WCFS4016V1C

The WCFS4016V1C is high-performance CMOS Static RAMs organized as 262K words by 16 bits.

Writing to the WCFS4016V1C is accomplished by taking Chip Enable(CE) and Write Enable (WE) inputs LOW. If Byte Low nable (BLE) is LOW, then data from I/O pins (I/O₀ through I/O₇ ), is written into the location specified on the address pins A₀ through A₁₇ ). If Byte High Enable (BHE) is LOW, from I/O pins of WCFS4016V1C (I/O₈ then data through I/O₁₅ ) is written into the locati specified on the address pins (A ₀ on through A ₁₇).

Reading from the WCFS4016V1C is accomplished by taking Chip Enable (CE) and Output Enable (OE) LOW while forcing the Write Enable (WE) HIGH. If Byte Low Enable (BLE) is LOW, then data from the memory location specified by the dress pins will appear on I/O₀ to I/O₇ . If Byte High Enable (BHE) is. See LOW, then data from memory will appear on I/O₈ to I/O₁₅ the truth table at the back of this data sheet for a complete description of read and write modes.

The input/output pins of WCFS4016V1C (I/O₀ through I/O₁₅ ) are placed in a high-impedance state when the device is deselected (CEHIG H), the outputs are disabled (OE HIGH), the BHE and BLE are disabled (BHE, BLE HIGH), or during a write operation (CE LOW, and WE LOW).

The WCFS4016V1C is available in a standard 44-pin 400-mil-wide body width SOJ and 44-pin TSOP II package with cen
ter power and ground pinout.
