AT27BV040
Description
The AT27BV040 chip is a high performance, low power, low voltage, 4,194,304 bit
one-time programmable read only memory (EPROM) organized as 512K by 8 bits. It
requires only one supply in the range of 2.7 to 3.6V in normal read mode operation,
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 100 ns. With a typical power dissipation of only 18 mW at 5
MHz and V
CC
= 3V, the AT27BV040 consumes less than one fifth the power of a
standard 5V EPROM. Standby mode supply current is typically less than 1
μ
A at 3V.
The AT27BV040 simplifies system design and stretches battery lifetime even further
by eliminating the need for power supply regulation.
