AT27C512R-90PC [Microchip]

The AT27C512R is a low-power, high-performance 524,288-bit one-time programmable read only memory (OTP EPROM) organized 64K by 8 bits. It requires only one 5V power supply in normal read mode operation. Any byte can be accessed in less than 45 ns, eliminating the need for speed reducing WAIT states on high-performance microprocessor systems. Atmel’s scaled CMOS technology provides high-speed, lower active power consumption, and significantly faster programming. Power consumption is typically only 8 mA in Active Mode and less than 10 mA in Standby. Features include JEDEC standard packages, 5V ±10% supply, high-reliability CMOS technology with 2000V ESD protection and 200 mA latchup immunity, Rapid™ programming algorithm (100 μs/byte), CMOS and TTL compatible inputs and outputs, integrated product identification code, and commercial, industrial and automotive temperature ranges.
