Microchip Technology DM320005-2

Overview

DM320005-2 from Microchip Technology is a Multimedia Expansion Board II (MEB II) - a fully integrated, detachable daughter-board-compatible development platform designed to extend PIC32-based starter kits with rich multimedia peripherals including VGA camera, 24-bit audio, Wi-Fi (802.11b/g), Bluetooth HCI, PCAP touch display interface, microSD, and sensor subsystems.

For engineers reviewing the DM320005-2 datasheet, DM320005-2 pinout, DM320005-2 application, or DM320005-2 equivalent, this board serves as a validated hardware reference for rapid prototyping of embedded multimedia applications targeting industrial HMI, portable audio/video devices, and connected IoT edge nodes with real-time sensor fusion and wireless connectivity.

Technical Context

The DM320005-2 functions as a peripheral expansion mother board that interfaces exclusively via a 168-pin Hirose FX10 board-to-board connector to compatible PIC32 starter kits (e.g., DM320003, DM320004), routing EBI signals for external SRAM, parallel RGB/TFT display timing (HSYNC/VSYNC/DE/PCLK), I²C buses for touch controller (MTCH6301) and audio codec (AK4953A), SPI for Wi-Fi (MRF24WG0MA), and dedicated GPIO for mTouch™ buttons, accelerometers (ADXL325), and temperature sensing (MCP9700T).

It integrates discrete subsystems including an OVM7690 VGA image sensor with 8-bit parallel output, AK4953A stereo audio codec supporting I²S data and I²C control, MRF24WG0MA 802.11b/g transceiver, BTM805 Bluetooth HCI module, and IS61WV102416BLL 2 MB synchronous SRAM - all electrically isolated and power-managed via on-board 5 V / 3.3 V regulators fed from a 9–15 V DC input.

FAQ

What is the DM320005-2 used for?

The DM320005-2 is a Multimedia Expansion Board II (MEB II) - a hardware development platform that adds VGA imaging, 24-bit audio, Wi-Fi, Bluetooth, PCAP touch, microSD, and sensor capabilities to PIC32 starter kits. It is not a standalone IC or module but a complete, tested PCB assembly intended for rapid prototyping and firmware validation of multimedia-enabled embedded systems. The DM320005-2 enables engineers to evaluate real-world integration of these features without custom hardware design.

Does the DM320005-2 include a microcontroller?

No, the DM320005-2 does not include a microcontroller. It is a peripheral expansion board that must be paired with a compatible PIC32 starter kit (e.g., DM320003 or DM320004) via its 168-pin Hirose FX10 connector. All processing, memory, and debug functionality reside on the starter kit; the DM320005-2 provides only peripheral interfaces, sensors, wireless modules, and display connectivity.

Which display interfaces does the DM320005-2 support?

The DM320005-2 supports parallel RGB/TFT displays through a 60-pin Hirose DF12 connector, delivering HSYNC, VSYNC, DE, PCLK, and 24-bit RGB data (R0–R7, G0–G7, B0–B7). It ships with a 4.3" WQVGA (480×272) PCAP touch display daughter board featuring the MTCH6301 touch controller. The interface is designed for detachable display boards, enabling resolution and technology flexibility beyond the included panel.

Can the DM320005-2 operate independently without a PIC32 starter kit?

No, the DM320005-2 cannot operate independently. It has no onboard MCU, clock source, or programming/debug circuitry. Power, processing, and core system control are provided exclusively by a connected PIC32 starter kit. All peripherals - including the OVM7690 camera, AK4953A audio codec, MRF24WG0MA Wi-Fi module, and MTCH6301 touch controller - rely on the PIC32 MCU for initialization, configuration, and data handling via routed I²C, SPI, EBI, and GPIO signals.

What wireless modules are integrated on the DM320005-2?

The DM320005-2 integrates two certified wireless modules: the MRF24WG0MA for IEEE 802.11b/g Wi-Fi communication and the BTM805 for Bluetooth Host Controller Interface (HCI) operation. Both modules connect to the PIC32 starter kit via dedicated SPI (Wi-Fi) and UART (Bluetooth) signal routing on the 168-pin interface. Antenna matching networks and regulatory-compliant RF layout are implemented on the DM320005-2 PCB.
