Microchip Technology ATSTK600-RC95

Overview

ATSTK600-RC95 from Microchip Technology (formerly Atmel) is a development kit designed to evaluate the AT32UC3L064/032/016 family of 32-bit AVR UC microcontrollers. It supports full-speed debugging via JTAG and aWire, provides access to all 48-pin TQFP/QFN/TLLGA I/Os, and integrates hardware for capacitive touch evaluation, real-time clock validation, and low-power mode testing. The kit enables rapid prototyping of ultra-low-power embedded applications requiring up to 64KB Flash, 36 PWM channels, and dual TWI interfaces.

For engineers reviewing the ATSTK600-RC95 datasheet, ATSTK600-RC95 pinout, ATSTK600-RC95 application, or ATSTK600-RC95 equivalent, this board delivers validated hardware reference design, on-chip debug trace support (Nexus Class 2+), configurable power domains (1.62–3.6 V), and direct interface to AT32UC3L's Peripheral Event System - critical for evaluating SleepWalking, autonomous peripheral operation, and secure library execution using FlashVault technology.

Technical Context

The ATSTK600-RC95 is a dedicated evaluation platform for the AT32UC3L series, not a standalone IC. It routes all signals from the mounted AT32UC3L064 (64KB Flash, 16KB SRAM, 36 GPIO) to accessible headers and test points, including dedicated connectors for TWI, USART, SPI, ADC inputs, and capacitive touch sense lines (CSA/CSB). It implements the full picoPower® power management architecture with independent VDDCORE (1.62–1.98 V), VDDIO (1.62–3.6 V), and VDDANA (1.62–1.98 V) domains.

Hardware features include selectable crystal oscillators (32kHz and 3–16MHz), RC32OUT clock output on PA20, JTAG-to-aWire multiplexing control, and support for both single-pin aWire (via RESET_N) and standard 4-pin JTAG debugging. The board enables validation of Secure Access Unit (SAU)-enforced peripheral protection, MPU-configured memory regions, and non-intrusive NanoTrace program/data trace.

FAQ

What microcontroller is pre-mounted on the ATSTK600-RC95 evaluation board?

The ATSTK600-RC95 comes with the AT32UC3L064 microcontroller soldered onboard - a 32-bit AVR UC device featuring 64KB Flash, 16KB SRAM, 36 GPIO, and full picoPower® support. This specific variant enables evaluation of high-end peripherals including 36 PWM channels, dual TWI interfaces, and the Capacitive Touch (CAT) module. The ATSTK600-RC95 is configured to fully expose and validate all capabilities of the AT32UC3L064, not lower-density variants like AT32UC3L032 or AT32UC3L016.

Does the ATSTK600-RC95 support both JTAG and aWire debugging protocols?

Yes, the ATSTK600-RC95 supports both JTAG (4-pin interface) and aWire (single-pin interface multiplexed with RESET_N) for on-chip debugging and trace. It implements Nexus Class 2+ compliance and NanoTrace capability, enabling non-intrusive real-time program and data trace. The board includes hardware switches and jumpers to configure debug mode selection, ensuring compatibility with Microchip's Atmel Studio and third-party debuggers supporting either protocol. The ATSTK600-RC95 maintains full signal integrity for both interfaces without shared pin conflicts.

Can the ATSTK600-RC95 be used to evaluate low-power SleepWalking functionality?

Yes, the ATSTK600-RC95 provides direct hardware access to all power domains (VDDCORE, VDDIO, VDDANA), reset sources (POR, BOD, WDT), and clock sources (DFLL, OSC0, OSC32K, RCSYS) required to validate SleepWalking. It enables triggering peripheral wake-up events (e.g., TWI address match, USART RX activity, or CAT sensor activation) while the CPU remains in deep sleep. The board's routed EIC pins (EXTINT[5:1]), AST timer, and configurable power monitoring allow precise measurement of current draw during autonomous peripheral operation - a core use case for the AT32UC3L064's picoPower® architecture.

How does the ATSTK600-RC95 support capacitive touch development with the AT32UC3L064?

The ATSTK600-RC95 includes dedicated headers for all 17 CSA and 17 CSB lines, plus SMP, SYNC, VDIVEN, and DIS signals required by the AT32UC3L064's Capacitive Touch (CAT) module. It supports both QTouch® button/slider/wheel acquisition and QMatrix® matrix sensing. The board allows connection of external PCB-based touch sensors or evaluation kits and enables validation of hardware-assisted acquisition, adjacent key suppression (AKS®), and autonomous wakeup from sleep modes - all natively supported by the AT32UC3L064's CAT peripheral and QTouch Library integration.

Is FlashVault technology and Secure Access Unit (SAU) functionality testable on the ATSTK600-RC95?

Yes, the ATSTK600-RC95 enables full validation of FlashVault-secured libraries and SAU-configured peripheral protection. It provides access to the AT32UC3L064's secure boot configuration bits, MPU region registers, and SAU control registers via JTAG/aWire. Engineers can program encrypted secure libraries into Flash, configure SAU to restrict peripheral access (e.g., block UART access in non-secure state), and verify runtime enforcement - all using standard Atmel Studio tools. The ATSTK600-RC95's routed debug interface preserves all security-critical signals required for this validation.
