1-Megabit
(128K x 8)
OTP EPROM
AT27C010(L)
Description
The AT27C010(L) is a low-power, high-performance 1,048,576-bit one-time program-
mable read only memory (OTP EPROM) organized as 128K by 8 bits. They require
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.
Two power versions are offered. In read mode, the AT27C010 typically consumes 25
mA while the AT27C010L requires only 8 mA. Standby mode supply current for both
parts is typically less than 10 碌A(chǔ).
