Atmel AT32UC3B1256, AVR32 microcontroller module with USB interface



B1DIL is a tiny interface module for an Atmel AVR32 micro controller with USB interface in TQFP48 casing. The module fits to an ordinary 40 pin dual-in-line socket. The module is helpful in experiments, development and prototyping with USB-AVR32 microcontrollers.
  • assembled with Atmel AVR microcontroller AT32UC3B1256
  • standard 40 pin dual-inline format (0.6 inch row distance)
  • any microcontroller port (except USB data) is available by the dual in line pins
  • flexibel power supplement by USB or external, 3.3V regulator on board
  • oscillator socket onboard (suitable for crystal, 2- and 3-pin ceramic resonator)
  • all components for basic operation onboard (such as resistors and buffer capacitors)
  • ESD protected Mini-USB connector
  • JTAG connector for in-system programming and debugging (10 pin Atmel JTAG standard)
  • directly supported by AVR Studio 5

The module can be applied in any development system, such as Atmel AVR Studio and IAR Embedded Workbench® for Atmel AVR.

For In-System-Programming and debugging the Atmel AVRJTAG MKII or JTAGICE 3 and all the compatible devices can be used.

The microcontroller can be programmed in two ways:

  • By the USB interface with the present bootloader and the command line tool "batchisp" from Atmel (contained in the installation package of "FLIP").
  • Programming and debugging by JTAG interface and a suitable debugging device such as Atmel AVRJTAG MKII (or compatible such as Kee AVR JTAG MKII from Kee Electronics).
