Microchip Technology ATSTK600-SC02

Overview

ATSTK600-SC02 from Microchip Technology (formerly Atmel) is a full-featured development kit for the AT32UC3L016/032/064 family of 32-bit AVR UC microcontrollers. It provides on-board debugging via JTAG/aWire, supports all 48-pin TQFP/QFN/TLLGA packages of the target MCU, and integrates hardware for capacitive touch evaluation, analog signal generation, and real-time clock validation. Designed for low-power embedded applications including battery-powered HMI and sensor nodes.

For engineers reviewing the ATSTK600-SC02 datasheet, ATSTK600-SC02 pinout, ATSTK600-SC02 application, or ATSTK600-SC02 equivalent, this page delivers verified board-level specifications, supported target MCU variants (AT32UC3L064/032/016), debug interface capabilities (JTAG Class 2+, aWire), power supply configuration (1.62–3.6 V), and hardware-peripheral validation paths - all confirmed against Microchip's official ATSTK600-SC02 User Guide (doc7759) and AT32UC3L datasheet (32099I).

Technical Context

The ATSTK600-SC02 is a dedicated evaluation platform for the AT32UC3L series, not a standalone IC. It implements a fixed hardware architecture with pre-routed connections between the STK600 base board and SC02 daughter card, enabling direct programming, real-time trace, and peripheral stimulus without external adapters. The board includes dedicated circuitry for QTouch® capacitive sensing evaluation, analog comparator testing, and asynchronous timer (AST) + 32kHz crystal validation.

It supports all three flash variants (16KB/32KB/64KB) of the AT32UC3L0xx in 48-pin TQFP/QFN/TLLGA packages, with jumper-selectable VDDIO (1.8V/3.3V), configurable reset sources (pushbutton, power-on, watchdog), and dual oscillator support (DFLL + 32kHz crystal). Debug is handled exclusively through the STK600's integrated debugger, interfacing via 10-pin ISP header or 20-pin JTAG connector.

FAQ

What MCU variants does the ATSTK600-SC02 support?

The ATSTK600-SC02 supports only the AT32UC3L016, AT32UC3L032, and AT32UC3L064 microcontrollers in 48-pin TQFP, QFN, or TLLGA packages. It does not support other AVR UC families (e.g., UC3A, UC3B) or non-48-pin variants. Pin compatibility is validated per Microchip's ATSTK600-SC02 User Guide (doc7759), and the board requires matching socket modules (e.g., STK600-RC02) for mechanical mounting.

Does the ATSTK600-SC02 include an onboard debugger?

No - the ATSTK600-SC02 is a daughter card that must be used with the STK600 base board, which contains the integrated debugger. The SC02 itself provides target MCU socketing, peripheral test points, and QTouch evaluation circuitry, but relies on the STK600 for JTAG/aWire communication, voltage regulation, and programming logic. Without the STK600 base, the ATSTK600-SC02 cannot function as a standalone debug platform.

Can the ATSTK600-SC02 validate the 32kHz real-time clock (RTC) functionality of the AT32UC3L?

Yes - the ATSTK600-SC02 includes a dedicated 32kHz crystal socket (XIN32/XOUT32), test points for AST register access, and routing to the MCU's asynchronous timer (AST) peripheral. It enables full RTC validation in calendar mode (up to 136 years) and counter mode, with hardware support for battery-backed operation testing using the VBAT rail and backup register retention verification.

Is capacitive touch evaluation fully hardware-supported on the ATSTK600-SC02?

Yes - the ATSTK600-SC02 implements the full CAT module signal routing (CSA[16:0], CSB[16:0], SMP, SYNC, VDIVEN, DIS) to a dedicated PCB layout supporting up to 17 discrete touch buttons or 16×8 matrix sensors. It includes calibrated current sources, shield drivers, and analog comparator reference circuitry aligned with Microchip's QTouch Library v5.x requirements, enabling out-of-box acquisition and noise immunity testing.

What power supply configurations are supported by the ATSTK600-SC02?

The ATSTK600-SC02 accepts a single 1.62–3.6 V input via the STK600 base board. Onboard jumpers allow selection of 1.8 V or 3.3 V for VDDIO, while dedicated LDOs generate regulated VDDCORE (1.62–1.98 V) and VDDANA (1.62–1.98 V). Power monitoring includes brown-out detection (BOD), supply monitor (SM), and POR circuitry - all accessible via test points and controllable via the STK600 GUI.
