009B CY7C109B CY7C1009B 128K x 8 Static RAM A9 A 10 A 11 A12 A13 A14 A15 A16 • High speed tAA = 12 ns • Low active power 495 mW max. 12 ns • Low CMOS standby power 55 mW max. 4 mW • 2.0V Data Retention • Automatic power-down when deselected • TTL-compatible inputs and outputs • Easy memory expansion with CE1, CE2, and OE options Functional Description The CY7C109B / CY7C1009B 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 CE1 , an active HIGH Chip Enable CE2 , an active LOW Out- Logic Block Diagram A0 A1 A2 A3 A4 A5 A6 A7 A8 CE1 CE2 WE ROW DECODER SENSE AMPS INPUT BUFFER 512 x 256 x 8 ARRAY COLUMN DECODER POWER DOWN put Enable OE , and three-state drivers. Writing to the device is accomplished by taking Chip Enable One CE1 and Write Enable WE inputs LOW and Chip Enable Two CE2 input HIGH. 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 One CE1 and Output Enable OE LOW while forcing Write Enable WE and Chip Enable Two CE2 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 CE1 HIGH or CE2 LOW , the outputs are disabled OE HIGH , or during a write operation CE1 LOW, CE2 HIGH, and WE LOW . The CY7C109B is available in standard 400-mil-wide SOJ and 32-pin TSOP type I packages. The CY7C1009B is available in a 300-mil-wide SOJ package. The CY7C1009B and CY7C109B are functionally equivalent in all other respects.
