aSC7521A
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.
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.
