CY62148ELL-45ZSXIT

CY62148ELL-45ZSXIT is a high performance CMOS static RAM organized as 512K words by 8-bits. This device features an advanced circuit design to provide ultra-low standby 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 when addresses are not toggling. Placing the device into standby mode reduces power consumption by more than 99% when deselected (active-low 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 (active-low CE HIGH), outputs are disabled (active-low OE HIGH), or during an active write operation (active-low CE LOW and active-low WE LOW). It is suitable for interfacing with processors that have TTL I/P levels.
