Description  
The AT27C256R is a low-power, high performance 262,144 bit one-time programma-  
ble read only memory (OTP EPROM) organized 32K 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 low active power consumption, and fast  
programming. Power consumption is typically only 8 mA in Active Mode and less  
than 10 µA in Standby.
