DESCRIPTION
The Atmel AT27LV512A is a high-performance, low-power, low-voltage, 524,288-bit, onetime 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 keeping 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 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 systems or card products 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 guarantees 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 programming algorithms and voltages. The AT27LV512A programs in exactly the same way as a standard, 5V Atmel AT27C512R, and uses the same programming equipment.
