PIC32MM0256GPM028-I/M6 Übersicht
A 32-bit microcontroller (MCU) is a programmable system-on-chip that integrates a CPU core, program and data memory, and a configurable set of peripherals (timers, ADC, communication interfaces, GPIO). The PIC32MM GPM belongs to the hierarchy MCU -> 32-bit MCU -> MIPS-based MCU -> PIC32 family -> PIC32MM GPM sub-family, optimized for USB-connected, low-power embedded designs where deterministic code execution and small package size are required.
Key features include 256 KB ECC Flash for improved code reliability, 32 KB SRAM, USB 2.0 full-speed device/host/OTG support, multiple 16-bit and 32-bit timers, a 12-bit ADC, configurable logic cells (CLC), and a peripheral pin select (PPS) system that allows flexible signal routing. The 28-pin UQFN (4x4 mm) package with an exposed pad (EP) provides a compact footprint and a low thermal resistance path for the modest power dissipation of an MCU running at 25 MHz.
The PIC32MM uses the MIPS32 microAptiv core, supporting the MPLAB XC32 compiler toolchain and Harmony/MPLAB Code Configurator (MCC) libraries. Code execution is deterministic thanks to a single-cycle 32-bit ALU and a tightly-coupled peripheral bus. The integrated USB 2.0 full-speed controller supports device, host, and OTG roles with an internal transceiver, eliminating the need for an external PHY in many cost-sensitive designs.
Typical applications include USB Human Interface Devices (HID), wireless sensor node bridges, low-cost consumer USB peripherals, battery-powered IoT endpoints, and industrial sensor monitoring with USB diagnostics. The combination of ECC Flash, deep-sleep current, and integrated USB makes it well suited for safety-conscious and field-upgradable embedded products.
When designing with this MCU, allocate the exposed pad (EP) on the PCB to a continuous ground plane with adequate thermal vias to maintain the device within its 85 °C industrial junction range. Use the PPS system to map peripherals to free pins before finalizing the schematic - incorrect PPS mapping is a common source of 'dead' GPIO on PIC32 designs.

Typische Anwendungen
PIC32MM0256GPM028-I/M6 ist geeignet für 6 Anwendungs: USB HID Peripheral (Keyboard, Mouse, Custom HID), Battery-Powered IoT Sensor Node with USB Diagnostics, USB-to-UART/I2C/SPI Bridge Dongle, Low-Cost Consumer USB Peripheral, Industrial USB Sensor / Data Acquisition Module, USB-Connected Wearable / Fitness Accessory.
USB HID Peripheral (Keyboard, Mouse, Custom HID)
The PIC32MM0256GPM028-I/M6 is well matched to USB HID peripherals thanks to its integrated USB 2.0 full-speed controller with on-chip transceiver, 256 KB ECC Flash to host the Harmony USB stack plus boot-loader, and a small 4x4 mm UQFN footprint that fits inside mouse and keypad enclosures. The 25 MHz MIPS32 microAptiv core runs HID class drivers with low interrupt latency, while the integrated USB eliminates the need for an external PHY. Placed as the system MCU between the USB connector and the sensor/key matrix, it enumerates as HID and handles report generation without an external crystal beyond the standard 48 MHz USB reference. Unlike PIC32MX-based HID designs, the GPM family offers lower active current per MHz which extends battery life in wireless HID dongles.

Battery-Powered IoT Sensor Node with USB Diagnostics
For battery-powered IoT sensor nodes that occasionally expose a USB diagnostic port, the PIC32MM0256GPM028-I/M6 combines deep-sleep current savings (eXtreme low power PIC32MM GPM family) with on-board USB for in-the-field firmware update and log dump. The 256 KB ECC Flash allows a dual-bank boot-loader to safely recover from partial updates over USB, while the 32 KB SRAM buffers sensor bursts before transmission. Placed between the sensor front-end and a low-power RF co-processor, it spends most of its life in deep-sleep and only wakes the USB stack for tethered diagnostics. Compared to PIC32MX, this part offers significantly lower deep-sleep current, extending coin-cell lifetime in remote sensor deployments.

USB-to-UART/I2C/SPI Bridge Dongle
The PIC32MM0256GPM028-I/M6 is a strong fit for USB-to-UART, USB-to-I2C, and USB-to-SPI bridge dongles used in factory test fixtures and embedded developer tools. With integrated USB device, three independent UART/I2C/SPI peripherals, and the peripheral pin select (PPS) system that lets the firmware remap serial interfaces to any GPIO, the same hardware can be re-flashed to support multiple bridge protocols. The 256 KB Flash accommodates full CDC + HID + vendor-class stacks, while the 4x4 mm UQFN keeps the dongle small. Placed at the USB connector end with an ESD-protected USB DP/DM pair, it enumerates as a composite device.

