AT27C512R  
Description  
The AT27C512R is a low-power, high-performance 524,288-bit one-time programma-  
ble 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 consump-  
tion, and significantly faster programming. Power consumption is typically only 8 mA  
in Active Mode and less than 10 µA in Standby.
