Functional Description
[2]
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% when
deselected (CE HIGH). The eight input and output pins (IO
0
through IO
7
) 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 IO pins (IO
0
through IO
7
)
is then written into the location specified on the address pins
(A
0
through A
18
).
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 IO pins.
Notes
1. SOIC package is available only in 55 ns speed bin.
