The Microchip AT27C020 is a low-power, high-performance, 2-megabit One Time Programmable EPROM organized as 256-Kbit x 8. Requiring a single 5V power supply, in normal read mode operation typical power consumption is only 8 mA and standby mode supply current is typically less than 10 μA. Any byte can be accessed in less than 55 ns, thus eliminating the need for speed-reducing WAIT states on high performance microprocessor systems.
