Features

Functional Description

The CY62148V is a high-performance CMOS static RAM

organized as 512K words by eight bits. This device features

advanced circuit design to provide ultra-low active current.

This is ideal for providing More Battery Life

portable applications such as cellular telephones. The device

• Wide voltage range: 2.7V–3.6V

• Ultra low active power

• Low standby power

• TTL-compatible inputs and outputs

• Automatic power-down when deselected

• CMOS for optimum speed/power

• Package available in a 32 pin TSOPII and a 32-pin SOIC

also has an automatic power-down feature that significantly

reduces power consumption by 99% when addresses are not

toggling. The device can be put into standby mode when

deselected (CE HIGH).

Writing to the device is accomplished by taking Chip Enable

(CE) and Write Enable (WE) inputs LOW. Data on the eight I/O

Reading from the device is accomplished 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.

The eight input/output pins (I/O
