Atmel AT27C080

Description
The Atmel ? AT27C080 is a low-power, high-performance 8,388,608-bit, one-time pro-
grammable, 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 90ns, 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 pro-
gramming. Power consumption is typically 10mA in active mode and less than 10μA in
standby mode.
The AT27C080 is available in a choice of industry standard, JEDEC-approved, one-time pro-
grammable (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 allows firmware to be stored reli-
ably and to be accessed by the system without the delays of mass storage media.
The 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 guar-
antees 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.
