Description
The AT27LV520 is a low-power, high-performance 524,288-bit one-time programma-
ble read only memory (OTP EPROM) organized 64K by 8 bits. It incorporates latches
for the 8 lower order address bits to multiplex with the 8 data bits. This minimizes sys-
tem 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 90 ns.
The AT27LV520 is available in 173 mil, 20-pin TSSOP, 300 mil, 20-pin SOIC and 28-
pin TSOP, one-time programmable (OTP) plastic packages.
