AT27C040-90PU 4Mbit, OTP EPROM存储器PDIP-32封装

4M bit EPROM

The AT27C040 chip is a low-power, high-performance, 4,194,304-bit one-time programmable read-only memory (OTP EPROM) organized as 512K by 8 bits. The AT27C040 requires only one 5V power supply in normal read mode operation. Any byte can be accessed in less than 70 ns, eliminating the need for speed reducing WAIT states on high-performance microprocessor systems. Atmel’s scaled CMOS technology provides low active power consumption, and fast programming. Power consumption is typically 8 mA in active mode and less than 10 μA in standby mode.

The AT27C040 is available in a choice of industry-standard JEDEC-approved onetime programmable (OTP) plastic PDIP, PLCC and TSOP packages. The device features two-line control (CE, OE) to eliminate bus contention in high-speed systems. Atmel’s 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 100 μs/byte. The Integrated Product Identification Code electronically identifies the device and manufacturer. This feature is used by industry-standard programming equipment to select the proper programming algorithms and voltages.
