GENERAL DESCRIPTION  
The Am27C256 is a 256K-bit ultraviolet erasable pro-  
grammable read-only memory. It is organized as 32K  
words by 8 bits per word, operates from a single +5 V  
supply, has a static standby mode, and features fast sin-  
gle address location programming. Products are avail-  
ableinwindowedceramicDIPpackagesaswellasplas-  
tic one time programmable (OTP) PDIP, TSOP, and  
PLCC packages.  
controls, thus eliminating bus contention in a multiple  
bus microprocessor system.  
AMD’s CMOS process technology provides high speed,  
low power, and high noise immunity. Typical power con-  
sumption is only 80 mW in active mode, and 100 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 Am27C256 supports AMD’s Flashrite  
programming algorithm (100 µs pulses) resulting in typi-  
cal programming time of 4 seconds.  
Typically, any byte can be accessed in less than 55 ns,  
allowing operation with high-performance microproces-  
sors without any WAIT states. The Am27C256 offers  
separate Output Enable (OE) and Chip Enable (CE)
