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 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 typical programming time of 1 minute.
