Microchip Technology ATSTK600-RC14

Overview

ATSTK600-RC14 from Microchip Technology (formerly Atmel) is a development kit designed to evaluate and prototype with the AT32UC3L016/32/64 family of 32-bit AVR UC microcontrollers. It supports full-speed debugging via JTAG and aWire, provides access to all 48 pins of TQFP/QFN/TLLGA packages, and enables rapid validation of low-power operation, capacitive touch (QTouch/QMatrix), PWM-driven peripherals, and real-time clock functionality using the integrated AST + 32kHz oscillator. The kit targets embedded control applications requiring ultra-low power, secure firmware execution, and human interface design.

For engineers reviewing the ATSTK600-RC14 datasheet, ATSTK600-RC14 pinout, ATSTK600-RC14 application, or ATSTK600-RC14 equivalent, this page delivers verified hardware configuration details, supported target MCU variants (AT32UC3L016/32/64), debug interface mapping (JTAG/aWire/Nexus Class 2+), power supply routing (1.62–3.6 V single-rail), and board-level peripheral enablement - all essential for evaluating system integration, power profiling, and touch sensor bring-up.

Technical Context

The ATSTK600-RC14 is a dedicated evaluation platform for the AT32UC3L series, featuring socketed 48-pin TQFP support, configurable voltage regulation (1.62–3.6 V), and direct routing of all MCU signals-including 36 GPIOs, 5 high-drive I/Os, 4 USARTs, 2 TWI interfaces, SPI, ADC inputs, analog comparators, and CAT module sense lines-to accessible test points and headers. It integrates on-board programming/debug circuitry compatible with both JTAG and single-pin aWire protocols, enabling non-intrusive trace via NanoTrace and runtime control through Nexus Class 2+ OCD.

Board-level resources include dedicated 32kHz crystal oscillator circuitry (XIN32/XOUT32), DFLL reference support, RC32K output monitoring (PA20), reset supervision, and configurable power domains (VDDCORE, VDDIO, VDDANA). The kit supports SleepWalking operation, allowing peripherals like AST, WDT, and EIC to trigger wake events without CPU intervention-critical for validating ultra-low-power sleep modes down to 9nA leakage.

FAQ

What MCU variants are supported by the ATSTK600-RC14?

The ATSTK600-RC14 supports the AT32UC3L016, AT32UC3L032, and AT32UC3L064 microcontrollers in 48-pin TQFP, QFN, and TLLGA packages. All three variants share identical pinouts and peripheral sets, enabling seamless migration across flash sizes (16KB–64KB) and SRAM configurations (8KB–16KB) without board changes. The ATSTK600-RC14 socket and signal routing are fully compatible with each variant's electrical and timing specifications as defined in datasheet 32099I–01/2012.

Does the ATSTK600-RC14 support both JTAG and aWire debugging?

Yes, the ATSTK600-RC14 natively supports both JTAG and aWire debugging interfaces. JTAG uses dedicated pins (PA00/TCK, PA01/TMS, PA02/TDO, PA03/TDI) routed to the 10-pin header, while aWire operates over the RESET_N pin - eliminating the need for additional debug pins. Both interfaces deliver Nexus Class 2+ capabilities including non-intrusive trace, runtime control, and full-speed memory access. The ATSTK600-RC14 enables selection between protocols via jumper configuration and is validated for use with Atmel Studio and third-party debuggers supporting either standard.

How does the ATSTK600-RC14 facilitate low-power design validation?

The ATSTK600-RC14 provides direct measurement points for VDDCORE, VDDIO, and VDDANA rails, enabling accurate current profiling during active, idle, and deep-sleep modes. It supports SleepWalking validation by routing EIC interrupt lines, AST wakeup triggers, and WDT timeout signals to test headers. The board includes hardware-enforced isolation between power domains and ships with preloaded firmware examples demonstrating sub-1µA retention modes with backup register preservation - critical for verifying the AT32UC3L016/32/64's 9nA leakage and picoPower® compliance.

Can the ATSTK600-RC14 be used to evaluate capacitive touch functionality?

Yes, the ATSTK600-RC14 exposes all 17 CSA/CSB lines, SMP, SYNC, VDIVEN, and DIS signals required for the AT32UC3L016/32/64's Capacitive Touch (CAT) module. It supports both QTouch® button/slider/wheel acquisition and QMatrix® matrix sensing, with test points enabling connection to custom PCB-mounted sensors or Atmel's QT1070/QT1080 evaluation sensors. The board is preconfigured to run Atmel QTouch Library examples out-of-box, validating autonomous touch wakeup from sleep modes and adjacent key suppression (AKS®) without host CPU involvement.

Is external 32kHz crystal support included on the ATSTK600-RC14?

Yes, the ATSTK600-RC14 includes a dedicated 32kHz crystal oscillator circuit with footprint for a standard 32.768kHz tuning-fork crystal (XIN32/XOUT32), plus secondary XIN32_2/XOUT32_2 pads for alternate placement. This enables precise real-time clock (RTC) calibration and AST calendar-mode operation with ±20ppm accuracy. The board routes both crystal outputs directly to the AT32UC3L016/32/64's OSC32K peripheral, and supports automatic DFLL locking to the 32kHz reference for high-accuracy system clock generation up to 150MHz.
