8M bit EPROM
The AT27C080 chip 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 requires only one 5V power supply in normal read mode operation. Any byte can be accessed in less than 90 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 10 mA in active mode and less than 10 μA in standby mode.
The AT27C080 is available in a choice of packages, including; one-time programmable (OTP) plastic PLCC, PDIP and TSOP. All devices feature two-line control (CE,OE) to give designers the flexibility to prevent bus contention. With high density 1-Mbyte storage capability, the AT27C080 allows firmware to be stored reliably and to be accessed by the system without the delays of mass storage media. Atmel’s AT27C080 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 50 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.
