AT27BV010-70JI

The AT27BV010 is a high performance, low power, low voltage 1,048,576 bit onetime programmable read only memory (OTP EPROM) organized as 128K by 8 bits. AT27BV010-70JI 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 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 70 ns. With a typical power draw of only 18 mW at 5 MHz and VCC = 3V, the AT27BV010 consumes less than one fifth the power of a standard 5V EPROM. Standby mode supply current is typically less than 1 µA at 3V. The AT27BV010 simplifies system design and stretches battery lifetime even further by eliminating the need for power supply regulation.

The AT27BV010 is available in industry standard JEDEC approved one-time programmable (OTP) plastic PLCC and TSOP  packages. All devices feature two-line control (CE, OE) to give designers the flexibility to prevent bus contention.

The AT27BV010 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 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 AT27BV010 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. This feature is used by industry standard programming equipment to select the proper programming algorithms and voltages. The AT27BV010 programs exactly the same way as a standard 5V AT27C010 and uses the same programming equipment.
