GENERAL DESCRIPTION

The Am27C2048 is a 2 Mbit, ultraviolet erasable pro-

grammable read-only memory. It is organized as 128 K

words, operates from a single +5 V supply, has a static

standby mode, and features fast single address loca-

tion programming. The Am27C2048 is ideal for use in

16-bit microprocessor systems. The device is available

in windowed ceramic DIP packages, and plastic one

time programmable (OTP) PDIP and PLCC packages.

Data can be typically accessed in less than 55 ns, al-

lowing high-performance microprocessors to operate

without any WAIT states. The device offers separate

Output Enable (OE#) and Chip Enable (CE#) controls,

thus eliminating bus contention in a multiple bus micro-

processor system.

AMD’s CMOS process technology provides high

speed, low power, and high noise immunity. Typical

power consumption is only 125 mW in active mode,

and 100 µW in standby mode.

All signals are TTL levels, including programming sig-

nals. Bit locations may be programmed singly, in

blocks, or at random. The device supports AMD’s

Flashrite programming algorithm (100 µs pulses), re-

sulting in a typical programming time of 16 seconds.
