PIC32MM0032GPL020-I/SS Übersicht
The PIC32MM "GPL" family is positioned as Microchip's lowest-power 32-bit MCU line, delivering eXtreme Low Power (XLP) sleep modes down to 500 nA for battery-driven applications. A 32-bit microcontroller (MCU) is a microprocessor-on-a-chip that combines a wide data-path CPU core, on-chip Flash program memory, SRAM data memory, and a rich peripheral set; the PIC32MM family specifically targets migration paths from 16-bit PIC24 and earlier PIC32MX designs into a more power- and cost-efficient 32-bit platform.
Key features include 79 CoreMark performance at 25MHz, 1.4 KB data EEPROM, an integrated 12-bit ADC with up to 9 channels, and Core Independent Peripherals (CIPs) that allow hardware-based state machine operation without CPU intervention. The 20-pin SSOP (0.209", 5.30mm body) package supports compact PCB layouts, and the industrial -40C to +85C operating range covers commercial and industrial deployments.
Typical applications include IoT sensor nodes, low-power handheld instrumentation, building automation, lighting control, and consumer white-goods user interfaces. The eXtreme Low Power modes make it especially suitable for battery-powered devices where shutdown current is critical.
When designing with this MCU, plan GPIO and peripheral assignments carefully because the 20-pin SSOP package limits available I/O compared to the 28- or 36-pin PIC32MM GPL variants. Decoupling must include a 0.1 uF ceramic capacitor on each VDD/VSS pair placed within 5mm of the pins, and unused pins should be configured as outputs to reduce sleep current.

Typische Anwendungen
PIC32MM0032GPL020-I/SS ist geeignet für 6 Anwendungs: Battery-Powered IoT Sensor Nodes, Building Automation Controllers, Low-Power Handheld Instrumentation, Consumer White-Goods User Interfaces, LED Lighting Control, Industrial Sensor Hubs.
Battery-Powered IoT Sensor Nodes
The PIC32MM0032GPL020-I/SS is well suited to battery-driven wireless sensor nodes because its XLP sleep current drops to 500 nA, extending coin-cell life to months. With 32 KB Flash and 8 KB SRAM, the MCU comfortably fits BLE/Sigfox/LoRaWAN protocol stacks plus sensor drivers, while the 12-bit ADC and 2 comparators support direct analog front-end connection. Placed on a sensor PCB with a 0.1 uF decoupling capacitor array, it can wake from sleep, sample, transmit, and return to deep sleep at microamp-level average current.
Empfohlen
Building Automation Controllers
The PIC32MM0032GPL020-I/SS integrates UART, SPI, and I2C for connecting to HVAC actuators, lighting ballasts, and occupancy sensors, while its 8 PWM channels support LED dimming or fan-speed control. The 25 MHz microAptiv UC core runs 79 CoreMark, sufficient for BACnet or Modbus framing, while industrial -40C to +85C operation handles basement and rooftop enclosures. Compared with discrete 8-bit designs, this MCU simplifies BOM by combining RTC, WDT, and ADC on one die.
Empfohlen
Low-Power Handheld Instrumentation
Handheld meters benefit from the PIC32MM0032GPL020-I/SS's combination of 12-bit ADC for sensor readout, 32 KB Flash for calibration tables, and 500 nA sleep current for shelf-life. The 20-pin SSOP package fits inside slim handheld enclosures and the RTCC allows timestamping of measurement logs. Power dissipation remains well below 100 mW even at full CPU load, eliminating the need for a heatsink in compact plastic housings.
Empfohlen
Consumer White-Goods User Interfaces
Appliance control panels leverage the PIC32MM0032GPL020-I/SS to scan capacitive touch buttons, drive 7-segment or LED indicators, and run a small UI state machine. The 8 PWM channels control LED brightness and buzzer volume, while the 12-bit ADC reads analog inputs such as NTC thermistors. The 5.30 mm SSOP body drops onto compact keypad PCBs common in washing machines, dishwashers, and microwave ovens.
Empfohlen
LED Lighting Control
The PIC32MM0032GPL020-I/SS drives up to 8 PWM channels simultaneously, allowing multi-channel RGBW or tunable-white LED control from a single MCU. XLP modes make it viable for line-powered lighting with standby power budgets below 100 mW. The 25 MHz CPU bandwidth runs DMX-512 or DALI soft-modems, and the SSOP package fits inside bulb-base controller modules where PCB area is constrained to a few square centimeters.
Empfohlen
Industrial Sensor Hubs
Industrial sensor hubs benefit from the PIC32MM0032GPL020-I/SS's -40C to +85C industrial temperature range and its mix of UART, SPI, and I2C for multi-protocol sensor aggregation. With 8 KB SRAM it can buffer multiple sensor streams before forwarding them over a higher-bandwidth uplink. The 12-bit ADC and 2 analog comparators also handle discrete threshold detection without external op-amps, reducing BOM and PCB area in DIN-rail modules.

Wichtigste Unterscheidungsmerkmale
- XLP sleep current down to 500 nA (vs. PIC32MX1xx/2xx)
- 32 KB Flash with full peripheral set in 20-pin SSOP (vs. PIC32MM0016GPL020-I/SS)
- Industrial -40C to +85C with optional extended grade (vs. PIC32MM0016GPL020-I/SS)
Designhinweise
Place a 0.1 uF ceramic decoupling capacitor within 5 mm of every VDD/VSS pin pair on the PIC32MM0032GPL020-I/SS. For designs that spend significant time in sleep, add a 10 uF bulk capacitor near VDD to support wake-up inrush currents. Do not connect the USB VBUS pin (pin 8) directly to VDD if the application is not USB-powered; leave it floating or tied through a resistor divider to avoid back-powering the bus.
Estimated: at 25 MHz full-load CPU and 3.3 V supply, the PIC32MM0032GPL020-I/SS core current is approximately 6 mA (about 20 mW dissipation). In the 20-SSOP package with typical 80 C/W theta_JA on a 1-oz 2-layer board, junction rise is well below 5 C above ambient. No heatsink is required, but minimum 50 mm^2 of copper pour tied to VSS is recommended to keep junction temperature low in enclosed housings.
Unused GPIO pins on PIC32MM0032GPL020-I/SS must be configured as digital outputs driving low to minimize sleep current; leaving them as analog inputs or floating can add several microamps per pin and break the 500 nA XLP sleep budget. Also ensure the ICSP pins (RB6/RB7 and RA0/RA1) are not driven externally during reset, or debug entry will be blocked. Finally, when migrating from PIC32MX, verify that the PPS (Peripheral Pin Select) mapping is re-applied - the PIC32MM GPL family uses fixed peripheral pin mapping, not PIC32MX-style PPS.
Compliance-Informationen
Standard /I variant is not AEC-Q100 qualified - choose PIC32MM0032GPL020-I/SSVAO for automotive screening. RoHS/REACH compliant per Microchip product page.
