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.
