The CY62167DV30 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 (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 (CE1 HIGH or CE2 LOW or both BHE and BLE are
HIGH). The input/output pins (I/O0 through I/O15) are placed
in a high-impedance state when: deselected (CE1 HIGH or
CE2 LOW), outputs are disabled (OE HIGH), both Byte High
Enable and Byte Low Enable are disabled (BHE, BLE HIGH),
or during a Write operation (CE1 LOW, CE2 HIGH and WE
LOW).
