AT27BV1024
Description
The AT27BV1024 is a high performance, low power, low voltage 1,048,576 bit one-
time programmable read only memory (OTP EPROM) organized as 64K by 16 bits.
It requires only one supply in the range of 2.7V to 3.6V in normal read mode opera-
tion. The by-16 organization makes this part ideal for portable and handheld 16 and
32 bit microprocessor based systems using either regulated or unregulated battery
power.
