Introduction
®
®
The Atmel AT32UC3C-EK is an evaluation kit and development system for the Atmel AVR UC3
AT32UC3C0512C microcontroller.
As a development system, the board notably provides on-board memory, a USB communication interface,
CAN and LIN network interfaces, and the JTAG programming and debugging interface. The AT32UC3CEK also features expansion headers; one of these is the wireless expansion header (named WLESS
header on the PCB).

Hardware Description
This chapter presents the hardware blocks of the AT32UC3C-EK hardware design. Each hardware block
is described with:
•
•
•
•
An overview of the hardware block
A location in the schematics document
AT32UC3C-specific information (when relevant)
All possible hardware configurations of the block and available test points
In each block description, the components reference and schematic can be found in the AT32UC3C-EK
Schematics and Assembly bottom/top views.
3.1.
Power Supply
The power supply block of the AT32UC3C-EK is in charge of distributing power to all components of the
board.
Figure 3-1 AT32UC3C-EK Power Supply Logical View
3.1.1.
Overview
The AT32UC3C-EK can be powered from four different sources: 2x USB mini AB plug (5V input): labeled
"USB USER" (J21) and "USB VCP" (J27) and 2x external power supply J1 jack connector or the J2 2pins headers (DC 12V ±10%).
The AT32UC3C-EK will automatically switch to the more accurate power source if it senses voltage on it
(external power supply is defined as the more accurate power source, then VBUS from "USB VCP" and
the less accurate power source is VBUS from "USB USER").
These inputs go through an external 3.3V switch mode regulator which delivers supplies to the rest of the
board with a 3.3V voltage.
The power indicator LED green D3, labeled "POWER", indicates if the 3.3V from the external regulator is
present.
Refer to Configurations and Test Points on page 10 for a description of the possible hardware
configurations of the power supply block.

Hardware Configurations
The default hardware configuration of the power supply block implies that:
•
•
The power supply source is one of the 2x USB plugs, "USB USER" or "USB VCP", or the jack
header
•

Overview
The networking block supports both CAN and LIN interface:
•
•
The CAN transceivers are embedded on the UC3C-EK (U9 and U11) and termination resistors can
be used as bus configuration through 2-pin headers (J9 and J14). See Configurations and Test
Points on page 10. The physical connections of CAN bus are accessible through DB9 connectors
(J10 and J15).
The LIN transceivers are embedded on the UC3C-EK (U10 and U12). The master/slave
configurations are accessible through 2-pin headers (J12 and J17). The board supports also the
capability to be powered-up by LIN bus through 2 pin headers (J11 and J16). See Configurations
and Test Points on page 10. The physical connections of LIN bus are accessible through 3-pins
headers (J13 and J18).

Hardware Configuration
The terminal resistors are mounted by default. Remove jumpers on the 2-pins headers (J9 or J14) to
suppress this termination.
The default hardware configuration of the LIN block implies that two nodes are in master configuration.
Only remove jumpers on the 2-pins headers (J12 or J17) to switch the node in slave configuration.
Moreover, the board is by default powered by the LIN bus.
To suppress this feature, remove jumpers on the 2-pins headers (J11 or J16).

Programming and Debugging Interface
The Programming and Debugging Interface block of the Atmel AT32UC3C-EK provides the developer a
mean to debug an application running on the Atmel AT32UC3C0512C.

Overview
Figure 3-12 AT32UC3C-EK Programming and Debugging Interface Logical View
The main Programming and Debugging Interface of the AT32UC3C-EK is meant to program and debug
the Atmel AT32UC3C0512C. There are two debug interfaces implemented in the AT32UC3C0512C: the
JTAG interface accessible through the J24 connector and the NEXUS interface accessible through the
J23 connector.

Configuration and Test Points
Special Considerations for the NEXUS pins
On the Atmel AVR UC3 C series, the NEXUS pins are multiplexed with I/O lines. While using these
multiplexed NEXUS lines all normal peripheral activity on these lines are disabled. The user must make
sure that no external peripheral is blocking the NEXUS lines while debugging.

Table 3-16 Conflicts Conditions over the NEXUS Debugging Pins on page 23 highlights the
components of the Atmel AT32UC3C-EK that might interfere with the multiplexed NEXUS pins. These
components must not be used while debugging with the NEXUS interface.

Overview
Figure 3-14 AT32UC3C-EK Expansion Interface Logical View
There are three expansion headers on the Atmel AT32UC3C-EK:
•
•
•
The J25 header (labeled WLESS) to connect the wireless extension board to provide wireless
communication capabilities to the kit. Signals on J25.1 and J25.2 are configurable with the J44
header. The Atmel AT32UC3C0512C modules available on J25 are USART1 and SPI1; depending
on the J44 configuration, TWIMS0 is available too.
The J19 and J20 headers provide access to several GPIOs of the AT32UC3C0512C and ground
and VCC3.
The Atmel AVRMC300 expansion offers the possibility to connect an AVRMC300 expansion motor
control board:
–
–
•
The J33 header provides access to the power driver control signals (PWM signals)
The J38 header provides access to the current and back-EMF measurement (ADC and AC
signals)
– The J41 header provides access to Hall-Effect sensors (GPIO signals)
– The J43 header provides access to quadrature decoder sensors (QDEC signals)
Refer to Reference Materials on page 7 for more detailed information.

the J25 and J44 Headers on page 25 for a description of the possible configurations.
AVRMC300 Configuration
The XL and XH signals are multiplexed with NEXUS signals. Due to that, 0Ω resistors (R160 and R162)
are inserted between these signals and I/O signals. There are not mounted by default. It means NEXUS
signals are functional. Just mount these resistors to activate XL and XH signals.
The differential measures and comparator detections are multiplexed. Due to that, 0Ω resistors (R157,
R158, R159, and R161) are inserted. As there are mounted by default, differential measures and
comparator detections are accessible.
Test points
None.
Weaknesses

•
•
•
•
The touch sensors
The LEDs LED0-4
The 2x push-button
The RST push-button
The QVGA LCD Display

Configuration
A USB DFU Bootloader is pre-loaded on the Atmel AT32UC3C0512C. To enter this bootloader mode, the
PB0 push-button must be pressed upon reset then released. It is then possible to program the
AT32UC3C0512C through the USB DFU Bootloader.
