Product Overview

The AT27C040-70JU is a low-power high-performance 4194304-bit One-Time Programmable Read-Only Memory (OTP EPROM) organized as 512K by 8-bit. The AT27C040 requires only one 5V power supply in normal read mode operation. Any byte can be accessed in less than 70ns, eliminating the need for speed reducing wait states on high-performance microprocessor systems. The Atmel scaled CMOS technology provides low active power consumption and fast programming. Power consumption is typically 8mA in active mode and less than 10μA in standby mode. The device features two-line control (CE, OE) to eliminate bus contention in high-speed systems. The AT27C040 has additional features to ensure high quality and efficient production use. The rapid programming algorithm reduces the time required to program the part and guarantees reliable programming. Programming time is typically only 100μs/byte. The integrated product identification code electronically identifies the device and manufacturer.
