Microchip Technology ATSTK600-RC90

Overview

ATSTK600-RC90 from Microchip Technology (formerly Atmel) is a development and evaluation kit designed for the AT32UC3L016/032/064 family of 32-bit AVR UC microcontrollers. It provides full hardware access to all I/O, peripherals, and debug interfaces-including JTAG, aWire, and Nexus Class 2+ trace-enabling firmware validation, capacitive touch tuning, low-power mode testing, and real-time debugging of applications leveraging PWM, USART, TWI, ADC, and CAT modules. The kit supports TQFP48/QFN48/TLLGA48 packages and integrates on-board programming, voltage regulation, and configurable signal routing.

For engineers reviewing the ATSTK600-RC90 datasheet, ATSTK600-RC90 pinout, ATSTK600-RC90 application, or ATSTK600-RC90 equivalent, this page delivers verified technical context, key specifications, supply availability, manufacturer background, and targeted FAQs-all grounded in official Microchip documentation for the AT32UC3L series and STK600 platform.

Technical Context

The ATSTK600-RC90 is a hardware evaluation platform-not an IC-and serves as the reference interface between host PC tools (Atmel Studio, QTouch Suite) and target AT32UC3L016/032/064 MCUs. It implements full JTAG/aWire/Nexus trace connectivity, programmable voltage rails (1.62–3.6 V), and jumper-configurable peripheral routing to match TQFP48/QFN48/TLLGA48 pinouts.

It enables direct validation of picoPower® low-power features (e.g., SleepWalking, AST calendar mode, 9 nA standby), secure boot via FlashVault, and capacitive touch acquisition using QTouch® and QMatrix® libraries-leveraging the CAT module's 17-sensor support and autonomous wakeup capability.

FAQ

What is the primary function of the ATSTK600-RC90?

The ATSTK600-RC90 is a universal development board specifically configured for the AT32UC3L016/032/064 32-bit AVR UC microcontrollers. Its primary function is to provide full hardware access-including JTAG, aWire, and Nexus trace-for firmware development, low-power mode validation, capacitive touch tuning with QTouch libraries, and peripheral interface testing. It is not a standalone IC but a certified evaluation platform supporting TQFP48/QFN48/TLLGA48 packages.

Does the ATSTK600-RC90 support the AT32UC3L064's 50 MHz operation and picoPower® features?

Yes, the ATSTK600-RC90 fully supports the AT32UC3L064's maximum 50 MHz operation and all picoPower® features-including SleepWalking, AST calendar mode, 9 nA standby with backup registers retained, and dynamic clock gating. The board provides stable power regulation, configurable oscillator inputs (XIN0/XOUT0, XIN32/XOUT32), and precise timing signal routing required to validate these low-power behaviors in real-world conditions.

Can the ATSTK600-RC90 be used to develop capacitive touch applications with the CAT module?

Yes, the ATSTK600-RC90 provides complete hardware access to the CAT module signals-CSA[16:0], CSB[16:0], SMP, SYNC, VDIVEN, and DIS-enabling direct connection and tuning of up to 17 discrete or 16×8 matrix capacitive sensors. It is validated for use with Atmel QTouch Library and QTouch Suite, supporting autonomous wakeup, adjacent key suppression (AKS®), and robust charge-transfer acquisition without external components.

What debug capabilities does the ATSTK600-RC90 offer for the AT32UC3L series?

The ATSTK600-RC90 supports full Nexus Class 2+ On-chip Debug (OCD) with non-intrusive real-time trace, runtime control, and full-speed memory access. It routes MDO[5:0], MSEO[1:0], EVTI_N, and EVTO_N pins for trace capture, and provides both standard 4-pin JTAG and single-pin aWire (muxed with RESET_N) for programming and debugging-ensuring compatibility with Atmel Studio, third-party JTAG probes, and NanoTrace-enabled tools.

Is the ATSTK600-RC90 compatible with other AVR UC devices beyond the AT32UC3L family?

No-the ATSTK600-RC90 is specifically configured for the AT32UC3L016/032/064 family. While the broader STK600 platform supports multiple AVR UC and megaAVR devices via interchangeable routing boards and adapters, the RC90 variant includes fixed signal routing, voltage settings, and oscillator configurations optimized exclusively for the AT32UC3L series' pinout, power domains (VDDCORE/VDDANA), and peripheral feature set (e.g., CAT, PWMA, AST).
