GENERAL DESCRIPTION
The Am27C64 is a 64-Kbit ultraviolet erasable program- controls, thus eliminating bus contention in a multiple
mable read-only memory. It is organized as 8K words by bus microprocessor system.
8 bits per word, operates from a single +5 V supply, has AMD’s CMOS process technology provides high speed,
a static standby mode, and features fast single address low power, and high noise immunity. Typical power con-
location programming. Products are available in win-
sumption is only 80 mW in active mode, and 100 µW in
dtimoweepdrocgerraammmicabDlIeP(OpaTcPk)aPgDesIPa, sanwdePllLaCsCpplaasctDkicaagotaensSe.heet4sUta.cnodmby mode.
All signals are TTL levels, including programming sig-
Typically, any byte can be accessed in less than 45 ns, nals. Bit locations may be programmed singly, in blocks,
allowing operation with high-performance microproces- or at random. The Am27C64 supports AMD’s Flashrite
sors without any WAIT states. The Am27C64 offers
separate Output Enable (OE) and Chip Enable (CE)
programming algorithm (100 µs pulses) resulting in a
typical programming time of 1 second.
