Am27C4096
4 Megabit (256 K x 16-Bit) CMOS EPROM
DISTINCTIVE CHARACTERISTICS
GENERAL DESCRIPTION
The Am27C4096 is a 4 Mbit, ultraviolet erasable pro-
grammable read-only memory. It is organized as 256
Kwords, operates from a single +5 V supply, has a
static standby mode, and features fast single address
location programming. The Am27C4096 is ideal for use
in 16-bit microprocessor systems. The device is avail-
able in windowed ceramic DIP packages, and plastic
one time programmable (OTP) PDIP and PLCC pack-
ages.
Data can be typically accessed in less than 90 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 125 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 32 seconds.
