GENERAL DESCRIPTION
The Am27C040 is a 4 Mbit ultraviolet erasable pro-
grammable read-only memory. It is organized as 512K
bytes, operates from a single +5 V supply, has a static
standby mode, and features fast single address loca-
tion programming. The device is available in windowed
ceramic DIP packages and plastic one-time program-
mable (OTP) packages.
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 100 mW in active mode,
and 50 W 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 s pulses) re-
sulting in typical programming time of 1 minute.
