CY7C1019V33-10VC

The CY7C1018V33/CY7C1019V33 is a high-performance CMOS static RAM 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 CY7C1019V33-10VC 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 CY7C1019V33-10VC 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 CY7C1019V33-10VC is deselected (CE HIGH), the outputs are disabled (OE HIGH), or during a write operation (CE LOW, and WE LOW).

The CY7C1018V33 is available in a standard 300-mil-wide SOJ and CY7C1019V33 is available in a standard 400-mil-wide package. The CY7C1018V33 and CY7C1019V33 are functionally equivalent in all other respects.
