Fully Released Specification

PRODUCT SPECIFICATION

Product Description

The aSC7511 is a high-precision CMOS temperature

sensor with SMBus compatible serial digital interface,

intended for use in PC thermal management applications.

The aSC7511 can measure temperature of a remote

thermal diode to an accuracy of ±1°C. Internal temperature

can be measured to ±3°C.

Communication of configuration, temperature and alarm

status takes place over the PC standard System

Management Bus (SMBus).

The aSC7511 features thermal alarm functions with a user-

programmable trip and turn-off temperatures. The THERM

output comparator can be set to control a fan while

ALERT signals that the remote or local temperature is

outside of a range of temperatures. ALERT pin may be

optionally configured as a second THERM output,

THERM2 , controlling a second fan.

The aSC7511 is available in SOP-8 and MSOP-8 surface

mount packages.

Features

• Local and remote temperature sensors

• 0.25°C resolution, ±1°C accuracy on remote diode

• 1°C resolution, ±3°C accuracy on local sensor

• Extended temperature measurement range 0°C to

+127°C (default) or –55°C to +150°C

• 2-wire SMBus serial interface with SMBus alert

• Programmable over / under temperature limits

• Offset registers for system calibration

• One or two over-temperature fail-safe THERM

outputs

• 8-lead, Pb-free, SOIC (SOP) or MSOP package
