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
μ
A in Standby.
