Functional Description
The CY62148DV30 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
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 (IO
are placed in a high-impedance state when:
Write to the device by taking Chip Enable (CE) and Write
Enable (WE) inputs LOW. Data on the eight IO pins (IO
through IO
address pins (A
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 IO pins.
• Deselected (CE HIGH)
• Outputs are disabled (OE HIGH)
• When the write operation is active(CE LOW and WE LOW)
