1. Description

The AT27BV256 is a high-performance, low-power, low-voltage 262,144-bit one-time

programmable read-only memory (OTP EPROM) organized as 32K by 8 bits. It

requires only one supply in the range of 2.7V to 3.6V in normal read mode operation,

making it ideal for fast, portable systems using either regulated or unregulated battery

power.

Atmel’s innovative design techniques provide fast speeds that rival 5V parts while

keeping the low power consumption of a 3V supply. At V_CC= 2.7V, any word can be

accessed in less than 70 ns. With a typical power dissipation of only 18 mW at 5 MHz

and V_CC= 3V, the AT27BV256 consumes less than one fifth the power of a standard

5V EPROM.

Standby mode supply current is typically less than 1 µA at 3V. The AT27BV256 simpli-

fies system design and stretches battery lifetime even further by eliminating the need

for power supply regulation.

The AT27BV256 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 AT27BV256 operating with V_CCat 3.0V produces TTL level outputs that are com-

patible with standard TTL logic devices operating at V_CC= 5.0V. At V_CC= 2.7V, the

part is compatible with JEDEC approved low voltage battery operation (LVBO) inter-

face specifications. 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.
