PIC32MM0064GPL036T-I/MV Overview
An MCU (microcontroller unit) is a single-chip computer that combines a CPU core, non-volatile program memory, working RAM, and a mix of analog/digital peripherals on one die. The PIC32MM0064GPL036T-I/MV belongs to the 32-bit MCU tier (MIPS32 architecture), more capable than 8/16-bit MCUs in DSP and code density, but more power-efficient than application processors. Within Microchip's portfolio, the PIC32MM GPL family sits between the PIC24/dsPIC33 16-bit line and the higher-end PIC32MX/MK families, optimized for cost-sensitive low-power applications.
Key specifications include a 2.0V to 3.6V operating voltage range, 25 MHz maximum core clock, 64 KB Flash (64K x 8), 8 KB SRAM, four 16-bit timers, two I2C, two SPI, and up to two UART interfaces, plus a 12-bit ADC with up to 200 ksps conversion rate and multiple 10-bit PWM outputs. The on-chip 32 kHz low-power oscillator and wide operating temperature range (-40C to +125C) further reinforce its fitness for industrial, IoT, and consumer products.
The microAptiv UC core implements the MIPS32 instruction set with hardware multiply/divide and a 5-stage pipeline that balances deterministic interrupt response with energy efficiency. Combined with Microchip's peripheral remapping architecture (PPS-like flexible pin assignment), designers gain layout freedom on dense boards while keeping firmware modular and reusable across the PIC32MM family.
Typical applications include IoT sensor nodes, battery-powered wearables, low-cost motor control loops, home automation controllers, and industrial sensor hubs. The 25 MHz core with 64 KB Flash easily accommodates connectivity stacks (BLE, LoRa, sub-GHz proprietary), sensor fusion routines, and small TFT GUIs without external memory.
A core design consideration is PCB layout: the UQFN-40 EP package requires a properly stitched ground pad and thermal vias for heat removal at high CPU loads. Decoupling should follow Microchip's guideline - one 100 nF ceramic per VDD pin plus a bulk 10 uF near the regulator - to keep core supply noise below the core's brown-out threshold.

Typical Applications
PIC32MM0064GPL036T-I/MV is suitable for 6 applications: IoT Wireless Sensor Nodes, Battery-Powered Wearable Devices, Low-Cost Motor Control (BLDC / FOC), Home Automation / Smart Home Hubs, Industrial Sensor Hubs, Low-Cost Consumer Electronics.
IoT Wireless Sensor Nodes
The PIC32MM0064GPL036T-I/MV fits IoT wireless sensor nodes because its 25 MHz MIPS32 microAptiv UC core, 64 KB Flash and 8 KB SRAM comfortably host BLE or Sub-GHz proprietary stacks while XLP technology drops quiescent current to roughly 500 nA in deep sleep. The 2.0-3.6 V single-rail supply directly accepts 2x AA or coin cells without a boost converter, and the 12-bit ADC with 200 ksps rate is well matched to common temperature, humidity, and gas sensor outputs. Used as the central MCU between a sensor front-end and a low-power radio, it delivers years of battery life while keeping the BOM lean. Trade-off: the GPL family has no USB, so commissioning is over UART or SWD only.
Recommended
Battery-Powered Wearable Devices
Wearables benefit from the PIC32MM0064GPL036T-I/MV's sub-microamp deep-sleep current and 2.0-3.6 V supply, which let it run for weeks on a small Li-ion cell driving sensors and a small OLED. The 64 KB Flash holds RTOS kernels plus BLE stacks and gesture-detection firmware, while the 12-bit ADC reads heart-rate or motion signals at up to 200 ksps with hardware averaging for noise reduction. PPS-style peripheral remapping makes it easy to route I2C, SPI, and PWM onto the few remaining pins inside a small wearable enclosure. Compared to ARM Cortex-M0+ parts, the GPL gives comparable MIPS-per-milliwatt with Microchip's mature MPLAB X toolchain.
Recommended
Low-Cost Motor Control (BLDC / FOC)
The PIC32MM0064GPL036T-I/MV drives low-power BLDC or small stepper motors thanks to its 25 MHz core, multiple 10-bit PWM channels, and 4 x 16-bit timers that handle center-aligned complementary PWM with dead-time insertion. With 64 KB Flash it fits sensorless or Hall-sensor FOC reference firmware from Microchip's AN1078 family without resorting to larger PIC32MX devices. The 40-UQFN package exposes enough I/O for three-phase gate drivers, fault inputs, and back-EMF sensing through the 12-bit ADC. For cost-sensitive ceiling fans, pumps, and small drones, this MCU delivers the right balance of performance and BOM cost.
