AT27C256R

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.
