AT27C080-90TU Datasheet



The Atmel® AT27C080-90TU is a low-power, high-performance 8,388,608-bit, one-time programmable, read-only memory (OTP EPROM) organized as 1M by 8 bits. The AT27C080-90TU requires only one 5V power supply in normal read mode operation. Any byte can be accessed in less than 90ns, eliminating the need for speed reducing WAIT states on highperformance microprocessor systems.Atmel scaled CMOS technology provides low active power consumption and fast programming. Power consumption is typically 10mA in active mode and less than 10µA in standby mode.The AT27C080-90TU is available in a choice of industry standard, JEDEC-approved, one-time programmable (OTP) PLCC and PDIP packages. All devices feature two-line control (CE, OE) to give designers the flexibility to prevent bus contention.With high-density, 8Mb storage capability, the AT27C080-90TU allows firmware to be stored reliably and to be accessed by the system without the delays of mass storage media.The AT27C080-90TU has additional features to ensure high quality and efficient production use. The rapidprogramming algorithm reduces the time required to program the part and guarantees reliable programming. Programming time is typically only 50µs/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.
