... 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 . While a low level is being input to CS, the S-93A86A is in standby mode, so the SK and DI inputs are CDS invalid and no instructions are allowed. ...

Input a low level to the DI pin during a verify operation 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 (Hi-Z) state ...

... CMOS SERIAL E PROM S-93A86A 4.4 Writing to Chip (WRAL) To write the same 16-bit data to the entire memory address space, change CS to high, and then input the WRAL instruction, an address, and 16-bit data following the start bit. Any address can be input. The write operation starts when CS goes low. There is no need to set the data to 1 before writing. ...

... Write Disable Function when Power Supply Voltage is Low The S-93A86A provides a built-in detector to detect a low power supply voltage and disable writing. When the 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 automatically set. The detection voltage is 1.20 V typ ...

... S-93A86A Function to Protect Against Write due to Erroneous Instruction Recognition The S-93A86A provides a built-in clock pulse monitoring circuit which is used to prevent an erroneous write operation by canceling write instructions (WRITE, ERASE, WRAL, and ERAL) recognized erroneously due to an erroneous clock count caused by the application of noise pulses or double counting of clocks. ...

... 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 that the data output from the CPU takes precedence in being input to the DI pin (Refer to “ Figure 12 Connection of 3-Wire Interface ”). ...

... TEST 2.2 Output Pin 3. Input Pin Noise Elimination Time The S-93A86A includes 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 less can be eliminated. Note, therefore, that noise with a pulse width of more than 20 ns will be recognized as a pulse if the ...
