Am27C128
128 Kilobit (16 K x 8-Bit) CMOS EPROM
DISTINCTIVE CHARACTERISTICS
GENERAL DESCRIPTION
The Am27C128 is a 128-Kbit, ultraviolet erasable pro-
grammable read-only memory. It is organized as 16
Kwords by 8 bits per word, operates from a single +5 V
supply, has a static standby mode, and features fast
single address location programming. Products are
available in windowed ceramic DIP packages, as well
as plastic one time programmable (OTP) PDIP and
PLCC packages.
Data can be typically accessed in less than 45 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 80 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 2 seconds.
Latch-up protected to 100 mA from –1 V to
V
High noise immunity
Versatile features for simple interfacing
— Both CMOS and TTL input/output compatibility
— Two line control functions
