Products Detail

The AT27C040 is a 4Mbit OTP EPROM organized as 512K x 8. It requires a single 5V power supply and features fast read access time of 70 ns. The device uses Atmel's scaled CMOS technology for low active power consumption (typically 8 mA at 5 MHz) and fast programming (100 µs/byte). It is available in industry-standard packages including PDIP, SOIC, PLCC, and TSOP. The chip features two-line control (CE, OE) to eliminate bus contention in high-speed systems. It has high reliability with 2000V ESD protection and 200 mA latchup immunity. The Rapid Programming Algorithm reduces programming time and ensures reliability. The Integrated Product Identification Code allows for electronic identification by industry-standard programming equipment.
