AT27LV040A

The Microchip AT27LV040A is a high-performance, low-power, low-voltage, 4-megabit One Time Programmable EPROM organized as 512-Kbit x 8. Requiring a single power supply in the range of 3.0V to 3.6V in normal read mode operation any byte can be accessed in less than 90 ns. With typical power consumption of only 18 mW at 5 MHz and VCC = 3.3V, the AT27LV040A consumes less than one-half the power of a standard, 5V EPROM. Standby mode supply current is typically less than 1 μA at 3.3V making it ideal for fast, portable systems using battery power.
