GENERAL DESCRIPTION
The Am27C512 is a 512-Kbit, ultraviolet erasable programmable read-only memory. It is organized as 64K
words by 8 bits per word, operates from a single +5 V
supply, has a static standby mode, and features fast
single address location programming. Products are
available in windowed ceramic DIP packages, as well
as plastic one time programmable (OTP) PDIP and
PLCC packages.
Data can be typically accessed in less than 55 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,
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 80 mW in active mode, and
100 µW in standby mode.
All signals are TTL levels, including programming signals. Bit locations may be programmed singly, in
blocks, or at random. The device supports AMD’s
Flashrite programming alg orithm (100 µs pulses), resulting in a typical programming time of 8 seconds.
