Functional Description
The CY62148EV30 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 such as cellular telephones. The device also has an
automatic power down feature that significantly reduces power
consumption. Placing the device into 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).
To write to the device, take Chip Enable (CE) and Write Enable
(WE) inputs LOW. Data on the eight I/O pins (I/O0 through I/O7)
is then written into the location specified on the address pins (A0
through A18).
To read from the device, take Chip Enable (CE) 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 I/O pins.
