WCMA1008U1X

The WCMA1008U1X is a high-performance CMOS static RAM organized as 128K words by 8 bits. Easy memory expansion is provided by an active LOW Chip Enable (CE₁), an active  HIGH Chip Enable (CE₂), an active LOW Output Enable (OE) and three-state drivers. WCMA1008U1X has an automatic power-down feature, reducing the power consumption by over 99% when deselected.

Writing to the device  is accomplished by taking Chip Enable one (CE₁) and Write Enable (WE) inputs LOW and the Chip
Enable two (CE₂) input HIGH. Data on the eight I/O pins (I/O0 through I/O7) is then written into the location specified on the address pins (A0 through A16).

Reading from the device  is accomplished by taking Chip Enable one (CE₁) and Output Enable (OE) LOW while forcing Write Enable (WE) and Chip Enable two (CE₂) HIGH. Under these conditions, the contents of the memory location specified by the address pins will appear on the I/O pins.The eight input/output pins (I/O0 through I/O7) are placed in a high-impedance state when the device is deselected (CE₁ HIGH or CE₂ LOW), the outputs are disabled (OE HIGH), or
during a write operation (CE₁ LOW, CE₂ HIGH, and WE LOW).

The WCMA1008U1X is available in a 32 Lead TSOP and STSOP packages.
