Functional Description
The CY7C266 is a high-performance 8192-word by 8-bit
CMOS PROM. When deselected, the CY7C266 automatically
powers down into a low-power standby mode. It is packaged
in a 600-mil-wide package. The reprogrammable packages
are equipped with an erasure window; when exposed to UV
light, these PROMs are erased and can then be repro-
grammed. The memory cells utilize proven EPROM
floating-gate
technology
programming algorithms.
The CY7C266 is a plug-in replacement for EPROM devices.
The EPROM cell requires only 12.5V for the super voltage and
low-current requirements allow for gang programming. The
EPROM cells allow for each memory location to be tested
100%, as each location is written into, erased, and repeatedly
exercised prior to encapsulation. Each PROM is also tested
for AC performance to guarantee that after customer
programming, the product will meet DC and AC specification
limits.
Reading is accomplished by placing an active LOW signal on
OE and CE. The contents of the memory location addressed
by the address lines (A
0
through A
12
) will become available on
the output lines (O
0
through O
7
).
