PIC32MM0128GPM036T-I/M2 Visão geral
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, RAM, non-volatile program memory, and peripheral interfaces on one die. The PIC32MM GPM family is Microchip's eXtreme low-power 32-bit PIC32 line, positioned as a cost-effective migration path between 16-bit PIC24/dsPIC devices and higher-end PIC32MX/MZ parts. The microAptiv core adds microMIPS code compression and DSP extensions, while the GPM family specifically adds USB and ECC memory up to 128 KB.
Key features include 21 timers, a 4-channel DMA controller, 3 analog comparators, a 12-bit ADC with up to 1 MSPS, a 5-bit DAC, and communication peripherals covering I2C, SPI, UART, LIN, and USB. The 36-pin SQFN package exposes 25+ general-purpose I/O lines and supports segmented LCD bias generation. ECC on Flash improves reliability for industrial and safety-sensitive applications, and deep sleep current is specified in the microampere range for battery operation.
Typical applications include low-power USB HID/CDC devices, sensor hubs, industrial sensor nodes, IoT end nodes with USB debugging, home automation controllers, and motor control peripheral front-ends. The USB on-chip controller eliminates an external interface chip, and the integrated 12-bit ADC supports direct sensor signal conditioning without a separate ADC IC.
When designing with this part, validate that the 36-pin SQFN land pattern is routable on your PCB and that the exposed thermal pad is soldered for reliable thermal performance. Use MPLAB X IDE with XC32 compiler and MPLAB Harmony framework for firmware development; the device is supported by Microchip's standard PIC32 toolchain.

- Pin-compatible Flash upgrade path within same family (vs PIC32MM0256GPM036T-I/M2)

Notas de projeto
The PIC32MM0128GPM036T-I/M2 has separate analog and digital supply pins (VDD/VSS) that should be decoupled with 100 nF and 4.7 uF capacitors placed as close as possible to each supply pin. For USB bus-powered designs, the VUSB pin requires a 1 uF decoupling capacitor to ground. Use a star-ground topology with the exposed thermal pad tied to ground for optimal thermal dissipation and EMI performance.
Route USB D+ and D- traces as a 90-ohm differential pair with matched length within 300 mil, and place the 27 pF series capacitor near the connector on the MCU side per USB 2.0 spec. Keep crystal traces (OSC1/OSC2) short and surrounded by ground pour to avoid coupling noise into the system clock. Place the SQFN exposed pad on the bottom copper plane with multiple thermal vias for heat spreading.
Estimated: at maximum sustained CPU activity (48 MHz, full peripheral clock) the SQFN-36 junction temperature rise above ambient is approximately 8-12C/W depending on copper area; with 1 square inch of ground plane on the exposed pad, theta_JA is around 38 C/W. For continuous heavy compute, attach the exposed pad to a copper pour with at least 4-6 thermal vias to limit junction temperature below 100C in industrial environments.
Do not exceed 3.6 V on any I/O or supply pin - the PIC32MM is not 5 V tolerant. Verify the USB VBUS voltage does not exceed 3.6 V before connecting to VUSB; many bus-powered designs require external protection. The CONFIG words must be programmed correctly to enable the USB clock source or USB enumeration will fail. Enable the JTAG lock bits for production to protect firmware IP.
