Microchip Technology ATSTK600-SC12

Overview

ATSTK600-SC12 from Microchip Technology (formerly Atmel) is a full-featured development and debugging platform for the AT32UC3L016/32/64 family of 32-bit AVR UC microcontrollers. It supports in-circuit programming, real-time trace via Nexus Class 2+, hardware-assisted capacitive touch evaluation, and low-power mode validation - all with native aWire/JTAG interface, 48-pin TQFP/QFN/TLLGA target socket, and on-board voltage regulation for 1.62–3.6 V operation.

For engineers reviewing the ATSTK600-SC12 datasheet, ATSTK600-SC12 pinout, ATSTK600-SC12 application, or ATSTK600-SC12 equivalent, this kit enables rapid prototyping of ultra-low-power embedded systems featuring up to 64 KB Flash, 36 PWM channels, dual TWI/I²C, four USARTs, and QTouch® capacitive sensing - with direct support for SleepWalking, DFLL clock tuning, and secure library execution via FlashVault.

Technical Context

The ATSTK600-SC12 is a dedicated hardware evaluation platform designed exclusively for the AT32UC3L016/32/64 series - not a standalone IC or component. It integrates a socketed 48-pin TQFP/QFN/TLLGA target interface, configurable power supply (1.62–3.6 V), onboard debugger (Nexus Class 2+ compliant), and physical jumpers for peripheral signal routing including TWI, USART, SPI, ADC, and CAT module connections.

It provides direct access to all 36 GPIO pins, five high-drive I/Os, JTAG/aWire debug signals (TCK/TMS/TDO/TDI/RESET_N), oscillator inputs (XIN0/XOUT0, XIN32/XOUT32), and analog resources (VDDANA, ADVREFP, GNDANA). The board supports both single-pin aWire debugging (muxed with RESET_N) and full 4-pin JTAG, with trace capability via NanoTrace over JTAG or aWire.

FAQ

What is the primary function of the ATSTK600-SC12?

The ATSTK600-SC12 is a hardware evaluation and development kit - not a microcontroller - designed to host, program, debug, and validate the AT32UC3L016/32/64 series MCUs. It provides physical socketing, power regulation, Nexus Class 2+ trace, aWire/JTAG interfaces, and routed access to all key peripherals including CAT, PWMA, TC, ADC, and TWI. Engineers use the ATSTK600-SC12 to prototype firmware before moving to custom PCBs.

Does the ATSTK600-SC12 support the full feature set of the AT32UC3L064?

Yes - the ATSTK600-SC12 fully supports all documented capabilities of the AT32UC3L064, including 64 KB Flash execution, 36 PWM channels, dual TWI at 400 kbit/s, four USARTs with hardware handshaking, SleepWalking power management, FlashVault secure library execution, and QTouch® capacitive sensing with up to 17 sensors. All 36 GPIOs and five high-drive pins are accessible via headers or test points on the ATSTK600-SC12 board.

Can the ATSTK600-SC12 be used with other AVR32 UC devices beyond AT32UC3L016/32/64?

No - the ATSTK600-SC12 is specifically configured for the AT32UC3L016/32/64 family in 48-pin TQFP/QFN/TLLGA packages. It does not support other AVR32 UC variants such as AT32UC3A, AT32UC3B, or AT32UC3C due to differences in pinout, voltage domains, debug architecture, and peripheral mapping. The ATSTK600-SC12's socket, signal routing, and firmware loader are calibrated exclusively for the AT32UC3L series.

How does the ATSTK600-SC12 enable low-power validation?

The ATSTK600-SC12 supports accurate low-power measurement through its regulated 1.62–3.6 V supply with current-sense capability, direct access to SleepWalking-enabled peripherals (e.g., AST, EIC, Peripheral Event System), and hardware-level control of power modes via PM registers. It allows engineers to verify sub-µA sleep currents, validate 9 nA retention mode with backup registers active, and correlate power states with real-time trace data - all using the AT32UC3L064's native picoPower® features during ATSTK600-SC12 operation.

Is QTouch® capacitive touch evaluation possible directly on the ATSTK600-SC12?

Yes - the ATSTK600-SC12 provides dedicated routing for the Capacitive Touch (CAT) module: CSA[16:0], CSB[16:0], SYNC, VDIVEN, DIS, and SMP signals are exposed on labeled headers. Combined with Microchip's QTouch Studio and pre-certified QTouch Library, users can develop and tune capacitive buttons, sliders, and wheels on the ATSTK600-SC12 without external hardware - leveraging the AT32UC3L064's hardware-accelerated acquisition and Adjacent Key Suppression® (AKS®) built into the CAT module.
