PIC32MM0032GPL028T-I/M6 Visão geral
A 32-bit microcontroller (MCU) is an embedded computing device whose central processing unit has a 32-bit data path, instruction word, and address space, allowing it to handle larger data structures and richer peripherals than 8- or 16-bit parts. The PIC32MM family specifically targets applications that need 32-bit performance without the cost of higher-end Cortex-M parts; within the broader Microchip taxonomy it sits below the PIC32MX/MZ lines and above the 16-bit PIC24/dsPIC families.
Key features of the PIC32MM0032GPL028 include a 3.3 V core supply range (2.5 V to 3.6 V operating), 4 KB of auxiliary Flash (boot/data), up to 21 general-purpose I/O pins, multiple communication peripherals, and an integrated core timer and RTCC. The eXtreme Low Power (XLP) modes with sub-microamp sleep currents make it well suited to coin-cell or energy-harvesting designs. Hardware multipliers, a single-cycle MAC, and MIPS16e code compression further improve code density and execution efficiency.
Typical applications include low-power IoT sensor nodes, wearable health devices, remote controls, e-metering, battery-backed security panels, and small home appliances where a 4 x 4 mm footprint and deep sleep current are decisive. Designers migrating from PIC24 or 16-bit PIC parts gain a 32-bit data path and richer peripherals while keeping the familiar MPLAB X toolchain. When designing with this MCU, budget decoupling capacitance close to both VDD pins and bond the exposed pad to a continuous ground plane to keep the silicon junction within the -40 C to +85 C industrial range.

Aplicações típicas
PIC32MM0032GPL028T-I/M6 é adequado para 6 aplicaçãos: Low-Power IoT Sensor Nodes, Wearable Health and Fitness Devices, Remote Controls and Home Automation, Battery-Backed Security Panels, Electronic Metering (e-Metering), Small Home Appliances.
Low-Power IoT Sensor Nodes
The PIC32MM0032GPL028T-I/M6 fits IoT sensor-node designs thanks to its 32-bit MIPS core at 25 MHz combined with XLP sleep currents down to ~500 nA per the Microchip PIC32MM GPL family datasheet (DS60001392). The 32 KB Flash accommodates small wireless MAC stacks (LoRaWAN, BLE beacon firmware) while the 8 KB SRAM buffers sensor data between radio transmissions. Placed on a 4 x 4 mm UQFN footprint with the exposed pad bonded to ground, the MCU keeps total BOM area under 16 mm^2 including decoupling.
Recomendado
Wearable Health and Fitness Devices
The PIC32MM0032GPL028T-I/M6 is well suited for wearable health monitors because the 32-bit microAptiv core processes motion-sensor data (accelerometer + gyroscope fusion) at 25 MHz while the deep-sleep current keeps coin-cell battery life measured in months per the Microchip PIC32MM GPL family datasheet (DS60001392). The 28-pin UQFN footprint leaves board space for an analog front-end and BLE radio module. Hardware MAC and single-cycle multiply accelerate DSP-style fitness algorithms without offloading to an external coprocessor.
Recomendado
Remote Controls and Home Automation
The PIC32MM0032GPL028T-I/M6 suits IR/RF remote controls and home-automation keypads because the 32-bit core runs proprietary RF protocols or IR encoders while the XLP sleep current extends battery life beyond 5 years on a pair of AAA cells per the Microchip PIC32MM GPL family datasheet (DS60001392). The 21 GPIOs handle a matrix keypad plus status LEDs and an IR emitter without external glue logic. Compared to legacy 8-bit PIC10/12 parts, the 32-bit data path speeds up packet formation for sub-GHz transceivers.
Recomendado
Battery-Backed Security Panels
The PIC32MM0032GPL028T-I/M6 fits battery-backed intrusion and fire-alarm panels thanks to its 32-bit throughput for AES-128 encryption of wireless sensor traffic while the deep-sleep current preserves backup battery life per the Microchip PIC32MM GPL family datasheet (DS60001392). The auxiliary 4 KB Flash block stores calibration constants and event logs without external EEPROM. The exposed-pad UQFN-28 keeps the main board compact while still dissipating the modest power drawn by the security MCU.
Recomendado
Electronic Metering (e-Metering)
The PIC32MM0032GPL028T-I/M6 serves e-metering endpoints (water, gas, electricity sub-meters) because the 32-bit MIPS core computes energy/pulse totals at 25 MHz while XLP sleep keeps idle draw near zero per the Microchip PIC32MM GPL family datasheet (DS60001392). The auxiliary Flash holds tamper logs, and the integrated RTCC provides time-of-day without an external crystal on low-accuracy modes. The 28-pin UQFN package fits inside a sealed meter housing alongside the sensor front-end and isolated communication interface.
Recomendado
Small Home Appliances
The PIC32MM0032GPL028T-I/M6 powers small home appliances such as coffee makers, blenders, and countertop ovens because the 32-bit core drives touch sensing, motor control, and an LCD character display while the 21 GPIOs interface buttons and LED indicators per the Microchip PIC32MM GPL family datasheet (DS60001392). Compared with 8-bit PIC16 alternatives, the 32-bit data path executes touch-sensing libraries faster and supports more complex state machines for safety timers. The 32 KB Flash fits an MPLAB Harmony 3 application plus a bootloader.

Notas de projeto
Place a 100 nF decoupling capacitor within 2 mm of each VDD pin and a bulk 4.7 uF to 10 uF tantalum or ceramic near the package. The UQFN-28 exposed pad must be soldered to a continuous ground plane stitched with thermal vias to keep junction temperature within the -40 C to +85 C industrial range per the Microchip PIC32MM GPL family datasheet (DS60001392). Estimated: thermal resistance theta_JA on the standard 4-layer JEDEC test board is approximately 30 C/W; design margin should keep total dissipation under 0.3 W for unattended-appliance use cases.
Do not confuse the I/M6 (industrial-grade, UQFN-28) suffix with the I/SO (industrial-grade, SOIC-28) suffix - the pinouts are identical but the PCB land pattern differs, so PCB swap-in requires a layout change. Also note that PIC32MM0032GPL020 variants come in 20-pin packages and cannot be substituted on the 28-pin UQFN board. The MPLAB ICD 4 / PICkit 4 debugger connects to PGECx/PGEDx pins (typically RPC0/RPC1 in the UQFN package) and must not be assigned conflicting peripheral functions at runtime.
The PIC32MM0032GPL028T-I/M6 supports XLP sleep modes down to roughly 500 nA per the Microchip PIC32MM GPL family datasheet (DS60001392). Estimated: enabling brown-out reset (BOR) and watchdog timer adds ~1-2 uA; disable unused peripherals in each sleep wake cycle. For sub-uA standby, switch the main regulator to a low-Iq LDO such as MCP1700 (typical Iq 1.6 uA) and gate the sensor supply rails separately from a high-side load switch.
The PIC32MM0032GPL028T-I/M6 is rated for 25 MHz core clock; routing external signals above 25 MHz requires impedance-controlled traces and series termination on high-drive GPIO lines per the Microchip PIC32MM GPL family datasheet (DS60001392). For I2C buses above 400 kHz, add 4.7 kohm pull-ups instead of the default 10 kohm, and place the pull-ups within 20 mm of the MCU. The SCL/SDA lines benefit from a small ferrite bead if the bus leaves the board.
Informações de conformidade
RoHS compliant per Microchip product page. AEC-Q100 grade is not applicable - the I/M6 suffix denotes industrial temperature grade (-40 C to +85 C); automotive-grade variants exist in the wider PIC32MM GPL family but use a different suffix.
