Description The Atmel AT27LV040A is a high-performance, low-power, low-voltage, 4,194,304-bit, one-time programmable, read-only memory (OTP EPROM) organized as 512K 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 keeping the low power consumption of a 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 AT27LV040A consumes less than one-half the power of a standard, 5V EPROM.
Standby mode supply current is typically less than 1µA at 3.
3V.
The AT27LV040A is available inan 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 AT27LV040A operating with VCC at 3.
0V produces TTL-level outputs that are compatible 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 syste...
