Description
The AT27BV010 is a high performance, low power, low voltage 1,048,576 bit one-
time programmable read only memory (OTP EPROM) organized as 128K by 8 bits.
It requires only one supply in the range of 2.7V to 3.6V in normal read mode opera-
tion, making it ideal for fast, portable systems using either regulated or unregulated
battery power.
Atmel’s innovative design techniques provide fast speeds that rival 5V parts while
keeping the low power consumption of a 3V supply. At V
CC
= 2.7V, any byte can be
accessed in less than 70 ns. With a typical power draw of only 18 mW at 5 MHz and
V
CC
= 3V, the AT27BV010 consumes less than one fifth the power of a standard 5V
