CY7C1019B CY7C10191B 128K x 8 Static RAM • High speed tAA = 10, 12, 15 ns • CMOS for optimum speed/power • Center power/ground pinout • Automatic power-down when deselected • Easy memory expansion with CE and OE options • Functionally equivalent to CY7C1019 Functional Description The CY7C1019B/10191B 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. Logic Block Diagram 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 CE HIGH , 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.
