Part#: CY7C271A-25JC
Part Category: Memory ICs

Manufacturer: Cypress Semiconductor Corp.

Description: OTP ROM, 32KX8, 25ns, CMOS, PQCC32

The CY7C271A is a high-performance 32,768-word by 8-bit
CMOS PROM. When disabled (CE HIGH), the 7C271A
automatically powers down into a low-power stand-by mode.
The CY7C271A is packaged in the 300-mil slim package and
is available in a cerDIP package equipped with an erasure
window to provide for reprogrammability. When exposed to UV
light, the PROM is erased and can be reprogrammed. The
memory cells utilize proven EPROM floating gate technology
and byte-wide intelligent programming algorithms.
The CY7C271A offers the advantages of lower power,
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 PROM is also tested for AC performance to guarantee that after customer programming, the
product will meet DC and AC specification limits.
Reading the 7C271A is accomplished by placing active LOW
signals on CS1 and CE, and an active HIGH on CS2. The
contents of the memory location addressed by the address
lines (A0–A14) will become available on the output lines
(O0–O7).
