AT27BV020
1. Description
The AT27BV020 is a high-performance, low-power, low-voltage, 2,097,152-bit, one-
time programmable, read-only memory (OTP EPROM) organized as 256K by 8 bits. It
requires only one supply in the range of 2.7 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 byte can be
accessed in less than 90 ns. With a typical power dissipation of only 18 mW at 5 MHz
and V
CC
= 3V, the AT27BV020 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
AT27BV020 simplifies system design and stretches battery lifetime even further by
eliminating the need for power supply regulation
The AT27BV020 is available in industry-standard JEDEC approved one-time pro-
grammable (OTP) plastic PLCC, TSOP and VSOP packages, as well as a 42-ball,
1 mm pitch. All devices feature two-line control (CE, OE) to give designers the flexibil-
ity to prevent bus contention.
The AT27BV020 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. 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.