Low-Cost Consumer USB Peripheral
Cost-sensitive consumer USB products (custom game controllers, HID-streaming accessories, USB dongles) benefit from the PIC32MM0256GPM028-I/M6's small UQFN-28 footprint and integrated USB PHY. At 25 MHz the microAptiv core handles HID + vendor-class report traffic with margin, and the 32 KB SRAM comfortably buffers HID input streams. The exposed pad provides a low-impedance thermal path for the modest 3.3 V active current. Placed near the USB-C connector with the EP bonded to a continuous ground plane, the design needs no external USB PHY. Unlike higher-pin-count PIC32MX, this part lets the BOM stay below 50 cents of passive component cost.

Industrial USB Sensor / Data Acquisition Module
Industrial USB data acquisition modules that read sensors and stream data over USB use the PIC32MM0256GPM028-I/M6 to combine 256 KB ECC Flash (for reliability in factory-floor EMI), integrated USB 2.0 full-speed, and a 12-bit ADC plus configurable logic cells for digital signal conditioning. The -40 °C to +85 °C industrial temperature range covers most factory environments, and the QFN-28 EP package dissipates the small active load cleanly. Placed between the analog front-end and the USB connector, it streams samples via CDC or vendor-class endpoints. Compared to PIC32MX, this part's ECC Flash is a tangible reliability advantage for unattended industrial modules.
Empfohlen
USB-Connected Wearable / Fitness Accessory
Wearable fitness accessories that sync to a phone over USB (charging cradle data sync, BLE-USB bridge for setup) take advantage of the PIC32MM0256GPM028-I/M6's small UQFN footprint that fits inside a charging cradle PCB, its low active current to avoid draining the host battery, and its 256 KB Flash that holds both a USB CDC stack and a vendor-class sync protocol. The 32 KB SRAM is sufficient to buffer a week's worth of step-count summaries. Placed on the cradle PCB between the USB-C receptacle and the charging IC, it appears as a composite CDC/MSD device. Unlike PIC24FJ alternatives, this part offers a true 32-bit datapath at comparable cost.

Wichtigste Unterscheidungsmerkmale
- Largest Flash in a 28-pin UQFN PIC32MM GPM part (vs. PIC32MM0128GPM028-I/M6)
- GPM sub-family includes integrated USB 2.0 full-speed (vs. PIC32MM0032GPL028-I/M6)
- ECC-protected Flash for field reliability (vs. PIC32MX250F128B)
Designhinweise
The 28-pin UQFN (4x4 mm) package dissipates the modest 3.3 V active power of a 25 MHz MCU comfortably, but the exposed pad (EP) must be soldered to a continuous ground plane with at least 4 thermal vias to keep theta_JA within the industrial temperature range. Estimated: with EP soldered to a 1 square inch copper pour on a 2-layer FR4 board, theta_JA is approximately 35 °C/W; without the EP land pattern, theta_JA exceeds 80 °C/W and the device may enter thermal shutdown under sustained full-core load.
Route the USB DP/DM traces as a 90-ohm differential pair with matched length (±150 mil) directly from the MCU pins to the USB connector. Place the ESD protection array (such as USBLC6-2SC6) within 3 mm of the connector, and add a 47 nF X7R bypass capacitor on each of VDD and VUSB. Decoupling capacitors should be placed as close as possible to the MCU power pins, with a 0.1 µF and a 1 µF X7R in parallel for high-frequency noise suppression.
Do not skip configuration of the Peripheral Pin Select (PPS) registers in code - the UART, SPI, and I2C peripherals do not have fixed GPIO assignments on PIC32MM, and a missing PPS unlock sequence will leave peripherals silent. Use the MPLAB Code Configurator (MCC) to generate the PPS mapping to avoid manual errors. Also note that the PIC32MM0256GPM028-I/M6 is the industrial temperature variant (-40 to +85 °C); use the -E/M6 suffix for extended temperature designs.
Use a 12 MHz or 24 MHz crystal with appropriate load capacitors as the USB clock source - the USB peripheral requires a precise 48 MHz reference, and an inaccurate crystal will cause USB enumeration failures or intermittent disconnects. The PLL multiplier settings in the device configuration bits must match the chosen crystal. Estimated: load capacitance mismatch greater than 2 pF can pull the USB clock by more than 50 ppm, exceeding the USB 2.0 full-speed accuracy budget.
Compliance-Informationen
RoHS compliant per Microchip product page and distributor listings. EAR99 export classification. Not AEC-Q100 qualified - this is an industrial-temperature MCU (-40 to +85 °C), not an automotive-grade part.
