Functional Description

The CY62128EV30 module organized as 128K 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 applications such as cellular telephones. 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 (CE input and output pins (IO impedance state when the device is deselected (CE CE
LOW), the outputs are disabled (OE HIGH), or a write
2
operation is in progress (CE LOW).
To write to the device, take Chip Enable (CE HIGH) and Write Enable (WE) inputs LOW. Data on the eight IO pins is then written into the location specified on the Address pin (A0 through A16).
To read from the device, take Chip Enable (CE1 LOW and CE HIGH) and Output Enable (OE) LOW while forcing Write Enable (WE
) HIGH. Under these conditions, the contents of the memory
location specified by the address pins appear on the IO pins.
