The x16 organization makes this part ideal for portable and hand held 16- and 32-bit microprocessor based 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 word can be accessed in less than 120ns. With a typical power dissipation of only 10 mW at 5mHZ and VCC = 3V, the AT27BV800 consumes less than one fifth the power of a standard 5V EPROM. Standby mode supply current is typically less than 1 mA at 3V. The AT27BV800 simplifies system design and stretches battery lifetime even further by eliminating the need for power supply regulation. The AT27BV800 can be organized .
