Functional Description
The WCFS0808V1E is a high-performance 3.3V CMOS Static
RAM organized as 32K words by 8 bits. Easy memory expan-
sion is provided by an active LOW Chip Enable (CE) and ac-
tive LOW Output Enable (OE) and three-state drivers. The de-
vice has an automatic power-down feature, reducing the
power consumption by more than 95% when deselected.
An active LOW Write Enable signal (WE) controls the writing/
reading operation of the memory. When CE and WE inputs are
both LOW, data on the eight data input/output pins (I/O
0
through I/O
7
) is written into the memory location addressed by
the address present on the address pins (A
0
through A
14
).
Reading the device is accomplished by selecting the device
and enabling the outputs, CE and OE active LOW, while WE
remains inactive or HIGH. Under these conditions, the con-
tents of the location addressed by the information on address
pins is present on the eight data input/output pins.
The input/output pins remain in a high-impedance state unless
the chip is selected, outputs are enabled, and Write Enable
(WE) is HIGH. The WCFS0808V1E is available in 28-pin stan-
dard 300-mil-wide SOJ and TSOP Type I packages.
