Description
The AT29LV1024 is a 3-volt only in-system Flash programmable and erasable read
only memory (PEROM). Its 1 megabit of memory is organized as 65,536 words by 16
bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device
offers access times to 150 ns with power dissipation of just 54 mW. When the device
is deselected, the CMOS standby current is less than 50 µA. The device endurance is

Notes:
1. CE may be delayed up to tACC - tCE after the address transition without impact on tACC.
2. OE may be delayed up to tCE - tOE after the falling edge of CE without impact on tCE or by tACC - tOE after an address change
without impact on tACC.
3. tDF is specified from OE or CE whichever occurs first (CL = 5 pF).
4. This parameter is characterized and is not 100% tested.
