3 General information

This document targets the Atmel AT32UC3L064 evaluation kit revision 4, and parts of

the document may, therefore, be inconsistent with earlier revisions of the product. For

earlier revisions, please refer to the schematics, which is the only documentation

available for these revisions. The Atmel UC3-L0 Xplained kit is intended to

demonstrate the AT32UC3L064 microcontroller, and the hardware that relates to the

Atmel AT32UC3B1256 (board controller) is, therefore, not covered in detail in this

document.

USB Device

3.1 Preprogrammed firmware

The Atmel AT32UC3L064 and the Atmel AT32UC3B1256 that come with the Atmel

UC3-L0 Xplained kit are both preprogrammed.

The preprogrammed firmware in the AT32UC3L064 is set up with a small demo with

the Atmel QMatrix touch slider and Atmel QTouch button that can be used to control

the RGB LED. The device also features a UART boot loader that can be used to

program new firmware to the device. Hold the mechanical button while applying

power to start the boot loader. The boot loader can be used with the command line

tool “batchISP” delivered with FLIP.

The preprogrammed AT32UC3B1256 firmware offers features such as a boot loader

for self-programming of the board controller itself and a UART-to-USB gateway. The

bootloader can be started by shorting the 2-pin header (not mounted) while applying

power to the board. The bootloader can be used with the command line tool

“batchISP” delivered with FLIP.

32156A-AVR-01/11

3.2 Power supply

The kit is powered via the USB connector, which leaves two options to power it:

Connect the kit either to a PC through a USB cable or to a 5V USB power supply

(AC/DC adapter).

The 5V is regulated down to 3.3V with an onboard LDO regulator, which provides

power to the entire board. The Atmel AT32UC3L064 is powered by 3.3V, but if 1.8V

operation is desired, some modifications to the board are needed. This includes

replacing the regulator with one that delivers 1.8V output and rerouting the power to

the device (see schematic for explanation). As some of the other ICs on the Atmel

UC3-L0 Xplained require 3.3V to operate correctly, these devices have to be removed

also.

3.3 Measuring the AT32UC3L064 power consumption

As part of an evaluation of the AT32UC3L064, it can be of interest to measure its

power consumption. The two-pin header with a jumper mounted on it is the only

connection between the common power plane VCC_P3V3 and the VCC_MCU_P3V3

power plane. By replacing the jumper with an ampere meter, it is possible to

determine the current consumption of the AT32UC3L064. To locate the power

measurement header, please refer to Figure 3-1.

WARNING

Do not power the board without having the jumper or an ampere meter

mounted. Otherwise, the device may be damaged.

3.4 Programming the AT32UC3L064 through the UART-to-USB gateway

The AT32UC3L064 can be programmed through the UART-to-USB gateway. This

can be accomplished using the UART boot loader preprogrammed in the device.

Press and hold the mechanical button switch while powering up the board to enter the

boot loader, and use 32-bit AVR Studio to set up a programming connection to the

device.

NOTE

If the default board controller firmware is replaced, programming of the

AT32UC3L064 may not be possible as the UART-to-USB functionality might be

missing.

If any external programming tool is used on the AT32UC3L064, the boot loader might

be erased, and it will not be possible to program the device through the UART-to-USB

gateway. In this case the boot loader has to be restored with an external

programming tool.

3.5 Communication through the UART-to-USB gateway

The AT32UC3L064 UART is connected to a UART on the Atmel AT32UC3B1256.

The AT32UC3B1256 UART is communicating at 57600 baud, using one start bit,

eight data bits, one stop bit, and no parity.

When the AT32UC3B1256 device is enumerated (connected to a PC), the data

transmitted from the AT32UC3L064 is passed on to a (virtual) COM port. This means

that it is possible to use a terminal program to receive the transmitted data on a PC.

Similarly data transmitted from the PC COM port is passed on to the AT32UC3L064

UART through the gateway.

4 Connectors

The Atmel UC3-L0 Xplained kit has five 10-pin, 100mil headers. Two headers have a

fixed communication interface (J1 and J4). One header has analog functionality (J2),

and the last header (J3) has general purpose digital I/O.

The 90° angled header is the JTAG programming and debugging header for the

AT32UC3L064.

For the location of the respective headers, refer to Figure 3-1.

4.1 Programming headers

The Atmel AT32UC3L064 can be programmed and debugged by connecting an

external programming/debugging tool to the JTAG header. The header has a

standard JTAG programmer pinout (refer to online help in AVR Studio), and tools

such as JTAGICE mkII or AVR ONE! can thus be connected directly to the header.

NOTE

The grey female 10-pin header on JTAGICE mkII has to be used when connecting to

the kit. A scoring in the board is made to fit the orientation tab on the header.

A standoff adapter (no. 1) is needed Pin 1 on the JTAG header is at the top right

corner. This is rotated 180° compared to the other headers (J1, J2, J3, and J4).J1, J2,

J3, and J4).

