LOW-VOLTAGE 1-WIRE DIGITAL TEMPERATURE SENSOR

PRODUCT SPECIFICATION

Pin Configuration

Product Description

The aSC7521A is a high-precision CMOS temperature sensor

and voltage monitor with Simple Serial Transport (SST)

compatible serial digital interface, intended for use in PC

hardware monitor applications.

Communication of device capabilities and temperature

readings takes place over the high-speed bi-directional SST

interface.

V_DD

SST

The SST temperature sensor provides a means for an analog

signal to travel over a digital bus enabling remote temperature

sensing in areas previously not monitored in the PC. The

temperature sensor supports an internal and external thermal

diode.

Sensor localization is aided by two address pins that

distinguish multiple sensors on the same bus.

The aSC7521A is available in MSOP-8 surface mount

package.
