CY7C1019B-10VC

The CY7C1019B/10191B is a high-performance CMOS staticRAM organized as 131,072 words by 8 bits. Easy memory expansion is provided by an active LOW Chip Enable (CE), an active LOW Output Enable (OE), and three-state drivers. This device has an automatic power-down feature that significantly reduces power consumption when deselected.

Writing to the device is accomplished by taking Chip Enable (CE) and Write Enable (WE) inputs LOW. 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 (CE) and Output Enable (OE) LOW while forcing Write Enable (WE) 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 (CEHIGH), the outputs are disabled (OE HIGH), or during a write operation (CE LOW, and WE LOW).

The CY7C1019B/10191B is available in standard 32-pin TSOP Type II and 400-mil-wide SOJ packages. Customers should use part number CY7C10191B when ordering parts with 10 ns tAA, and CY7C1019B when ordering 12 and 15 ns tAA.
