Introduction
Congratulations on your purchase of the AT43DK325 USB Development Kit. The
AT43DK325 is a complete starter kit and development system for Atmel’s
AT43USB325x family of AVR
®
based USB microcontrollers (MCUs). It provides all of
the necessary hardware and firmware components to facilitate rapid prototyping and
firmware development of the AT43USB325x applications.
1.1

The AT43DK325 Development Kit consists of the following:
n
Development Board for the AT43USB325/6 USB MCUs featuring
– An AT43USB325 full-speed USB controller programmable as a compound
device, a hub only device or a function only device
– One internal and four external downstream HUB ports
– 512 bytes on-chip program SRAM
– 16 Kbytes program memory
– Parallel interface to PC for In-System firmware programming
– Pin header connectors for access to all available GPIO pins
n

1.2
Device Support
The AT43DK325 Development Kit and the accompanying software tools are intended to
support firmware development and prototyping for the AT43USB325/6 family of USB
keyboard function controllers, including the
– AT43USB325E/M
– AT43USB326
Binary compatibility across the AT43USB325/6 family ensures that only one set of
development tools (development kit, compilers, etc.) is needed for all of the
AT43USB3xx based applications. Firmware written for one member of the family can be
