Microchip Technology ATSTK600-RC05

Overview

ATSTK600-RC05 from Microchip Technology (formerly Atmel) is a production-ready evaluation and development kit for the AT32UC3L016/032/064 family of 32-bit AVR UC microcontrollers. It supports full-speed debugging, flash programming, and hardware validation of low-power embedded applications using the picoPower®-enabled AT32UC3L series. The kit integrates on-board debug interface, configurable power domains, and direct access to all 48-pin TQFP/QFN/TLLGA signals - enabling rapid prototyping of capacitive touch, real-time clock, PWM motor control, and multi-interface communication designs.

For engineers reviewing the ATSTK600-RC05 datasheet, ATSTK600-RC05 pinout, ATSTK600-RC05 application, or ATSTK600-RC05 equivalent, this kit delivers verified hardware reference for evaluating the AT32UC3L064's 50MHz RISC core, 36-channel PWM controller, 4x USARTs with SPI mode, 12-bit ADC, and QTouch® capacitive sensing capabilities under real-world voltage (1.62–3.6V), temperature, and low-power sleepwalking conditions.

Technical Context

The ATSTK600-RC05 is a dedicated hardware platform designed exclusively for the AT32UC3L016/032/064 microcontroller family. It implements the full AT32UC3L064 pinout across its expansion headers, including all 36 GPIOs, five high-drive I/O pins (PA02, PA06, PA08, PA09, PB01), JTAG/aWire debug interface (TCK/TMS/TDO/TDI on PA00–PA03), and dedicated analog supply rails (VDDANA, ADVREFP, GNDANA).

It provides direct access to all key peripherals: six 16-bit Timer/Counter channels, 36 PWM outputs (PWMA[35:0]), eight analog comparators, asynchronous timer with RTC calendar mode, frequency meter (FREQM), and the Capacitive Touch (CAT) module supporting up to 17 sensors or 16×8 matrix configurations - all validated against the AT32UC3L064's internal FlashVault™ secure library execution and MPU/SAU memory protection architecture.

FAQ

What is the primary function of the ATSTK600-RC05?

The ATSTK600-RC05 is a fully assembled, production-grade evaluation kit for the AT32UC3L016/032/064 microcontroller family. It enables hardware validation, firmware development, and performance benchmarking - including picoPower® low-power modes, SleepWalking peripheral activation, secure FlashVault™ library execution, and QTouch® capacitive sensing - without requiring custom PCB design. The ATSTK600-RC05 provides direct access to all 48 pins and integrated debug infrastructure for the AT32UC3L064 device.

Does the ATSTK600-RC05 support the full AT32UC3L064 feature set?

Yes, the ATSTK600-RC05 supports the complete AT32UC3L064 feature set: 50MHz operation, 36 PWM channels (PWMA[35:0]), 6x 16-bit Timer/Counter units, 4x USARTs with SPI/LIN modes, 2x TWI interfaces, 8-channel 12-bit ADC with internal temperature sensor, 8 analog comparators with window detection, and the Capacitive Touch (CAT) module with CSA/CSB/SMP/VDIVEN signal routing. All peripherals are electrically accessible via standardized headers aligned to the AT32UC3L064's TQFP48 pinout.

Can the ATSTK600-RC05 be used with other AT32UC3L variants?

Yes, the ATSTK600-RC05 is compatible with the entire AT32UC3L016/032/064 family. The board accepts any member of this family in 48-pin TQFP, QFN, or TLLGA packages. Differences in Flash (16KB/32KB/64KB) and SRAM (8KB/16KB) size are handled automatically by the on-board programming/debug interface. Firmware built for AT32UC3L064 will run on AT32UC3L032 or AT32UC3L016 if memory usage remains within their respective limits.

How does the ATSTK600-RC05 handle power domain configuration for low-power testing?

The ATSTK600-RC05 provides independent, jumper-selectable regulation for VDDCORE (1.62–1.98V), VDDIO/VDDIN (1.62–3.6V), and VDDANA (1.62–1.98V), allowing precise replication of the AT32UC3L064's multi-rail power architecture. Current measurement test points enable direct validation of active-mode consumption (down to 165µA/MHz) and deep-sleep leakage (as low as 9nA with backup registers retained), critical for verifying SleepWalking and picoPower® behavior defined in the AT32UC3L064 datasheet.

Is the ATSTK600-RC05 compatible with modern IDEs and debug tools?

Yes, the ATSTK600-RC05 is natively supported by Microchip Studio (formerly Atmel Studio), IAR Embedded Workbench for AVR32, and GCC-based toolchains via the included JTAGICE3-compatible debug interface. Its Nexus Class 2+ compliant on-chip debug system enables non-intrusive runtime trace, full-speed memory read/write, and NanoTrace over JTAG or aWire - ensuring full visibility into AT32UC3L064 execution flow, peripheral event timing, and secure state transitions during development.
