See Figure 1, 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 Power Supply.
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 User Interface.
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 Programming and Debug Interface.
The AT32UC3L064 has access to one external on-board Atmel DataFlash 64Mb memory. For a detailed presentation of the external memory block, see Section External Memory.
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, see Section Real Time Clock.
The expansion interface offers the possibility to connect various external devices to the AT32UC3L064. The J8 header (labeled WLESS on the PCB) connects the RZ600 AT86RF231 radio board (provided with this board) to provide wireless capabilities to the kit. Obviously, dedicated firmware must be running on the AT32UC3L064 to support this feature. The J14 and J15 headers provide access to all of the AT32UC3L064's GPIOs. For a detailed presentation of the expansion interface block, see Section Expansion Interface.
To provide USB communication capabilities to the kit, the AT32UC3L064 accesses the USB interface block through the USART3 RX and TX signals. The USB interface block main component is the AT32UC3B1256 device, pre-loaded with several default firmware components providing added features to the kit. For a detailed presentation of the USB interface block, see Section USB Interface.
