Description
The AT27LV512A is a high performance, low power, low voltage 524,288 bit one-time
programmable read only memory (OTP EPROM) organized as 64K by 8 bits. It re-
quires only one supply in the range of 3.0V to 3.6V in normal read mode operation,
making it ideal for fast, portable systems using battery power.
Atmel鈥檚 innovative design techniques provide fast speeds that rival 5V parts while
keeping the low power consumption of a 3.3V supply. At V
CC
= 3.0V, any byte can be
accessed in less than 90 ns. With a typical power dissipation of only 18 mW at 5 MHz
and V
CC
= 3.3V, the AT27LV512A consumes less than one fifth the power of a stand-
ard 5V EPROM.
