Description

The AT27BV512 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.  AT27BV512-90RC requires only one supply in the range of 2.7V to 3.6V in normal read mode operation, making it ideal for fast, portable systems using either regulated or unregulated battery power.

Atmel's innovative design techniques of AT27BV512-90RC provide fast speeds that rival 5V parts while keeping the low power consumption of a 3V supply. At V_CC = 2.7V, any byte can be accessed in less than 90 ns. With a typical power consumption of only 18 mW at 5 MHz and V_CC = 3V, the AT27BV512 consumes less than one fifth the power of a standard 5V EPROM.

Standby mode supply current of AT27BV512-90RC is typically less than 1 µA at 3V. The AT27BV512 simplifies system design and stretches battery lifetime even further by eliminating the need for power supply regulation.

The AT27BV512 is available in industry standard JEDEC-approved one-time programmable (OTP) plastic PLCC, SOIC, and TSOP packages. All devices feature two-line control (CE, OE) to give designers the flexibility to prevent bus contention.

The AT27BV512 operating with VCC 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 compatible with JEDEC approved low voltage battery operation (LVBO) interface specifications. The device is also capable of standard 5-volt operation making it ideally suited for dual supply range systems or card products that are pluggable in both 3-volt and 5-volt hosts.

Atmel's AT27BV512 has additional features to ensure high quality and efficient production use. The Rapid^TM Programming Algorithm reduces the time required to program the part and guarantees reliable programming. Programming time is typically only 100 µs/byte. The Integrated Product Identification Code electronically identifies the device and manufacturer. AT27BV512-90RC feature is used by industry standard programming equipment to select the proper programming algorithms and voltages. The AT27BV512 programs exactly the same way as a standard 5V AT27C512R and uses the same programming equipment.
