Description
new designs
The Atmel 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.
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 byte can be accessed in
less than 90ns. With a typical power dissipation of only 18mW at 5MHz 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 1μA 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 programma-
ble (OTP) PLCC and plastic TSOP packages. All devices feature two-line control (CE, OE)
to give designers the flexibility to prevent bus contention.
The AT27BV020 operating with V CC at 3.0V produces TTL-level outputs that are compatible
with standard TTL logic devices operating at V CC = 5.0V. At V CC = 2.7V, the part is compati-
ble with JEDEC-approved, low-voltage battery operation (LVBO) interface specifications.
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 Atmel AT27BV020 has additional features to ensure high quality and efficient produc-
tion use. The rapid programming algorithm reduces the time required to program the part
