Microchip Technology ATSTK600-RC23

Overview

ATSTK600-RC23 from Microchip Technology (formerly Atmel) is a full-featured evaluation and development kit designed specifically for the AT32UC3L016/032/064 family of 32-bit AVR UC microcontrollers. It provides hardware abstraction, on-board debugging via JTAG/aWire, configurable power domains (1.62–3.6 V), and direct access to all 48-pin TQFP/QFN/TLLGA I/Os-including 36 GPIO, 5 high-drive pins, and dedicated capacitive touch, ADC, PWM, USART, SPI, TWI, and timer peripherals. It enables rapid prototyping of ultra-low-power embedded control applications such as smart sensors and battery-powered HMI.

For engineers reviewing the ATSTK600-RC23 datasheet, ATSTK600-RC23 pinout, ATSTK600-RC23 application, or ATSTK600-RC23 equivalent, this page delivers verified hardware interface details, supported target MCU variants (AT32UC3L016/032/064), debug protocol compatibility (JTAG Class 2+, aWire), power domain configuration options, and real-world use-case validation for low-power timing, capacitive touch, and peripheral event-driven design.

Technical Context

The ATSTK600-RC23 is not a semiconductor component but a purpose-built hardware platform that hosts and interfaces with the AT32UC3L series MCUs. It implements a modular architecture with detachable target boards, onboard EDBG debugger, configurable voltage regulators (VDDCORE, VDDIO, VDDANA), and jumper-selectable oscillator sources (32 kHz crystal, DFLL, RC oscillators).

It supports all key features of the AT32UC3L016/032/064 - including picoPower® operation down to 9 nA standby, SleepWalking™ peripheral wake-up, Peripheral Event System, 36-channel 8-bit PWM, 8-channel 12-bit ADC with internal temperature sensor, and QTouch® capacitive sensing - through direct signal routing, test points, and expansion headers aligned to the MCU's native pinout.

FAQ

What is the primary function of the ATSTK600-RC23?

The ATSTK600-RC23 is a complete evaluation and development platform for the AT32UC3L016/032/064 32-bit AVR UC microcontrollers. It provides hardware abstraction, on-board EDBG debugging, configurable power domains, and full pin access - enabling rapid firmware validation, low-power optimization, capacitive touch integration, and peripheral interface testing without custom PCB design. The ATSTK600-RC23 is not a standalone IC but a certified reference system for the AT32UC3L series.

Which microcontrollers does the ATSTK600-RC23 support?

The ATSTK600-RC23 is explicitly designed for the AT32UC3L016, AT32UC3L032, and AT32UC3L064 microcontrollers in 48-pin TQFP, QFN, and TLLGA packages. It supports all documented features of these devices - including picoPower® operation, SleepWalking™, Peripheral Event System, 36-channel PWM, 8-channel 12-bit ADC, and QTouch® capacitive sensing - via direct signal routing and matching pinout mapping.

Does the ATSTK600-RC23 support both JTAG and aWire debugging?

Yes, the ATSTK600-RC23 supports both JTAG (Nexus Class 2+) and single-pin aWire debugging protocols through its integrated EDBG interface. The aWire functionality uses the RESET_N pin as the data line, allowing full debug capability - including non-intrusive trace and runtime control - while freeing all standard JTAG pins (TCK, TMS, TDI, TDO) for GPIO or peripheral use during application execution. This dual-mode support is confirmed in the AT32UC3L datasheet and STK600 user guide.

Can the ATSTK600-RC23 be used for ultra-low-power design validation?

Yes, the ATSTK600-RC23 enables accurate ultra-low-power validation for the AT32UC3L series. It provides independent, jumper-selectable regulation for VDDCORE (1.62–1.98 V), VDDIO (1.62–3.6 V), and VDDANA (1.62–1.98 V), plus direct measurement points for current consumption in active, idle, and backup modes. Its support for SleepWalking™, RTC (AST + 32 kHz crystal), and 9 nA retention mode aligns precisely with the AT32UC3L's picoPower® specifications - allowing engineers to verify real-world power budgets before final hardware spin.

Is the ATSTK600-RC23 compatible with third-party IDEs and toolchains?

Yes, the ATSTK600-RC23 is fully compatible with Microchip Studio (formerly Atmel Studio), GCC-based toolchains (AVR32-GCC), and ARM-compatible debuggers supporting Nexus Class 2+ and aWire protocols. Its EDBG interface presents as a standard CMSIS-DAP-compliant device, enabling integration with SEGGER Embedded Studio, IAR Embedded Workbench, and Eclipse-based environments - provided the target AT32UC3L firmware image is built for the correct memory map and clock configuration used by the ATSTK600-RC23 hardware.
