Product details
Overview
AC320202 from Microchip Technology is an isolated EDBG (Embedded Debugger) daughter card designed to program and debug SAM/PIC32C microcontroller-based Plug-in Modules (PIMs) on high-voltage development boards including dsPICDEM MCHV-2 (DM330023-2) and dsPICDEM MCHV-3 (DM330023-3). It provides galvanic isolation between host PC and target motor control system, supports both high-speed and full-speed USB interfaces, and integrates SWD/JTAG debug circuitry with status LEDs and voltage detection.
For engineers reviewing the AC320202 datasheet, AC320202 pinout, AC320202 application, or AC320202 equivalent, this page delivers verified technical context, isolation specifications, USB interface compatibility, target reset sensing capability, and integration requirements for high-voltage motor control evaluation platforms.
Technical Context
The AC320202 implements bidirectional galvanic isolation using Silicon Labs SI8605AC-B-IS1 digital isolators for SWD signals (SWDIO/SWCLK), reset, and power domains. It interfaces with host PCs via mini-USB (USB 2.0 compliant) and connects to target PIMs through 6-pin and 4-pin 1.27 mm pitch headers supporting ICSP, SWD, and UART functions.
It features dual USB signaling paths-EDBG_USB_HS_P/N for high-speed debugging and EDBG_USB_FS_P/N for full-speed fallback-with integrated VBUS sensing, 12 MHz crystal oscillator (CX2520DB12000H0FLJC1), and isolated 3.3 V power domain (VDD_ISO) derived from target board's VDD_ISO_MCHV rail.

FAQ
What is the primary function of the AC320202?
The AC320202 is an isolated EDBG daughter card that enables safe programming and debugging of SAM/PIC32C microcontroller-based Plug-in Modules mounted on high-voltage development boards such as dsPICDEM MCHV-2 and MCHV-3. It provides galvanic isolation between the host PC and target system, preventing ground loop issues and protecting equipment during 90–230 VAC operation. The AC320202 uses SWD/JTAG protocols and integrates USB connectivity, status LEDs, and voltage sensing to support robust firmware development workflows.
Which development boards is the AC320202 compatible with?
The AC320202 is explicitly designed for use with Microchip's dsPICDEM MCHV-2 (DM330023-2) and dsPICDEM MCHV-3 (DM330023-3) high-voltage development boards. It replaces the original Pickit On Board (PKOB) debugger card and requires compatible SAM/PIC32C Motor Control PIMs and matching OPAMP matrix boards. The AC320202 connects via standardized 1.27 mm and 2.54 mm pitch headers and relies on the board's VDD_ISO_MCHV rail for isolated power.
Does the AC320202 support both SWD and JTAG interfaces?
Yes, the AC320202 supports both Serial Wire Debug (SWD) and JTAG interfaces through dedicated signal routing: SWDIO, SWDCLK, TMS, TDO, TDI, and TCK are all isolated and routed to target PIMs via header pins. The onboard AT32UC3A4256J-C1UR microcontroller handles protocol translation and USB bridging. This dual-protocol capability ensures compatibility with MPLAB X and Atmel Studio IDEs when debugging SAM/PIC32C devices using the AC320202.
What isolation components are used in the AC320202?
The AC320202 employs Silicon Labs SI8605AC-B-IS1 quad-channel digital isolators to provide galvanic isolation for SWD signals (SWDIO/SWCLK), reset (nRESET), and power domains. These isolators meet reinforced insulation requirements and support data rates up to 150 Mbps. Isolation extends across debug signaling, target reset sensing, and power monitoring paths - critical for safe operation when interfacing with mains-referenced motor control circuits. The AC320202 does not rely on optocouplers or transformer-based isolation.
Can the AC320202 be used with non-Microchip IDEs or toolchains?
The AC320202 is natively supported by Microchip's MPLAB X IDE and legacy Atmel Studio, which recognize it as an EDBG-compliant debugger. While third-party tools may access it via CMSIS-DAP or generic USB CDC interfaces, official driver support, firmware updates, and debug feature parity (e.g., trace, SWO, chip erase) are only guaranteed within Microchip's validated toolchain. Use outside those environments requires manual USB descriptor handling and is not covered by Microchip's documentation for the AC320202.
