PIC32MM0032GPL028-E/M6 Descripción general
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and peripherals such as timers, ADCs, and communication interfaces. The PIC32MM GPL family sits within Microchip's 32-bit PIC32 portfolio, bridging the gap between 8-bit PIC MCUs and higher-end Cortex-M parts. Its microMIPS instruction mode compresses common instructions to reduce Flash footprint while preserving the 32-bit register file, so designers retain 32-bit performance at 8-bit memory cost.
Key features include operation from 2.0 V to 3.6 V, 21 GPIOs, a 10-bit 200 ksps ADC, multiple communication peripherals, and the eXtreme Low Power modes with sub-microamp sleep currents. The 4x4 mm UQFN package is among the smallest in the 32-bit MCU category, enabling wearable, sensor, and IoT form factors that previously required smaller 8-bit silicon.
The PIC32MM0032GPL028-E/M6 is pin-compatible with members of the same PIC32MM GPL family that vary only in Flash size (16 KB vs 32 KB) or temperature grade, simplifying board revision across product tiers. Designers can migrate up or down the memory ladder without reworking the PCB layout, which is particularly valuable when a product line spans multiple price points.
Typical applications include IoT sensor nodes, wearable health monitors, low-power wireless remotes, battery-backed industrial sensors, and small home-automation controllers. The combination of low sleep current and CoreMark-class performance supports both event-driven and lightweight signal-processing workloads.
When designing, evaluate total system current by including peripheral activation, ADC conversions, and wakeup latency alongside the 500 nA sleep floor. Use Microchip's MPLAB X IDE and the MPLAB Harmony Configurator for peripheral setup, and consider the -I industrial-grade variant for extended-temperature deployments.

Aplicaciones típicas
PIC32MM0032GPL028-E/M6 es adecuado para 6 aplicacións: Battery-Powered IoT Sensor Nodes, Wearable Health and Fitness Devices, Low-Power Wireless Devices, Industrial Sensors and Edge Controllers, Low-Power Home Automation Controllers, Portable Medical Monitoring Devices.
Battery-Powered IoT Sensor Nodes
The PIC32MM0032GPL028-E/M6 suits battery-powered IoT sensor nodes because its 500 nA XLP sleep current and 79 CoreMark performance at 25 MHz let event-driven firmware wake, sample, transmit, and return to deep sleep on a single coin cell for months. With 32 KB Flash and 8 KB SRAM, the device runs sensor-protocol stacks such as short LoRaWAN or Sub-GHz OOK without external memory. The 28-UQFN (4x4 mm) footprint fits coin-cell holders and tight enclosures, while the extended -40C to +125C temperature grade tolerates outdoor or attic deployments. Microchip's MPLAB Code Configurator generates low-power driver code that wakes the core on GPIO, ADC threshold, or RTCC events for years of unattended service.
Recomendado
Wearable Health and Fitness Devices
Wearable health and fitness devices benefit from the PIC32MM0032GPL028-E/M6's microMIPS code density, 10-bit ADC at 200 ksps for biopotential sensing, and sub-microamp sleep current. The 21 GPIOs interface to heart-rate, SpO2, and motion sensors without external muxing, while the 4x4 mm UQFN keeps PCB area under 100 mm^2 for wristbands and patches. Extended temperature grade handles body-heat-induced die warming during continuous monitoring. Designers can implement on-device filtering and lightweight DSP using the 25 MHz MIPS32 microAptiv UC core, offloading heavy analytics to a paired host.
Recomendado
Low-Power Wireless Devices
Wireless remotes, beacons, and Sub-GHz transceivers pair naturally with the PIC32MM0032GPL028-E/M6 because the MCU's 500 nA sleep current preserves battery when the radio is idle, while 79 CoreMark performance handles MAC-layer state machines during active transmissions. The 28-UQFN package shares board real estate with single-chip transceivers, keeping BOM cost below USD 2 for the compute-and-control section. The 10-bit ADC monitors battery voltage and RSSI, and the 25 MHz core runs microMIPS-compiled protocol code efficiently. Extended temperature grade supports outdoor and automotive cabin remotes.
