PIC32MM0128GPM048-E/PT 概要

The Microchip PIC32MM0128GPM048-E/PT is a 32-bit MIPS32 microAptiv PIC microcontroller running at 25 MHz with 128 KB of Flash and 16 KB of SRAM, packaged in a 48-pin TQFP-EP (7x7 mm) with exposed thermal pad. As part of the eXtreme low power PIC32MM GPM family, it adds USB 2.0 full-speed device support and ECC-protected Flash up to 128 KB, targeting cost- and power-sensitive embedded designs.

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.

This page synthesizes distributor pricing, drop-in same-package alternatives, and practical low-power and USB design notes not found in the manufacturer datasheet alone.

Choose the PIC32MM0128GPM048-E/PT when you need Microchip’s MPLAB X toolchain, Harmony 3 support, eXtreme low-power sleep modes, and a stable long-life MCU with automotive pedigree. Choose STM32 (e.g. STM32G0/G4) when you need higher MHz, larger RAM, or DMA-heavy peripherals. The PIC32MM is more competitive on power efficiency and ecosystem familiarity for PIC24/PIC32MX migrations.
Is PIC32MM0128GPM048-E/PT suitable for USB HID peripherals?
Yes. The PIC32MM0128GPM048-E/PT integrates USB 2.0 full-speed device with on-chip transceiver, suitable for HID, CDC, vendor-class, and composite devices. The 128 KB Flash easily fits HID + CDC stacks, and 16 KB SRAM accommodates USB endpoint buffers plus application memory. Microchip’s USB framework in MPLAB Harmony 3 simplifies enumeration.
What key specifications of PIC32MM0128GPM048-E/PT should engineers know?
The PIC32MM0128GPM048-E/PT combines a 32-bit MIPS32 microAptiv core at 25 MHz (79 CoreMark), 128 KB ECC Flash, 16 KB SRAM, USB 2.0 FS device, 48-TQFP-EP package, 3.0-3.6 V VDD, and -40C to +125C extended temperature range. According to the Microchip PIC32MM GPM family datasheet, these parameters make it a low-power, USB-capable MCU for cost-sensitive embedded applications.

エンジニアリング参考データ: PIC32MM0128GPM048-E/PT — 比較、設計ガイダンス、コンプライアンス情報。

選定ガイド

Choose the PIC32MM0128GPM048-E/PT when you need 128 KB ECC Flash, USB 2.0 FS device, and extended -40C to +125C temperature in a 48-TQFP-EP package, especially for USB peripherals, industrial sensors, or battery-powered consumer devices that must survive harsh environments. Choose the PIC32MM0128GPM048-I/PT (-40C to +85C) if your design runs only in commercial/industrial temperature and you want identical silicon at slightly lower cost. Choose the PIC32MM0064GPM048T-I/M4 (48-TQFP-EP, 64 KB Flash) for cost-sensitive designs where 64 KB suffices and you can drop the E temperature grade. Avoid specifying PIC32MK parts in 48-TQFP-EP layouts — they require 100-TQFP and are NOT drop-in compatible.

  • Lower power profile than PIC32MK (vs PIC32MK1024MCM100-E/PT)

設計ノート

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.
