1. Description

The AT27LV512A 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 3.0 to 3.6V in normal read mode operation,

making it ideal for fast, portable systems using battery power.

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

accessed in less than 90 ns. With a typical power dissipation of only 18 mW at 5 MHz

and V

dard 5V EPROM. Standby mode supply current is typically less than 1 µA at 3.3V.

The AT27LV512A is available in industry-standard JEDEC-approved one-time

programmable (OTP) plastic PLCC, SOIC, and TSOP packages. All devices feature

two-line control (CE, OE) to give designers the flexibility to prevent bus contention.

The AT27LV512A operating with V

compatible with standard TTL logic devices operating at V

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.

Atmel’s AT27LV512A has additional features to ensure high quality and efficient pro-

duction use. The Rapid Programming Algorithm reduces the time required to program

the part and guarantees reliable programming. Programming time is typically only

100 µs/byte. The Integrated Product Identification Code electronically identifies the

device and manufacturer. This feature is used by industry-standard programming

equipment to select the proper programming algorithms and voltages. The

AT27LV512A programs exactly the same way as a standard 5V AT27C512R and

uses the same programming equipment.