1. Standard pinout for JTAGICE mkII and other Atmel programming tools.

Note:

The Atmel AT32UC3B1256 can be programmed through its boot loader. The boot

loader is evoked by shorting the two holes close to the device before applying power

to the board. The two holes have 100mil spacing, so the user can solder in a two-pin

header and use a jumper to easily enter the boot loader. Programming is performed

through the boot loader programmer target in the Atmel AVR32 Studio.

Alternatively, the AT32UC3B1256 can also be programmed by connecting a

programming tool, such as JTAGICE mkII, to the 10-pin test points on the bottom side

of the board (marked with BC JTAG).

NOTE

It is not recommended to program the AT32UC3B1256 using a programming tool, as

this will erase the boot loader.

32156A-AVR-01/11

4.2 I/O expansion headers

There are four available I/O expansion headers on the kit. Because of the low pin

count on the device, the I/O expansion header pins are shared with onboard

functionality. If “clean” expansion ports are needed, cut-straps are available on some

of the ADC inputs. Otherwise, it is only needed to remove a series resistor to remove

onboard functionality. Table 4-2 show what is shared on the respective header pins.

5 Memories

The Atmel UC3-L0 Xplained does not have any external memories mounted on the

board. Footprints are available for adding either an industrial standard or a proprietary

Atmel DataFlash serial flash.

NOTE

The footprints share the same SPI lines, including the chip select, and so it is not

possible to mount a device on both footprints at the same time.

6 Miscellaneous I/O

6.1 Mechanical button switch

The board is equipped with one mechanical button switch. The button is shared with

LED0, and onboard protection circuitry is added to avoid a short when driving the port

high at the same time as pushing the button, which will short it to ground. To be able

to use both button and LED, time multiplexing has to be used.

To be able to detect a button press, the firmware has to periodically set the I/O pin to

input with pull-up and check if it is low. When done fast enough, the human eye will

not see any change on the LED.

6.2 LEDs

The Atmel UC3-L0 Xplained has three LEDs mounted onboard that are connected to

the Atmel AT32UC3L064. These include two standard yellow LEDs and one RGB

LED. The two yellow LEDs are active low, while the RGB LED is active high.

LED0 is shared with the mechanical button. When turning this LED on, set the I/O pin

to output low. When turning the LED off, set the I/O pin as input with pull-up. When

the LED is turned on, the protection circuitry added to the button will make the LED

shine brighter when the button is pressed. When the LED is off, any button press will

light up the LED.

One additional dual LED is mounted near the USB connector. This is the power and

status LED, which is connected to the board controller. This LED will be green when

power is applied, and will toggle between green and orange when communication

over USB is ongoing.

6.3 Analog I/O

A RC filter and an NTC are connected to ADC0 and ADC4 respectively. These analog

references can be used as input to the ADC. Both analog references can be

disconnected by cutting the cut-straps on the bottom side of the board.

The RC filter (1^storder low-pass) has an approximate 3dB cut-off frequency of 160Hz.

The input to the RC filter is one of the UC3 GPIO pins that can be configured to

output a PWM signal to the RC filter. This can be used to generate a DC voltage on

the output of the RC filter, which can be measured on the ADC. As this is a 1^storder

filter, the ripple on the DC voltage is proportional to the input frequency. A higher

input frequency will give lower ripple on the output.

6.4 Touch

The UC3-L0 Xplained kit has one Atmel QTouch button and one Atmel QMatrix slider

implemented onboard. The button and the slider are connected to the built-in CAT

module in the AT32UC3L064.

The QMatrix slider can be reconfigured to be used as four separate buttons instead of

as a slider.

NOTE

As the device has a very low pin count, a tradeoff has been made to be able to have

as many I/O lines as possible routed to the headers. The sensor lines to the Atmel

QTouch button and the Atmel QMatrix slider are shared with some of the headers.

The sensitivity of the sensor lines is very high on these exposed pins, and so touching

the I/O pins will give erroneous result in the touch sensing mechanism.

NOTE

Adding top modules to the board with functionality connected to these pins is not

recommended. Top modules without functionality on these pins will only add some

capacitive load and will not affect the QMatrix sensor significantly.

6.5 Board controller

The board controller and the Atmel AT32UC3L064 are connected together through

TWI and UART. Both interfaces can be used to communicate between the devices,

but only the UART is implemented by default in the board controller.

7.1 Compiling and running

The code examples that can be found in ASF can be compiled by running make on

the makefile included in the project or by opening the project in IAR™ and compiling

the project within IAR.

8 Known Issues

8.1 Light sensor

The output range on the light sensor is 0V – 3.3V. The ADC reference must therefore

be high enough to match the output range of the light sensor when doing

measurements.

8.2 USB test points

Touching the test points for the USB data lines on the back side of the board while

there is ongoing communication might interrupt the device and cause the device to

stop responding. The kit must be reconnected to start working properly again.
