Description
The AT27C512R is a low-power, high performance 524,288 bit one-time program-
mable 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 per-
formance microprocessor systems.
Atmel鈥檚 scaled CMOS technology provides high speed, lower active power con-
sumption, and significantly faster programming. Power consumption is typically only
8 mA in Active Mode and less than 10

in Standby.
