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. The Input Timing Reference is 0.8V for VIL and 2.0V for VIH.
2. tOE and tDFP are characteristics of the device but must be accomodated by the programmer.
3. When programming the AT27LV020A a 0.1 µF capacitor is required across VPP and ground to suppress spurious voltage
transients.
