Description
The AT27LV020A is a high performance, low power, low voltage 2,097,152 bit one-
time programmable read only memory (OTP EPROM) organized as 256K by 8 bits. It
requires only one supply in the range of 3.0 to 3.6V in normal read mode operation,
making it ideal for fast, portable systems using battery power.

Notes:
1. Timing measurement references are 0.8V and 2.0V.
Input AC drive levels are 0.45V and 2.4V, unless oth-
erwise specififed.
2. OE may be delayed up to tCE - tOE after the falling
edge of CE without impact on tCE.
3. OE may be delayed up to tACC - tOE after the address
is valid without impact on tACC.
4. This parameter is only sampled and is not 100%
tested.
5. Output float is defined as the point when data is no
longer driven.
