Infineon/CYPRESS CY62148ESL-55ZAXA

The CY62148ESL is a high performance CMOS static RAM organized as 512K words by 8-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. The device also has an automatic power-down feature that significantly reduces power consumption. Placing the device in standby mode reduces power consumption by more than 99 percent when deselected (CE HIGH). The eight input and output pins I/O₀ through I/O₇ are placed in a high impedance state when the device is deselected (CE HIGH), the outputs are disabled (OE HIGH), or during a write operation (CE LOW and WE LOW).
