Description
The AT27LV520 is a low-power, high-performance, 524,288-bit one-time programma-
ble 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.
The AT27LV520 is available in 173 mil, 20-lead TSSOP and 300 mil, 20-lead SOIC,
one-time programmable (OTP) plastic packages.
