Functional Description
The CY7C261, CY7C263, and CY7C264 are high-perfor-
mance 8192-word by 8-bit CMOS PROMs. When deselected,
the 7C261 automatically powers down into a low-power stand-
by mode. It is packaged in a 300-mil-wide package. The 7C263
and 7C264 are packaged in 300-mil-wide and 600-mil-wide
packages respectively, and do not power down when deselect-
ed. The reprogrammable packages are equipped with an era-
sure window; when exposed to UV light, these PROMs are
erased and can then be reprogrammed. The memory cells uti-
lize proven EPROM floating-gate technology and byte-wide in-
telligent programming algorithms.
The CY7C261, CY7C263, and CY7C264 are plug-in replace-
ments for bipolar devices and offer the advantages of lower
power, superior performance and programming yield. The
EPROM cell requires only 12.5V for the supervoltage 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 program-
ming the product will meet DC and AC specification limits.
Read is accomplished by placing an active LOW signal on CS.
The contents of the memory location addressed by the ad-
dress line (A
0
−A
12
) will become available on the output lines
(O
0
−O
7
).
