The AT32UC3L064 is the central point of the Atmel AT32UC3L-EK. 

See 

, for a logical view of the 

AT32UC3L064 in the kit. 

The AT32UC3L064 is powered from the power supply block. It can read the current 
battery voltage (through an ADCIFB channel), and may control the power supply 
block through the Power-Off signal. For a detailed presentation of the power supply 
block, see Section 

The AT32UC3L064 is in charge of the main user interface block: 

•  The touch sensors 
•  The LEDs LED0-4 
•  The WAKE pushbutton 
•  The RST pushbutton 
•  The three-axis accelerometer 
For a detailed presentation of the user interface block, see Section 

The AT32UC3L064 can be programmed and debugged through the programming and 
debugging interface block that provides JTAG or aWire access. For a detailed 
presentation of the programming and debugging interface block, see Section 

, 

The AT32UC3L064 has access to one external on-board Atmel DataFlash 64Mbit 
memory. For a detailed presentation of the external memory block, see Section 

, 

. 

A 32kHz crystal is connected to the AT32UC3L064 to support the lowest sleep 
modes, and to provide the RTC feature. For a detailed presentation of the RTC block,
