Features
Functional Description
The CY62146CV30 is a high-performance CMOS static RAM
organized as 256K words by 16 bits. This device features ad-
vanced 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
• High speed:
• Voltage range:
• Pin compatible with CY62146V
• Ultra-low active power
• Low standby power
• Easy memory expansion with CE and OE features
• Automatic power-down when deselected
• CMOS for optimum speed/power

The device can also be put into standby mode reducing power
consumption by 99% when deselected (CE HIGH). The in-
put/output pins (I/O
state when: deselected (CE HIGH), outputs are disabled (OE
HIGH), both Byte High Enable and Byte Low Enable are dis-
abled (BHE, BLE HIGH), or during a Write operation (CE LOW
and WE LOW).
Writing to the device is accomplished by taking Chip Enable

Reading from the device is accomplished by taking Chip En-
able (CE) and Output Enable (OE) LOW while forcing the Write
Enable (WE) HIGH. If Byte Low Enable (BLE) is LOW, then
data from the memory location specified by the address pins
will appear on I/O
