Microchip Technology ATSTK600-RC46

Overview

ATSTK600-RC46 from Microchip Technology (formerly Atmel) is a development kit designed to evaluate the AT32UC3L064, AT32UC3L032, and AT32UC3L016 32-bit AVR UC microcontrollers. It supports full debugging via JTAG and aWire interfaces, provides access to all 48 pins of the TQFP/QFN/TLLGA package, and enables rapid prototyping of low-power embedded applications including capacitive touch, real-time clock, and multi-channel PWM control.

For engineers reviewing the ATSTK600-RC46 datasheet, ATSTK600-RC46 pinout, ATSTK600-RC46 application, or ATSTK600-RC46 equivalent, this kit delivers validated hardware reference design, on-chip debug trace (Nexus Class 2+), SleepWalking power management verification, QTouch library integration support, and direct peripheral-to-peripheral event system testing - critical for ultra-low-power MCU selection and firmware validation.

Technical Context

The ATSTK600-RC46 is a dedicated evaluation platform for the AT32UC3L family, featuring socketed 48-pin TQFP/QFN/TLLGA target socket, onboard debugger (JTAG/aWire), and routed signal access to all GPIO, analog, and communication peripherals. It supports full-speed non-intrusive trace via NanoTrace and runtime control through the integrated Nexus 2.0 OCD interface.

Hardware-level features include configurable power domains (VDDCORE, VDDIO, VDDANA), RC32K oscillator startup clock output on PA20, TWI/SPI/USART signal routing with level-shifting, and dedicated headers for CAT module capacitive sense lines (CSA/CSB), ADC inputs, and PWM outputs - enabling accurate validation of picoPower® operation, peripheral DMA transfers, and secure MPU/SAU memory protection behavior.

FAQ

What is the primary function of the ATSTK600-RC46?

The ATSTK600-RC46 is a hardware evaluation kit for the AT32UC3L064/032/016 microcontrollers. It provides physical access to all 48 pins, integrated JTAG/aWire debugging, power domain isolation, and routed signals for peripherals including CAT, ADC, PWM, and real-time clock - enabling complete functional and low-power validation of the target MCU before custom PCB design.

Does the ATSTK600-RC46 support the full picoPower® feature set of the AT32UC3L devices?

Yes, the ATSTK600-RC46 enables verification of all picoPower® capabilities including SleepWalking, autonomous wake-up from AST/AC/CAT/EIC sources, backup register retention at 9 nA, and dynamic voltage/frequency scaling. Test points and jumper-configurable power domains allow precise current measurement across active, idle, and backup modes for the AT32UC3L device mounted on the board.

Can the ATSTK600-RC46 be used to develop capacitive touch applications with QTouch Library?

Yes - the ATSTK600-RC46 provides direct header access to all 17 CSA/CSB lines, SMP, SYNC, VDIVEN, and DIS signals required by the CAT module. It supports both self-capacitance and mutual-capacitance configurations and is fully compatible with Atmel QTouch Studio and the production-ready QTouch Library for buttons, sliders, and wheels - verified with AT32UC3L064/032/016 MCUs.

Is NanoTrace trace functionality available on the ATSTK600-RC46?

Yes, the ATSTK600-RC46 supports NanoTrace through both JTAG and aWire interfaces. When connected to a compatible debugger (e.g., Atmel-ICE), it delivers non-intrusive program and data trace, instruction execution logging, and real-time variable monitoring - essential for optimizing code size, verifying interrupt latency, and validating MPU/SAU memory protection behavior on the AT32UC3L device.

Does the ATSTK600-RC46 support all oscillator configurations listed in the AT32UC3L datasheet?

Yes - the ATSTK600-RC46 provides solderable pads and jumpers for OSC0 (XIN0/XOUT0), primary and secondary 32 kHz crystals (XIN32/XOUT32 and XIN32_2/XOUT32_2), DFLL reference input, and RC oscillator outputs (RC32OUT on PA20). This allows full validation of all clock sources - including DFLL tuning, AST calendar mode, and failover between oscillators - as specified for the AT32UC3L064/032/016.