Recommended
Home Automation / Smart Home Hubs
Smart-home sensor and actuator hubs benefit from the PIC32MM0064GPL036T-I/MV's mix of 2x I2C, 2x SPI, and 2x UART channels, which let one MCU coordinate multiple radios, sensors, and relay drivers on a single PCB. The 25 MHz core executes Zigbee or Thread-style mesh stacks alongside local control logic, and 64 KB Flash leaves room for secure bootloaders and OTA update partitions. Industrial temperature range -40 C to +125 C supports deployment in unheated attics, garages, and outdoor enclosures. Its XLP sleep current extends battery life for wirelessly-powered push-buttons and door sensors that must run for years.
Recommended
Industrial Sensor Hubs
Industrial sensor hubs use the PIC32MM0064GPL036T-I/MV because its -40 C to +125 C rating and 2.0-3.6 V supply tolerate factory-floor transients and 24 V-to-3.3 V regulator rails with margin. The 12-bit ADC at 200 ksps aggregates readings from multiple 4-20 mA loop sensors through external signal conditioning, while the 4 x 16-bit timers handle pulse counting for flow meters and encoders. 64 KB Flash is enough for Modbus RTU slave firmware plus diagnostic logging. Designers often pair this MCU with a small isolation barrier (digital isolator or RS-485 transceiver) to meet IEC 61131-2 industrial requirements.
Recommended
Low-Cost Consumer Electronics
Mass-market consumer products - remote controls, small appliances, toys, and personal care devices - rely on the PIC32MM0064GPL036T-I/MV for its sub-$1 price at volume combined with real 32-bit performance. The 64 KB Flash accommodates capacitive-touch libraries and small graphics firmwares, while the 10-bit PWM channels drive LEDs, buzzers, and small DC loads without extra driver ICs. Deep-sleep currents near 500 nA let battery-powered devices sit on a shelf for a year or more without replacement. The 40-UQFN 5x5 mm footprint fits inside enclosures as small as a TV remote or an electric toothbrush.

Key Differentiators
- Lowest-cost 32-bit XLP option in the PIC32MM family with 64 KB Flash in 40-UQFN (vs PIC32MM0064GPM036-I/MV)
- Industrial temperature grade in T&R packaging (vs PIC32MM0064GPL036-I/MV (tray))
- 64 KB Flash at 25 MHz vs 16-bit PIC24F at the same price (vs PIC24HJ64GP502-I/SO)
Design Notes
Estimated: the 40-UQFN exposed pad must be soldered to a continuous ground copper pour with at least 4 thermal vias (0.3 mm drill, 0.5 mm pitch) under the EP for proper thermal and electrical performance. Place a 100 nF X7R ceramic decoupling capacitor on every VDD pin within 2 mm, plus one bulk 10 uF ceramic near the 3.3 V regulator. Keep the ICSP PGECx/PGEDx traces shorter than 50 mm and away from switching nodes to preserve clean in-circuit programming.
Estimated: at 25 MHz and 3.3 V with all peripherals active, the PIC32MM0064GPL036T-I/MV draws roughly 8-10 mA, so a 3.3 V LDO rated for at least 50 mA with 100 mV dropout at 10 mA (e.g., MCP1700) is recommended. For battery-powered designs, switch the MCU core clock to the internal 8 MHz oscillator before sleep and gate peripheral power domains through MOSFETs to push quiescent current toward the 500 nA deep-sleep spec.
Do not assume every PIC32MM GPL variant has the same peripheral mix - the 036 suffix carries 64 KB Flash while 028/020 shrink Flash and pin count. Brown-out resets must be enabled and the BOR voltage set to match the minimum operating rail (2.0 V); otherwise, voltage dips during TX bursts can corrupt Flash or freeze the CPU. When migrating from PIC24/dsPIC33, verify that PPS assignments are re-mapped, since pin function registers are not bit-compatible across families.
Compliance Information
RoHS and REACH compliance per Microchip PIC32MM product page. Industrial -40 C to +125 C grade (no AEC-Q100); choose PIC32MMxxxGPM family variants for AEC-Q100 qualified automotive designs.
