The Microchip AT27C040 is a low-power, high-performance, 4-megabitOne Time Programmable EPROM organized as 512-Kbit x 8. Requiring a single 5Vpower supply, in normal read mode operation typical power consumption is only 8mA in active mode and less than 10 μA in standby mode. Any byte can be accessedin less than 70 ns, eliminating the need for speed reducing WAIT states onhigh-performance microprocessor systems.
Description
The Atmel® AT27C040 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 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 AT27C040 is available in a choice of industry standard, JEDEC-approved, PDIP and PLCC packages. 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. This feature is used by industry standard programming equipment to select the proper programming algorithms and voltages.
