... Write Disable Function when Power Supply Voltage is Low The S-93A46A/56A/66A 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 ...

... S-93A46A/56A/66A Function to Protect Against Write due to Erroneous Instruction Recognition The S-93A46A/56A/66A 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 ...

... I/O Pins 1. Connection of Input Pins All the input pins of the S-93A46A/56A/66A employ a CMOS structure, so design the equipment so that high impedance will not be input while the S-93A46A/56A/66A is operating. Especially, deselect the CS input (a low level) when turning on/off power and during standby. When the CS pin is deselected (a low level), incorrect data writing will not occur ...

... TEST 2.2 Output Pin 3. Input Pin Noise Elimination Time The S-93A46A/56A/66A 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 ...
