CY7C1049B • High speed tAA = 12 ns • Low active power 1320 mW max. • Low CMOS standby power Commercial L version mW max. • 2.0V Data Retention 400 µW at 2.0V retention • Automatic power-down when deselected • TTL-compatible inputs and outputs • Easy memory expansion with CE and OE features • Available in Pb-free and non Pb-free 36-Lead 400-Mil Molded SOJ Logic Block Diagram A0 A1 A2 A3 A4 A5 A6 A7 A8 A9 A10 INPUT BUFFER 512K x 8 ARRAY COLUMN DECODER POWER DOWN 512K x 8 Static RAM Functional Description[1] The CY7C1049B is a high-performance CMOS static RAM organized as 524,288 words by 8 bits. Easy memory expansion is provided by an active LOW Chip Enable CE , an active LOW Output Enable OE , and tri-state drivers. 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 A18 . 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 .

Functional Description[1]

The CY7C1049B is a high-performance CMOS static RAM organized as 524,288 words by 8 bits. Easy memory expansion is provided by an active LOW Chip Enable CE , an active LOW Output Enable OE , and tri-state drivers. 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 A18 .

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 .
