The CY62177EV30LL-55ZXI is a high performance CMOS static RAM organized as 2 M words by 16 bits and 4 M words by 8 bits[1]. This device features advanced circuit design to provide ultra low active current. It 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 percent 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 and output pins (I/O0 through I/O15) are placed in a high impedance state when: deselected (CE1HIGH 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).
