Description

The AT27LV520 is a low-power, high-performance, 524,288-bit one-time programmable read-only memory (OTP EPROM) organized 64K by eight bits. It incorporates latches for the eight lower order address bits to multiplex with the eight data bits. This minimizes system chip count, reduces cost, and simplifies the design of multiplexed bus systems. It requires only one power supply in the range of 3.0V to 3.6V for normal read mode operation, making it ideal for fast, portable systems using battery power. Any byte can be accessed in less than 70 ns.
