Microchip Technology DV164232

Overview

DV164232 from Microchip Technology is a Power Debugger development tool supporting AVR MCU and SAM MCU families via Atmel Studio IDE, featuring high-speed USB 2.0 connectivity, hardware breakpoints, CoreSight/SWO trace, and multi-protocol serial debug (SPI, UART, I²C, USART) with 4-channel logic probe capability.

For engineers reviewing the DV164232 datasheet, DV164232 pinout, DV164232 application, or DV164232 equivalent, key selection factors include its native CoreSight trace support, 4-channel logic capture, protocol-flexible debug interface, and target power measurement readiness for low-power embedded firmware validation.

Technical Context

The DV164232 implements a dual-role USB HID + Microchip-class interface to enable seamless integration with Atmel Studio, delivering real-time SWO trace streaming and synchronized logic capture across four digital channels. It supports hardware-assisted breakpoints and target-dependent memory inspection without requiring external Vpp or Vdd supply control.

Unlike legacy debug probes, DV164232 integrates dedicated logic analyzer functionality alongside debug transport-capturing SPI, UART, I²C, and USART traffic simultaneously with instruction-level trace, all powered solely via USB with sub-1 mA target current draw.

FAQ

Does DV164232 support MPLAB X IDE?

No. The DV164232 is exclusively validated for Atmel Studio IDE and does not support MPLAB X IDE. Its firmware, driver stack, and debug protocol stack are built for ARM Cortex-M targets used in AVR and SAM families-not dsPIC or PIC architectures. Using DV164232 with MPLAB X IDE will result in unrecognized device or connection failure.

What debug protocols does DV164232 support for SAM MCU targets?

DV164232 supports SWD (Serial Wire Debug) and CoreSight-based SWO (Serial Wire Output) for SAM MCU targets. It does not support JTAG or cJTAG. Trace data is delivered over SWO using Atmel Studio's built-in trace viewer, and no external trace buffer or FPGA-based capture is required.

Can DV164232 supply power to the target board?

No. DV164232 does not provide programmable Vdd or power delivery to the target. It draws less than 1 mA from the target for signaling and operates entirely from USB bus power. Target board must be independently powered during DV164232 use.

How many logic channels does DV164232 offer, and what protocols can they decode?

DV164232 provides exactly 4 digital logic capture channels. These channels support protocol decoding for SPI, UART, I²C, and USART signals-configured and triggered within Atmel Studio's Logic Analyzer view. No CAN, LIN, or custom protocol decoding is supported.

Is DV164232 compatible with SAM E70 or SAM S70 series MCUs?

Yes. DV164232 supports all SAM MCU families listed in official Microchip documentation-including SAM E70, SAM S70, SAM D, SAM L, and SAM G series-provided they implement ARM Cortex-M7/M4/M0+ cores with SWD and SWO interfaces enabled in hardware.
