MICROCHIP AT27BV010-90JU

The Atmel 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. It 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. The innovative Atmel design techniques provide fast speeds that rival 5V parts, while keeping the low power consumption of a 3V supply. At VCC = 2.7V, any byte can be accessed in less than 90ns. With a typical power draw of only 18mW at 5MHz and VCC = 3VZ, the AT27BV010 consumes less than one-fifth the power of a standard, 5V EPROM. Standby mode supply current is typically less than 1μA 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 an 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 AT27BV010 operating with VCC at 3.0V produces TTL-level outputs that are compatible with standard TTL logic devices operating at VCC = 5.0V. At VCC = 2.7V, the part is compatible with JEDEC-approved, low-voltage battery operation (LVBO) interface specifications. 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 AT27BV010 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.
