Product Summary
The AT27C512R-70PU is a low-power, high-performance 524,288-bit one-time programma-ble read-only memory (OTP EPROM) organized 64K by 8 bits. The AT27C512R-70PU requires only one 5V power supply in normal read mode operation. Any byte can be accessed in less than45 ns, eliminating the need for speed reducing WAIT states on high-performancemicroprocessor 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 μA in Standby.
