Functional Description
The CY62148DV30 [1] 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. The device can be put into standby mode reducing
power consumption when deselected (CE HIGH).The eight input
and output pins (I/O0 through I/O7) are placed in a
high-impedance state when:
Deselected (CE HIGH)
Outputs are disabled (OE HIGH)
When the write operation is active(CE LOW and WE LOW)
Write to the device by taking 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).
Read from the device by taking 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 will appear on the I/O pins.
