FOR AUTOMOTIVE 105°C OPERATION 3-WIRE SERIAL E2PROM Rev.2.1_00 S-93C46B/56B/66B H Series Seiko Instruments Inc. 11  Operation All instructions are executed by inputting 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 low level must be input to CS between commands during t CDS. While a low level is being input to CS, the S-93C46B/56B/66B 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 ca lled dummy clocks. Dummy clocks are effective when aligning the number of in struction sets (clocks) sent by the CPU with those required for serial memory operation. For example, when a CPU instruction set is 16 bits, the number of instruction set clocks can be adjusted by inserting a 7-bit dummy clock for the S-93C46B and a 5-bit dummy clock for the S-93C56B/66B. 2. Start bit input failure

• When the output status of the DO pin is high during the veri fy period after a write operation, if a high level is input to the DI pin at the rising edge of SK, the S-93C46B/56B/66B recognizes 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 configured by connecting the DI input pin and DO output pin, a period in which the data output from the CPU and the serial memory collide may be gener ated, preventing succe ssful input of the start bit. Take the measures described in “  3-Wire Interface (Direct Connection between DI and DO)”.

FOR AUTOMOTIVE 105°C OPERATION 3-WIRE SERIAL E2PROM Rev.2.1_00 S-93C46B/56B/66B H Series Seiko Instruments Inc. 13 4. Writing (WRITE, ERASE, WRAL, ERAL) A write operation includes four write instructions: data write (WRITE), data erase (ERASE), 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 ar e 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 8 ms (write time t PR: typically 4 ms), so if the completion of the write operation is recognized, the wr ite cycle can be minimized. 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 status 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 that a high level is input to the CS pin after the write operation has started is called the verify operation period. The relationship between the output status of the DO pin and the write operation during 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: Waiting for a change in the output status of the DO pin while keeping CS high, or suspending the verify operation (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-93C46B/56B/66B 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.

When t he power supply voltage is low or at power application, the write instructions (WRITE, ERASE, WRAL, and ERAL) are cancelled, and the write disable state (EWDS) is about 0.3 V (refer to Figure 18). Therefore, when a write operation is performed after the power supply voltage has dropped and then risen again up to the level at which writing is possible, a write enable instruction (EWEN) must be sent before a write instruction (WRITE, ERASE, WRAL, or ERAL) is executed. When the power supply voltage drops during a write operation, the data being written to an address at that time is not guaranteed. Release voltage (+VDET) 2.05 V Typ.

Instructions are cancelled if a clock pulse more or less than specified number decided by each write operation (WRITE, ERASE, WRAL, or ERAL) is detected. <Example> Erroneous recognition of program disable instruction (EWDS) as erase instruction (ERASE) 1 3 4 5 6 7 2 8 9 CS SK DI Input EWDS instruction Erroneous recognition as ERASE instruction due to noise pulse 1 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 1 0 Noise pulse Example of S-93C46B In products that do not include a clock pulse monitoring circuit, FFFF is mistakenly written on address 00h. However the S-93C46B detects the overcount and cancels the instruction without performing a write operation. Figure 19 Example of Clock Pulse Monitoring Circuit Operation

FOR AUTOMOTIVE 105°C OPERATION 3-WIRE SERIAL E2PROM Rev.2.1_00 S-93C46B/56B/66B H Series Seiko Instruments Inc. 21  3-Wire Interface (Direct Connection between DI and DO) There are two types of serial interface configurations: a 4-wire interface configured 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 whic h the data 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-93C46B/56B/66B via a resistor (10 to 100 k Ω) so that the data output from the CPU takes precedence in being input to the DI pin (refer to “Figure 20 Connection of 3-Wire Interface ”). CPU DISIO DO S-93C46B/56B/66B R : 10 to 100 kΩ Figure 20 Connection of 3-Wire Interface  I/O Pin 1. Connection of input pins All the input pins of the S-93C46B/56B/66B employ a CMOS structure, so design the equipment so that high impedance will not be input while the S-93C 46B/56B/66B is operating. Especially, deselect the CS input (a low level) when turning on/off power and during standby. When t he CS pin is deselected (a low level), incorrect data writing will not occur. Connect the CS pin to GND via a resistor (10 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 and output pin The following shows the equivalent circuits of input pi ns of the S-93C46B/56B/66B. None of the input pins incorporate pull-up and pull-down elements, so special ca re must be taken when designing to prevent a floating status. Output pins are high-level/low-level/high-impedance tri-st ate outputs. 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.

Input pin noise elimination time The S-93C46B/56B/66B include a built-in low-pass filter to eliminate noise at the SK, DI, and CS pins. This means that if the supply voltage is 5.0 V (at room temperature), noise with a pulse width of 20 ns or less can be eliminated. Note, therefore, the noise with a pulse width of more than 20 ns will be recognized as a pulse if the voltage exceeds VIH/VIL.  Precaution
