the CY7C261 automatically powers down into a low-power
standby mode. It is packaged in a 300-mil-wide package. The
CY7C263 and CY7C264 are packaged in 300-mil-wide and
600-mil-wide packages respectively, and do not power down
when deselected. The reprogrammable packages are
equipped with an erasure window; when exposed to UV light,
these PROMs are erased and can then be reprogrammed.
The memory cells utilize proven EPROM floating-gate
technology and byte-wide intelligent 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
programming the product will meet DC and AC specification
limits.
Read is accomplished by placing an active LOW signal on CS.
