AT27LV520
1. 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
Not Recommended
for New Designs.
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 20-lead TSSOP and 20-lead SOIC, one-time program-
mable (OTP) plastic packages.
Atmel’s innovative design techniques provide fast speeds that rival 5V parts while
keeping the low power consumption of a 3.3V supply. At V CC = 3.0V, any byte can be
accessed in less than 70 ns. With a typical power dissipation of only 18 mW at 5 MHz
and V CC = 3.3V, the AT27LV520 consumes less than one fifth the power of a standard
5V EPROM. Standby mode is achieved by asserting ALE high. Standby mode supply
current is typically less than 1 μA at 3.3V.
The AT27LV520 operating with V CC at 3.0V produces TTL level outputs that are com-
patible with standard TTL logic devices operating at V CC = 5.0V. The device is also
capable of standard 5-volt operation making it ideally suited for dual supply range
systems or card products that are pluggable in both 3-volt and 5-volt hosts.