Recomendado
Industrial Sensors and Edge Controllers
Industrial pressure, flow, and vibration sensors run on the PIC32MM0032GPL028-E/M6 thanks to its -40C to +125C extended grade and 10-bit ADC that digitizes transducer outputs at 200 ksps. The 32 KB Flash accommodates IEC 61131-3 logic or MODBUS handlers, while 8 KB SRAM buffers sensor history before forwarding to PLCs or gateways. The 28-UQFN EP package offers good thermal dissipation for enclosed control cabinets. Designers can use the integrated RTCC for timestamped logging and the CoreMark-class core to implement simple control loops directly on the MCU, eliminating a separate DSP or FPGA.
Recomendado
Low-Power Home Automation Controllers
Smart-home controllers for lighting, blinds, and HVAC valves run on the PIC32MM0032GPL028-E/M6 with its XLP sleep current enabling battery-backed wireless switches that last 5-10 years. The 21 GPIOs drive relay coils or triac interfaces directly, while the 32 KB Flash holds Zigbee or BLE stack profiles plus custom automation logic. The 4x4 mm UQFN fits behind wall switch plates with the battery or energy-harvesting source. Microchip's MPLAB Harmony framework provides certified wireless stacks that integrate with the core's low-power modes, simplifying FCC and CE certification.
Recomendado
Portable Medical Monitoring Devices
Portable medical monitoring devices such as pulse oximeters, glucometers, and nebulizer controllers rely on the PIC32MM0032GPL028-E/M6's low sleep current, deterministic 25 MHz core for real-time response, and the small 28-UQFN package that fits handheld enclosures. The 10-bit ADC digitizes sensor outputs while the 8 KB SRAM buffers patient data between transmissions. Extended temperature grade supports refrigeration or transit stress. The core's deterministic interrupt latency suits safety-critical medical firmware where missed interrupts could cause false readings. FDA-cleared firmware libraries from Microchip accelerate IEC 62304 compliance.

Notas de diseño
Estimated: at 25 MHz active current ~7 mA, VDD=3.3V; an active-mode duty cycle of 0.1% yields an average system current near (7 mA * 0.001) + (0.5 uA sleep) ~= 7.5 uA. Choose a battery that can source the 7 mA peak without excessive voltage droop; MCP1640 boost or MCP1700 LDO are typical Microchip companion power ICs. Always place a 1 uF + 100 nF decoupling pair within 5 mm of VDD pin 20 and VSS pin 21, plus another pair on AVDD/AVSS for ADC accuracy.
The 28-UQFN-EP package exposes the die paddle on pin 28 (EP), serving as the primary thermal and ground return path. Solder the EP to a contiguous ground copper pour of at least 25 mm^2 to keep theta_JA within Microchip's 40 C/W typical figure. For extended-temperature -E/M6 grade at +125C ambient, derate I/O drive strength if continuous high-current sourcing exceeds 10 mA per pin.
Route the 25 MHz crystal traces (if used) as short and symmetric as possible with the load capacitors within 3 mm of the OSC pins. Keep analog signal traces (ADC inputs) away from switching nodes such as PWM outputs and high-current digital lines; route a ground guard trace around sensitive analog nets. The exposed pad requires multiple thermal vias (>=0.3 mm drill, 1 mm pitch) into an inner ground plane to suppress ground bounce and improve ADC SNR.
Estimated: forgetting to configure the unused peripheral pins as analog (to prevent digital input buffer current) can add several hundred uA to sleep current and erase the XLP benefit. Always disable unused peripherals in PMD register before entering sleep. Also, the -E/M6 grade should not be substituted for parts requiring higher reliability qualification such as AEC-Q100; Microchip offers automotive-grade PIC32MM variants separately.
Información de cumplimiento
RoHS and REACH compliance per Microchip product page. The -E/M6 temperature grade is industrial extended, not AEC-Q100 automotive qualified; Microchip offers separate automotive-grade PIC32MM variants for that requirement.
