Description
Atmel AT27BV1024
The Atmel AT27BV1024 is a high-performance, low-power, low-voltage, 1,048,576-bit,
one-time programmable, read-only memory (OTP EPROM) organized as 64K by 16 bits. It
requires only one supply in the range of 2.7V to 3.6V in normal read mode operation. The
x16 organization makes this part ideal for portable and handheld 16- and 32-bit micropro-
cessor-based systems using either regulated or unregulated battery power.
The Atmel innovative design techniques provide fast speeds that rival 5V parts, while keep-
ing the low power consumption of a 3V supply. At V CC = 2.7V, any word can be accessed in
less than 90ns. With a typical power dissipation of only 18mW at 5MHz and V CC = 3V, the
AT27BV1024 consumes less than one-fifth the power of a standard, 5V EPROM.
Standby mode supply current is typically less than 1μA at 3V. The AT27BV1024 simplifies
system design and stretches battery lifetime even further by eliminating the need for power
supply regulation.
The AT27BV1024 is available in an industry-standard, JEDEC-approved, one-time pro-
grammable (OTP) PLCC package. All devices feature two-line control (CE, OE) to give
designers the flexibility to prevent bus contention.
The AT27BV1024 operating with V CC at 3.0V produces TTL-level outputs that are compati-
ble 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) interface specifi-
cations. The device is also capable of standard, 5V operation making it ideally suited for dual
supply range systems or card products that are pluggable in both 3V and 5V hosts.
The AT27BV1024 has additional features to ensure high quality and efficient
production use. The rapid programming algorithm reduces the time required to program the
part and guarantees reliable programming. Programming time is typically only 100 μs/word.
The integrated product identification code electronically identifies the device and
