FUNCTIONAL DESCRIPTION AS58C1001 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. AUTOMATIC PAGE WRITE The Page Write feature allows 1 to 128 Bytes of data to be written into the EEPROM in a single cycle and allows the undefined data within 128 Bytes to be written corresponding to the undefined address (A0 to A6). Loading the first Byte of data, the data load window of 30µs opens for the second. In the same manner each additional Byte of data can be loaded within 30µs. In case CE\ and WE\ are kept high for 100µs after data input, the EEPROM enters erase and write automatically and only the input data can be written into the EEPROM. In Page mode the data can be written and accessed 104 times per page, and in Byte mode 103 times per Byte. End Of Life DATA\ POLLING Data\ Polling allows the status of the EEPROM to be determined. If the EEPROM is set to Read mode during a Write cycle, and inversion of the last Byte of data to be loaded outputs from I/O, to indicate that the EEPROM is performing a Write operation. WRITE PROTECTION (1) Noise protection: Noise on a write cycle will not act as a trigger with a WE\ pulse of less than 20ns. (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 104 cycles (1% cumulative failure rate) and the data retention time is more than 10 years when a device is programmed less than 104 cycles.

(EXAMPLE) Vcc End Of Life RES\ *unprogrammable *unprogrammable FUNCTIONAL DESCRIPTION (continued) Write Address DATA PROTECTION (continued) 2. Data protection at Vcc on/off. When RES\ is low, the EEPROM cannot be erased and programmed. Therefore, data can be protected by keeping RES\ low when Vcc is switched. RES\ should be high during programming because it does not provide a latch function. When Vcc is turned on or off, noise on the control pins generated by external circuits (CPU, etc.) may turn the EEPROM to programming mode by mistake. To prevent this unintentional programming, the EEPROM must be kept in an unprogrammable, standby or readout state by using a CPU reset signal to RES\ pin. In addition, when RES\ is kept high at Vcc on/off timing, the input level of control pins (CE\, OE\, WE\) must be held as CE\=Vcc or OE\=LOW or WE\=Vcc level. 5555 AA 2AAA 55 5555 A0 The Software data protection mode can be cancelled by inputting the following 6 Bytes. This changes the AS58C1001 to the Non-Protection mode, for normal operation. 3. Software Data Protection To protect against unintentional programming caused by noise generated by external circuits, AS58C1001 has a Software data protection function. To initate Software data protection mode, 3 bytes of data must be input, followed by a dummy write cycle of any address and any data byte. This exact sequence switches the device into protection mode.
