CY7C1041BV33

The CY7C1041BV33 is a high-performance CMOS Static RAM organized as 262,144 words by 16 bits.

Writing to CY7C1041BV33 is accomplished by taking Chip Enable (CE) and Write Enable (WE) inputs LOW. If Byte Low Enable (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, then data from I/O pins (I/O₈ through I/O₁₅)CY7C1041BV33  is written into the location specified on the address pins (A₀ through A₁₇).

Reading from CY7C1041BV33 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 address pins ofCY7C1041BV33 will appear on I/O₀ to I/O₇. If Byte High Enable (BHE) is LOW, then data from memory will appear on I/O₈ to I/O₁₅. See the truth table at the back of this data sheet for a complete description of read and write modes.

The input/output pins (I/O0 through I/O15) are placed in a high-impedance state when CY7C1041BV33 is deselected (CE HIGH), 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 CY7C1041BV33 is available in a standard 44-pin 400-mil-wide body width SOJ and 44-pin TSOP II package with center power and ground (revolutionary) pinout.
