Device Overview

Summary

The Microchip AT27BV256 is a high-performance, low-power, Battery-Voltage 256-kbit One Time Programmable EPROM organized as 32-Kbit x 8. Requiring a single power supply in the range of 2.7V to 3.6V; any byte can be accessed in less than 70 ns. With typical power consumption of only 18 mW at 5 MHz and VCC = 3V, the AT27BV256 consumes less than one-fifth the power of a standard, 5V EPROM, making it ideal for fast, portable systems using either regulated or unregulated battery power.
