• Available in Pb-free 48-ball VFBGA package

Functional Description[1]

The CY62167DV18 is a high performance CMOS static RAM organized as 1M words by 16 bits. This device features advanced circuit design to provide ultra low active current. This is ideal for providing More Battery Life in portable applications such as cellular telephones. The device also has an automatic power down feature that significantly reduces power consumption by 99% when addresses are not toggling. Placing the device into standby mode reduces power

Logic Block Diagram
consumption by more than 99% when deselected CE1 HIGH or CE2 LOW or both BHE and BLE are HIGH . The input and output pins IO0 through IO15 are placed in a high impedance state when:
• Deselected CE1 HIGH or CE2 LOW
• Outputs are disabled OE HIGH
• Both Byte High Enable BHE and Byte Low Enable BLE are disabled BHE, BLE HIGH
• Write operation is active CE1 LOW, CE2 HIGH and WE LOW

To write to the device, take Chip Enables CE1 LOW and CE2 HIGH and Write Enable WE input LOW. If BLE is LOW, then data from IO pins IO0 through IO7 is written into the location specified on the address pins A0 through A19 . If BHE is LOW then data from IO pins IO8 through IO15 is written into the location specified on the address pins A0 through A19 . To read from the device, take Chip Enables CE1 LOW and CE2 HIGH and OE LOW while forcing the WE HIGH. If BLE is LOW, then data from the memory location specified by the address pins appear on IO0 to IO7. If BHE is LOW, then data from memory appears on IO8 to IO15. See the “Truth Table” on page 9 for a complete description of read and write modes.
