Microchip Technology MA320002-2

Overview

MA320002-2 from Microchip Technology is a 100-pin USB Plug-In Module (PIM) designed to interface the PIC32MX470F512L 32-bit microcontroller with Explorer 16 and compatible development boards. It provides full pin mapping for USB 2.0 device functionality, 512 KB Flash, 128 KB RAM, and supports USB On-The-Go via VBUSON and USBID pins in a TQFP-100 footprint.

For engineers reviewing the MA320002-2 datasheet, MA320002-2 pinout, MA320002-2 application, or MA320002-2 equivalent, this module enables rapid evaluation of PIC32MX470F512L USB peripheral integration, real-time debugging via trace port, and high-speed communication in embedded control and connectivity prototyping.

Technical Context

The MA320002-2 implements a direct 100-pin-to-100-pin mechanical and electrical interface between the PIC32MX470F512L MCU and host development platforms. It routes all critical signals-including USB D+/D−, VBUS, USBID, VUSB3V3, and trace port pins (TRCLK, TRD0–TRD3)-with controlled impedance and decoupling per Microchip's reference design.

It integrates dedicated 10 µF and multiple 0.1 µF ceramic capacitors for VDD, AVDD, and VUSB3V3 stabilization, and includes configurable 22 Ω series resistors on trace lines (R1–R5) plus zero-ohm jumpers (R6–R10) for isolation-enabling both debug visibility and production-like signal integrity validation.

FAQ

What is the primary function of the MA320002-2?

The MA320002-2 is a USB Plug-In Module that mechanically and electrically interfaces the PIC32MX470F512L microcontroller to Explorer 16 and other compatible development boards. It provides validated routing for USB signals, power domains, and trace debugging-enabling immediate firmware testing without custom PCB design. The MA320002-2 serves as a production-representative hardware reference for USB peripheral validation.

Does the MA320002-2 support USB On-The-Go (OTG) functionality?

Yes, the MA320002-2 supports USB OTG through explicit routing of VBUSON and USBID pins from the PIC32MX470F512L to the PIM edge connector. These signals allow the MA320002-2 to detect host/device role negotiation and enable dual-role operation when used with appropriate firmware on the MA320002-2's target MCU.

How is the trace port implemented on the MA320002-2?

The MA320002-2 exposes the PIC32MX470F512L's 5-pin trace interface (TRCLK, TRD0–TRD3) via dedicated pads and includes 22 Ω series resistors (R1–R5) plus zero-ohm jumpers (R6–R10) for optional isolation. This allows engineers to monitor real-time instruction execution on the MA320002-2 during debug sessions while maintaining signal integrity.

What power supply configurations does the MA320002-2 support?

The MA320002-2 supports separate VDD (digital core), AVDD (analog), and VUSB3V3 (USB PHY) rails, each with dedicated decoupling: one 10 µF bulk capacitor and multiple 0.1 µF ceramics. This ensures low-noise operation for mixed-signal and USB timing-critical functions on the MA320002-2.

Is the MA320002-2 compatible with development tools beyond Explorer 16?

Yes-the MA320002-2 adheres to the standard 100-pin PIM mechanical and pinout specification defined in Microchip document DS50002162B. It is compatible with any host board supporting the same 100-pin PIM socket interface, including third-party development platforms certified for PIC32MX470F512L evaluation.
