Description
The Atmel AT27LV512A is a high-performance, low-power, low-voltage, 524,288-bit, one
time programmable, read-only memory (OTP EPROM) organized as 64K by 8 bits. It
requires only one supply in the range of 3.0 to 3.6V in normal read mode operation, making
it ideal for fast, portable systems using battery power.
The Atmel innovative design techniques provide fast speeds that rival 5V parts, while keep
ing the low power consumption of a 3.3V supply. At VCC = 3.0V, any byte can be accessed
in less than 90ns. With a typical power dissipation of only 18mW at 5MHz and VCC = 3.3V,
the AT27LV512A consumes less than one-fifth the power of a standard, 5V EPROM.
Standby mode supply current is typically less than 1µA at 3.3V.
The AT27LV512A is available in industry-standard, JEDEC-approved, one-time
programmable (OTP) PLCC package. All devices feature two-line control (CE, OE) to give
designers the flexibility to prevent bus contention.
The AT27LV512A operating with VCC at 3.0V produces TTL-level outputs that are compati
ble with standard TTL logic devices operating at VCC = 5.0V. The device is also capable of
standard, 5V operation, making it ideally suited for dual supply range systems or card prod
ucts that are pluggable in both 3V and 5V hosts.
The AT27LV512A has additional features to ensure high quality and efficient production use.
The rapid programming algorithm reduces the time required to program the part and guar
antees reliable programming. Programming time is typically only 100µs/byte. The
integrated product identification code electronically identifies the device and manufacturer.
This feature is used by industry standard programming equipment to select the proper pro
gramming algorithms and voltages. The AT27LV512A programs in exactly the same way as
a standard, 5V Atmel AT27C512R, and uses the same programming equipment
