Atmel MCU Evaluation Kit AT32UC3L-EK AT32UC3L-EK Data Sheet

 

32150B-AVR-03/12 

A few test points covering the power supply block have been placed on the Atmel 
AT32UC3L-EK for the verification of important signals. 

Table 3-2. Power supply block test points. 

TP7 

Input voltage level after D1 when the J2 external power supply is used 

TP8 

Input voltage for all boards’ components except the Atmel AT32UC3L064. 
Should be 3.3V nominal 

TP9 

Input voltage for the AT32UC3L064 VDDIO pin. Should be 3.3V nominal 

TP10 

Output voltage out of the external regulator 

TP11 

Input voltage for the AT32UC3L064 VDDIN pin. Should be 3.3V nominal 

TP12 GND

To measure the power consumption of the overall board minus the AT32UC3L064, 
remove the 0Ω R11 resistor and measure the current over the J4 2-pin header (not 
mounted by default). 

To measure the power consumption on the AT32UC3L064 VDDIO, remove the 0Ω 
R14 resistor and measure the current over the J5 2-pin header (not mounted by 
default). 

To measure the power consumption on the AT32UC3L064 VDDIN, remove the 0Ω 
R19 resistor and measure the current over the J6 2-pin header (not mounted by 
default).
