Description
The AT27BV512 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 requires only one supply in the range of 2.7V to 3.6V in normal read mode operation, making it ideal for fast, portable systems using either regulated or unregulated battery power.
