AT27C080-90JU

The AT27C080 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 90ns, eliminating the need for speed reducing WAIT states on high-performance microprocessor systems. The 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 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 allows firmware to be stored reliably and to be accessed by the system without the delays of mass storage media.
