Breakout Board mit dem ATXmega128A1, das Board kommt fertig bestückt.
Technische Daten und vollständige Englische Beschreibung:
This is a breakout board for
the 100-pin TQFP package of Atmel's ATxmega128A1. The ATxmega128A1 is a
low power, high performance and peripheral rich CMOS 8/16-bit
microcontroller based on the AVR enhanced RISC architecture.
Among the chip's many features are 128kB of flash memory, 8 kB SRAM, 78
I/O pins, eight 16-bit timers, sixteen 12-bit ADCs, four 12-bit DACs,
eight USART, four SPI and four TWI interfaces. This powerful chip can
process up to 32 MIPS when running at its maximum clock speed of 32MHz.
The operating voltage of the xmega is 1.6 to 3.6VDC.
All VCC pins of the ATxmega128A1 are connected together and brought out
to a single header pin, same goes for the GND and AVCC pins of the
chip. We've also included decoupling capacitors, and a red power
indicator LED; but beyond those we've tried to keep the board as simple
and straightforward as possible. If you want to start developing with
this chip, but don't want to deal with soldering it, this is the board
The 6 pins labeled ICSP
are used to program the board through the PDI interface using the common
6 pin ICSP cable found on most AVR programmers. Also, this board ships
with the example code shown below and the JTAGEN bit set to 1 (JTAG
disabled, PDI enabled).
Note: We have found that when using a Dragon device,
you must use the JTAG interface, you can not program/debug over PDI. If
you are using the JTAGICE3 you can use either JTAG or PDI however, you
will need to change the PDI clock to run at 1 MHz or slower.
