27C010-45 1024K 45ns CMOS EPROM

Contents hide

The AT27C010(L) is a low-power, high-performance 1,048,576-bit one-time programmable 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-performance microprocessor systems. Two power versions are offered. In read mode, the AT27C010 typically consumes 25 mA while the AT27C010L requires only 8 mA. The standby mode supply current for both parts is typically less than 10 µA.
