MICROCHIP AT27C040-12JI

The AT27C040 is a low-power, high-performance 4,194,304-bit OTP EPROM organized as 512K×8 bits. The AT27C040 requires only a single 5V supply in normal read mode operation. Any byte can be accessed in less than 70 ns, eliminating the need for speed-reducing wait states in high-performance microprocessor systems. Atmel's scaled CMOS technology provides low dynamic power consumption and fast programming capability. Power consumption is typically 8 mA in active mode and less than 10 μA in standby mode. The AT27C040 is available in industry-standard JEDEC-approved 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 incorporates additional features to ensure high quality and efficient production use. A fast programming algorithm reduces the time required to program the device while guaranteeing reliable programming. Programming time is typically only 100 μs/byte. An integrated Product Identification Code enables electronic identification of the device and manufacturer. This feature is used by industry-standard programming equipment to select the appropriate programming algorithm and voltage.
