Functional Description

The CY7C1021CV33 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 IO pins IO1 through IO8 , is written into the location specified on the address pins A0 through A15 . If Byte High Enable BHE is LOW, then data from IO pins IO9 through IO16 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 appear on IO1 to IO8. If Byte High Enable BHE is LOW, then data from memory appears on IO9 to IO16. For more information, see the “Truth Table” on page 9 for a complete description of Read and Write modes.

The input and output pins IO1 through IO16 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 .

For best practice recommendations, refer to the Cypress application note AN1064, SRAM System Guidelines.
