The Microchip AT27BV256-70JU-T is a high-performance, low-power, Battery-Voltage256-kbit One Time Programmable EPROM organized as 32-Kbit x 8. Requiring asingle power supply in the range of 2.7V to 3.6V; any byte can be accessed inless than 70 ns. With typical power consumption of only 18 mW at 5 MHz and VCC= 3V, the AT27BV256-70JU-T consumes less than one-fifth the power of a standard, 5VEPROM, making it ideal for fast, portable systems using either regulated orunregulated battery power.
