PIC32MM0128GPM048-E/PT 개요
A 32-bit microcontroller (MCU) is an integrated circuit that combines a 32-bit CPU core, program memory (Flash), data memory (SRAM), and a rich set of peripherals on a single silicon die. Microcontrollers sit at the heart of embedded systems, sitting one tier above simple 8/16-bit MCUs and one tier below application processors. The PIC32MM GPM family extends Microchip's PIC32MX heritage with microAptiv core enhancements for low-power, mixed-signal applications and provides a smooth upward migration path from smaller PIC32MM variants and from legacy PIC24/PIC32MX designs.
Key features of the PIC32MM0128GPM048-E/PT include: 128 KB (128K x 8) ECC Flash, 16 KB SRAM, USB 2.0 full-speed device, 79 CoreMark performance, multiple low-power sleep modes typical of the eXtreme low power family, and an industrial-grade peripheral set including 12-bit ADC, comparators, timers, UART/SPI/I2C, and PMP. The 48-pin TQFP-EP exposes a substantial ground pad for thermal dissipation and offers ample GPIO for connectivity.
The microAptiv core implements the MIPS32 instruction set with hardware multiply/divide and a tightly-coupled interrupt controller, achieving 79 CoreMark at 25 MHz while remaining in a low active-power envelope. ECC on Flash improves reliability in industrial environments exposed to single-event upsets, and the on-chip USB 2.0 full-speed device controller simplifies connectivity for HID, CDC, vendor-class, or custom USB peripherals.
Typical applications include low-power USB peripherals, IoT sensor nodes, industrial sensor interfaces, home automation gateways, and battery-powered consumer devices. The wide 3.0-3.6 V supply range is well matched to both Li-Ion and regulated 3.3 V rails.
When designing with this part, prefer the exposed pad (EP) connected to a continuous ground plane for both thermal relief and signal integrity. For USB designs, follow the USB transceiver PCB guidelines for 90-ohm differential impedance and ensure VUSB 3.3 V is well decoupled.

설계 노트
Connect the 48-TQFP-EP exposed thermal pad to a continuous ground plane with at least 9 thermal vias (0.3 mm drill, 0.6 mm pad) for both thermal dissipation and low-inductance ground. Per Microchip AN-1267, this is required for reliable operation in extended temperature (E) variants. Keep high-speed USB traces (D+/D-) at 90 ohms differential and route over a continuous ground reference plane.
Decouple each VDD pin with a 100 nF ceramic capacitor placed within 2 mm of the pin; add a bulk 4.7 uF capacitor near the MCU. VUSB requires its own 100 nF plus a 4.7 uF bulk per Microchip USB hardware design guidelines. Failing to decouple VUSB independently can cause USB enumeration failures even if VDD is clean. Use ferrite beads if the USB bus is shared with noisy regulators.
Do not leave unused pins floating; configure them as digital outputs or inputs with the internal weak pull-up enabled. Floating analog pins (ANx) can cause shoot-through current in the analog mux and degrade ADC accuracy. Always set the JTAG/ICSP pins (PGECx/PGEDx) to their debug configuration before programming, or use the ICSP pairs explicitly (PGEC2/PGED2, etc.) as noted in the datasheet.
Route USB D+ and D- as a 90-ohm differential pair with matched lengths (<2 mm skew) and no stubs. Place the common-mode choke and ESD protection array within 5 mm of the USB connector. Avoid running the USB pair near switching regulator inductors or other noisy traces; cross only at 90 degrees if necessary. Keep the USB shield ground connection to the board ground within 5 mm of the connector entry.
