CY7C1021BN CY7C10211BN 1-Mbit 64K x 16 Static RAM • Temperature Ranges Commercial 0°C to 70°C Industrial to 85°C Automotive-A to 85°C Automotive-E to 125°C • High speed tAA = 10 ns Commercial tAA = 15 ns Automotive • CMOS for optimum speed/power • Low active power 825 mW max. • Automatic power-down when deselected • Independent control of upper and lower bits • Available in Pb free and non Pb free 44-pin TSOP II and 44-pin 400-mil-wide SOJ Functional Description[1] The CY7C1021BN/CY7C10211BN is a high-performance CMOS static RAM organized as 65,536 words by 16 bits. 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. If Byte Low Enable BLE is LOW, then data from I/O pins I/O1 through I/O8 , is written into the location specified on the address pins A0 through A15 . If Byte High Enable BHE is LOW, then data from I/O pins I/O9 through I/O16 is written into the location specified on the address pins A0 through A15 . Reading from the device is accomplished by taking Chip Enable CE and Output Enable OE LOW while forcing the Write Enable WE HIGH. If Byte Low Enable BLE is LOW, then data from the memory location specified by the address pins will appear on I/O1 to I/O8. If Byte High Enable BHE is LOW, then data from memory will appear on I/O9 to I/O16. See the truth table at the back of this data sheet for a complete description of read and write modes. The input/output pins I/O1 through I/O16 are placed in a high-impedance state when the device is deselected CE HIGH , the outputs are disabled OE HIGH , the BHE and BLE are disabled BHE, BLE HIGH , or during a write operation CE LOW, and WE LOW . The CY7C1021BN/CY7C10211BN is available in standard 44-pin TSOP Type II and 44-pin 400-mil-wide SOJ packages. Customers should use part number CY7C10211BN when ordering parts with 10 ns tAA, and CY7C1021BN when ordering 12 ns and 15 ns tAA.

Functional Description[1]

The CY7C1021BN/CY7C10211BN is a high-performance CMOS static RAM organized as 65,536 words by 16 bits. 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. If Byte Low Enable BLE is LOW, then data from I/O pins I/O1 through I/O8 , is written into the location specified on the address pins A0 through A15 . If Byte High Enable BHE is LOW, then data from I/O pins I/O9 through I/O16 is written into the location specified on the address pins A0 through A15 .

Reading from the device is accomplished by taking Chip Enable CE and Output Enable OE LOW while forcing the Write Enable WE HIGH. If Byte Low Enable BLE is LOW, then data from the memory location specified by the address pins will appear on I/O1 to I/O8. If Byte High Enable BHE is LOW, then data from memory will appear on I/O9 to I/O16. See the truth table at the back of this data sheet for a complete description of read and write modes.

The input/output pins I/O1 through I/O16 are placed in a high-impedance state when the device is deselected CE HIGH , the outputs are disabled OE HIGH , the BHE and BLE are disabled BHE, BLE HIGH , or during a write operation CE LOW, and WE LOW .
The CY7C1021BN/CY7C10211BN is available in standard 44-pin TSOP Type II and 44-pin 400-mil-wide SOJ packages. Customers should use part number CY7C10211BN when ordering parts with 10 ns tAA, and CY7C1021BN when ordering 12 ns and 15 ns tAA.
