit data starts to be output in synchronization with the next rise of SK. 3. 1 Sequential read After the 16-bit data at the specif ied address has been output, inputting SK while CS is high automatically increments the address, and causes the 16-bit data at the next address to be out put sequentially. The above method makes it possible to read the data in t he whole memory space. The last address (A 9  A 1 A0 = 1  1 1) rolls over to the top address (A9  A 1 A0 = 0  0 0).

Writing (WRITE, ERASE, WRAL, ERAL) A write operation includes four write instructions: data wr ite (WRITE), data erase (ER ASE), chip write (WRAL), and chip erase (ERAL). A write instruction (WRITE, ERASE, WRAL, ERAL) starts a write operation to the memory cell when a low level is input to CS after a specified number of clocks have been input. The SK and DI inputs are invalid during the write period, so do not input an instruction. Input an instruction while the output status of the DO pin is high or high impedance (High-Z). A write operation is valid only in program enable mode (refer to “ 5. Write enable (EWEN) and write disable (EWDS)”). 4. 1 Verify operation A write operation executed by any instruction is completed within 5 ms (write time t PR: typically 2 ms), so if the completion of the write operation is recognized, the write cycle can be mi nimized. A sequential operation to confirm the status of a write operation is called a verify operation. (1) Operation After the write operation has started (CS = low), the stat us of the write operation can be verified by confirming the output status of the DO pin by inputting a high level to CS again. This sequence is called a verify operation, and the period t hat a high level is input to the CS pin a fter the write operation has started is called the verify operation period. The relationship between the output st atus of the DO pin and the write operation duri ng the verify operation period is as follows.

• DO pin = low: Writing in progress (busy)
• DO pin = high: Writing completed (ready) (2) Operation example There are two methods to perform a verify operation: Wa iting for a change in the output status of the DO pin while keeping CS high, or suspending the verify oper ation (CS = low) once and then performing it again to verify the output status of the DO pin. The latter method allows the CPU to perform other processing during the wait period, allowing an efficient system to be designed. Caution 1. Input a low level to the DI pin during a verify operation. 2. If a high level is input to the DI pin at the rise of SK when the output status of the DO pin is high, the S-93A86A latches the instruction assuming that a start bit has been input. In this case, note that the DO pin immediately enters a high-impedance (High-Z) state.

Write enable (EWEN) and write disable (EWDS) The EWEN instruction is an instructi on that enables a write operat ion. The status in wh ich a write operation is enabled is called the program enable mode. The EWDS instruction is an instruction that disables a write oper ation. The status in which a write operation is disabled is called the program disable mode. After CS goes high, input an instructi on in the order of the start bit, EW EN or EWDS instruction, and address (optional). Each mode becomes valid by inputting a low le vel to CS after the last address (optional) has been input.

125°C OPERATION 3-WIRE SERIAL E2PROM FOR AUTOMOTIVE S-93A86A Rev.6.1_00 Seiko Instruments Inc. 16  Write Protect Function during the Low Power Supply Voltage The S-93A86A provides a built-in detecto r to detect a low power supply voltage and disable writing. When the power supply voltage is low or at power applic ation, the write instruct ions (WRITE, ERASE, WRAL, ERAL) are cancelled, and the write disable state (EWDS) is automatically set. The detection voltage is 1.20 V typ., the release voltage is 1.35 V typ., and there is a hysteresis of about 0.15 V (Refer to Figure 12). Therefore, when a write operation is performed after the power supply voltage has dr opped and then risen again up to the level at wh ich writing is possible, a write enable instruction (EWEN) must be sent before a write instruction (WRITE, ERASE, WRAL, ERAL) is executed. When the power supply voltage drops during a write operation, t he data being written to an addre ss at that time is not guaranteed. Release voltage (+VDET) 1.35 V typ.

Instructions are cancelled if a clock pulse whose count other t han the one specified for each write instruction (WRITE, ERASE, WRAL, ERAL) is detected. <Example> Erroneous Recognition of Program Disable Instruction (EWDS) as Erase Instruction (ERASE) Input EWDS instruction Erroneous recognition as ERASE instruction due to noise pulse Noise pulse Example of S-93A86A In products that do not incorporate a cloc k pulse monitoring circuit, FFFF is mistakenly written to address 00h. However the S-93A86A detects the over count and cancels the instruction without performing a write operation.

125°C OPERATION 3-WIRE SERIAL E2PROM FOR AUTOMOTIVE S-93A86A Rev.6.1_00 Seiko Instruments Inc. 18  3-Wire Interface (Direct Connection between DI and DO) There are two types of serial interface configurations: a 4-wire interface conf igured using the CS, SK, DI, and DO pins, and a 3-wire interface that connects the DI input pin and DO output pin. When the 3-wire interface is employed, a period in which the dat a output from the CPU and the data output from the serial memory collide may occur, causing a malfunction. To prevent such a malfunction, connect the DI and DO pins of the S-93A86A via a resistor (10 k Ω to 100 k Ω) so that the data output from the CPU takes precedence in being input to the DI pin (Refer to “Figure 14 Connection of 3-Wire Interface ”). CPU S-93A86A R: 10 kΩ ∼ 100 kΩ DI DO SIO Figure 14 Connection of 3-Wire Interface  Input Pin and Output Pin 1. Connection of input pin All the input pins of the S-93A86A employ a CMOS structure, so des ign the equipment so that high impedance will not be input while the S-93A86A is operating. Especially, deselect the CS input (a low level) when turning on/off power and during standby. When the CS pi n is deselected (a low level), inco rrect data writing will not occur. Connect the CS pin to GND via a resistor (10 k Ω to 100 k Ω pull-down resistor). To prevent malfunction, it is recommended to use equivalent pull-down resistors for pins other than the CS pin. 2. Equivalent circuit of input pin and output pin The following shows the equivalent circuits of input pins of the S-93A86A. None of the input pins incorporate pull-up and pull-down elements, so special care must be taken when designing to prevent a floating status. Output pins are high-level/low-leve l/high-impedance tri-state out puts. The TEST pin is disconnected from the internal circuit by a switching transistor during normal operation. As long as the absolute maximum rating is satisfied, the TEST pin and internal circuit will never be connected.
