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.

Notes:
1. Minimum DC voltage on input or I/O pins –0.5 V. During
voltage transitions, the input may overshoot VSS to –2.0 V
for periods of up to 20 ns. Maximum DC voltage on input
and I/O pins is VCC + 5 V. During voltage transitions, input
and I/O pins may overshoot to VCC + 2.0 V for periods up
to 20 ns.
2. Minimum DC input voltage on A9 is –0.5 V. During voltage
transitions, A9 and VPP may overshoot VSS to –2.0 V for
periods of up to 20 ns. A9 and VPP must not exceed+13.5
V at any time.
Stresses above those listed under “Absolute Maximum Rat-
ings” may cause permanent damage to the device. This is a
stress rating only; functional operation of the device at these
or any other conditions above those indicated in the opera-
tional sections of this specification is not implied. Exposure of
the device to absolute maximum ratings for extended periods
may affect device reliability.
