FINAL
Am27C4096
4 Megabit (256 K x 16-Bit) CMOS EPROM
DISTINCTIVE CHARACTERISTICS
■ Fast access time
— Speed options as fast as 90 ns
■ Low power consumption
— 100 µA maximum CMOS standby current
■ JEDEC-approved pinout
— Plug-in upgrade of 1 Mbit and 2 Mbit EPROMs
— 40-pin DIP/PDIP
— 44-pin PLCC
GENERAL DESCRIPTION
The Am27C4096 is a 4 Mbit, ultraviolet erasable programmable read-only memor y. 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 available in windowed ceramic DIP packages, and plastic
one time programmable (OTP) PDIP and PLCC packages.
Data can be typically accessed in less than 90 ns, allowing high-p erformance m icroproces sors to ope rate
without any WAIT states. The device offers separate
Output Enable (OE#) and Chip Enable (CE#) controls,
■ Single +5 V power supply
■ ±10% power supply tolerance standard
■ 100% Flashrite programming
— Typical programming time of 32 seconds
■ Latch-up protected to 100 mA from –1 V to
+ 1 V
V
CC
■ High noise immunity
thus eliminating bus contention in a mul tiple bus microprocessor 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 signals. Bit locations may be programmed singly, in
blocks, or at random. The devi ce supports AMD’s
Flashrite programming alg orithm (100 µs pulses), resulting in a typical programming time of 32 seconds.
