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 2.7 to 3.6V in normal read mode operation, making it ideal for fast, portable systems using either regulated or unregulated battery power.
