Functional Description
The CY7C276 is a high-performance 16K-word by 16-bit
CMOS PROM. It is available in a 44-pin PLCC/CLCC and a
44-pin LCC packages, and is 100% reprogrammable in win-
dowed packages. The memory cells utilize proven EPROM
floating gate technology and word-wide programming algo-
rithms.
The CY7C276 allows the user to independently program the
polarity of each chip select (CS
decoding of up to eight banks of PROM. The polarity of the
asynchronous output enable pin (OE) is also programmable.
In order to read the CY7C276, all three chip selects must be
active and OE must be asserted. The contents of the memory
location addressed by the address lines (A
available on the output lines (D
the outputs until the address changes or the outputs are dis-
abled.
