CY62167DV30LL-55BVXI

The CY62167DV30is 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 (MoBL) 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. The device can also be put into standby mode when deselected. The input/output pins are placed in a high-impedance state when: deselected, outputs are disabled, both Byte High Enable and Byte Low Enable are disabled, or during a Write operation. Writing to the device is accomplished by taking Chip Enables and Write Enable input LOW. If Byte Low Enable is LOW, then data from I/O pins, is written into the location specified on the address pins. If Byte High Enable is LOW, then data from I/O pins is written into the location specified on the address pins. Reading from the device is accomplished by taking Chip Enables and Output Enable LOW while forcing the Write Enable HIGH. If Byte Low Enable is LOW, then data from the memory location specified by the address pins appear on I/O0 to I/O7. If Byte High Enable is LOW, then data from memory appear on I/O8 to I/O15. See the truth table at the back of this data sheet for a complete description of Read and Write modes.
