WCFS0808V1E

The WCFS0808V1E is a high-performance 3.3V CMOS Static RAM organized as 32K words by 8 bits. Easy memory expansion is provided by an active LOW Chip Enable (CE) and active LOW Output Enable (OE) and three-state drivers. The WCFS0808V1E 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 of WCFS0808V1E on the eight data input/output pins (I/O0 through I/O7) is written into the memory location addressed by the address present on the address pins (A0 through A14).

Reading the WCFS0808V1E 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 contents of the location addressed by the information on address pins is present on the eight data input/output pins.

The input/output pins of WCFS0808V1E 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 standard 300-mil-wide SOJ and TSOP Type I packages.
