PIC32MM0064GPL020T-I/ML - 32-bit 25MHz 64KB Flash MCU | Microchip
MPN: PIC32MM0064GPL020T-I/ML ✓ Hoạt độngPIC32MM0064GPL020T-I/ML Tóm tắt
A 32-bit microcontroller (MCU) is a single-chip processor integrating CPU core, Flash program memory, SRAM data memory, and peripherals such as timers, ADC, communication interfaces, and GPIO into one package. The PIC32MM family in particular targets eXtreme Low Power (XLP) applications where battery life and standby current dominate the design budget, while delivering 32-bit MIPS performance at the cost of an 8-bit MCU. The 'GPL' sub-family combines this low-power DNA with general-purpose peripherals for cost-sensitive embedded designs.
Key features of the PIC32MM0064GPL020T-I/ML include 25 MHz core speed (38 DMIPS), 64 KB Flash with 4 KB SRAM, multiple low-power modes including 500 nA Deep Sleep, 9-channel 12-bit ADC, three op-amps, and configurable peripherals via Peripheral Pin Select (PPS). The 20-pin QFN (4x4 mm) package provides the smallest form factor in the family while exposing a thermal pad for improved power dissipation.
Architecturally, the MIPS32 microAptiv core uses a 5-stage pipeline with branch prediction and zero overhead loop support, while on-chip peripherals include 12-bit ADC, comparators, configurable logic cells, and PWM/IC/OC timers. The integrated op-amps and configurable logic reduce external component count for sensor-interface and motor-control designs. The 'GPL' part is the general-purpose variant; the 'GPM' variant adds motor-control PWMs, and the 'GPS' variant adds segmented LCD drivers.
Typical applications include battery-powered IoT sensor nodes, wearable health monitors, low-cost motor control, touch-interface front-ends, and space-constrained consumer electronics. The 500 nA sleep current suits coin-cell designs such as BLE beacons, environmental sensors, and remote controls.
Design consideration: the 20-pin QFN (4x4 mm) requires careful PCB thermal-via stitching under the exposed pad to keep junction temperature within the -40C to +85C industrial range. At full 25 MHz operation with peripherals active, decoupling with 100 nF ceramic caps placed within 2 mm of VDD pins is essential for stable ADC sampling.

Ghi chú thiết kế
The PIC32MM0064GPL020T-I/ML Deep Sleep mode draws only 500 nA typical, but achieving this requires proper configuration: disable all unused peripherals via PMD registers, set all unused I/O pins to digital outputs driving low (not high-Z), and ensure ADC is powered down between conversions. Estimated: a typical sensor-node application waking every 10 seconds for 50 ms measurements achieves average current of under 5 uA, giving 5+ years on a 1000 mAh coin cell.
The 20-pin 4x4 mm QFN package with exposed pad requires PCB thermal-via stitching directly beneath the EP for heat spreading. Place a 3x3 grid of 0.3 mm thermal vias (0.2 mm drill) connecting the EP to an internal ground plane. Without this stitching, junction-to-ambient thermal resistance rises from approximately 40 C/W to over 80 C/W, risking thermal shutdown during sustained 25 MHz operation with all peripherals active.
Place 100 nF ceramic decoupling capacitors within 2 mm of each VDD pin (the PIC32MM0064GPL020T-I/ML has multiple VDD pins on different sides of the package). Add a single 10 uF bulk capacitor near the IC. Route ADC analog signals away from digital switching traces and use a ground pour on the top layer under the QFN. For ADC accuracy, use a separate analog ground pin if available, and connect AGND to DGND only at one point.
Do not omit the exposed pad (EP) solder connection - it is the primary thermal path AND ground connection for the MCU. Cold or missing solder joints here cause erratic behavior and ADC errors. PPS (Peripheral Pin Select) must be configured and locked after programming; an unlocked PPS allows accidental remapping in production firmware that breaks UART/SPI communication. Always include a JTAG/ICSP header or test pads for in-field firmware update capability.
