(2) write inhibit: holding oe\ low, we\ high or ce\ high, inhibits a write cycle during power on/off. we\ and ce\ pin operation during a write cycle, addresses are latched by the falling edge of we\ or ce\, and data is latched by the rising edge of we\ or ce\. write/erase endurance and data retention the endurance with page programming is 10 4 cycles (1% cumulative failure rate) and the data retention time is more than 10 years when a device is programmed less than 10 4 cycles. data protection to protect the data during operation and power on/off, the AS58C1001 has: 1. data protection against noise on control pins (ce\, oe\, we\) during operation. during readout or standby, noise on the control pins may act as a trigger and turn the eeprom to programming mode by mistake. to prevent this phenomenon, the AS58C1001 has a noise cancellation function that cuts noise if its width is 20ns or less in programming mode. be careful not to allow noise of a width of more than 20ns on the control pins.
