Functional Description
The CY27C256 is a high-performance 32,768-word by 8-bit
CMOS EPROM. When disabled (CE HIGH), the CY27C256
automatically powers down into a low-power stand-by mode.
The CY27C256 is packaged in the industry standard 600-mil
DIP, PLCC, and TSOP packages. The CY27C256 is also available
in a CerDIP package equipped with an erasure window
to provide for reprogrammability. When exposed to UV light,
the EPROM is erased and can be reprogrammed. The memory
cells utilize proven EPROM floating gate technology and
byte-wide intelligent programming algorithms.
The CY27C256 offers the advantage of lower power and superior
performance and programming yield. The EPROM cell
requires only 12.5V for the super voltage, and low current requirements
allow for gang programming. The EPROM cells
allow each memory location to be tested 100% because each
location is written into, erased, and repeatedly exercised prior
to encapsulation. Each EPROM is also tested for AC performance
to guarantee that after customer programming, the
product will meet both DC and AC specification limits.
Reading the CY27C256 is accomplished by placing active
LOW signals on OE and CE. The contents of the memory location
addressed by the address lines
