Description

The AT27BV010 is a high-performance, low-power, low-voltage 1,048,576-bit one-

time programmable read-only memory (OTP EPROM) organized as 128K 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

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

V

EPROM. Standby mode supply current is typically less than 1 µA at 3V. The

AT27BV010 simplifies system design and stretches battery lifetime even further by

eliminating the need for power supply regulation.

The AT27BV010 is available in industry-standard JEDEC-approved one-time

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

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

The AT27BV010 operating with V

patible with standard TTL logic devices operating at V

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.
