Functional Description^[1]

The CY62136V is a high-performance CMOS static RAM organized as 128K 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 (CE HIGH). The input/output pins (I/O0 through I/O 15) are placed in a high-impedance state when: deselected (CE HIGH), outputs are disabled (OE HIGH), BHE and BLE are disabled (BHE, BLE HIGH), or during a write operation (CE LOW, and WE LOW).
