SCANSTA476 Eight Input IEEE 1149.1 Analog Voltage Monitor  
Check for Samples: SCANSTA476  
1
FEATURES  
DESCRIPTION  
The SCANSTA476 is a low power, Analog Voltage  
Monitor used for sampling or monitoring up to 8  
analog/mixed-signal input channels. Analog Voltage  
Monitors are valuable during product development,  
environmental test, production, and field service for  
verifying and monitoring power supply and reference  
voltages. In a supervisory role, the 'STA476 is useful  
for card or system-level health monitoring and  
prognostics applications.

Eight Selectable Analog Input Channels  
Analog Full-Scale Input Range 0V to VDD  
Typical Accuracy of 2 mV at Maximum VDD  
Very Low Power Operation  
Small Package Footprint in 16-Lead, 5 x 5 x 0.8  
mm WSON  
Single +2.7V to +5.5V Supply Operation  
IEEE 1149.1 (JTAG) Compliant Interface  
Instead of requiring an external microcontroller with a  
GPIO interface, the 'STA476 features a common  
IEEE 1149.1 (JTAG) interface to select the analog  
input, initiate a measurement, and access the results  
- further extending the capabilities of an existing  
JTAG infrastructure.  
APPLICATIONS  
Measurement of Point Voltages  
Real-time Signal Monitoring  
System Health Monitoring and Prognostics  
The SCANSTA476 uses the VREF input as  
a
Debug, Environmental Test, Production Test,  
Field Service  
reference. This enables the SCANSTA476 to operate  
with a full-scale input range of 0 to VDD, which can  
range from +2.7V to +5.5V.  
Supplement In-Circuit Tester (ICT) Access  
Vital in Servers, Computing,  
Telecommunication and Industrial Equipment  
The SCANSTA476 is packaged in a 16-lead non-  
pullback WSON package that provides an extremely  
small footprint for applications where space is a  
critical consideration. This product operates over the  
industrial temperature range of 40°C to +85°C.
