PIC32MM0064GPL028T-I/SO Visão geral
A PIC32MM is a 32-bit flash microcontroller that combines MIPS32 microAptiv core execution with low-power peripherals, sitting in the hierarchy of MCU -> 32-bit MCU -> ARM/MIPS architecture -> PIC32 family. The GPL sub-family emphasizes low pin count and ultra-low-power operation, with active current draw typically in the microampere range and integrated peripherals such as ADC, comparators, and configurable logic cells. This makes the family a practical bridge between 8-bit PIC microcontrollers and higher-performance PIC32MZ parts.
Key features of this device include a 25 MHz core clock, 64 KB of self-programmable Flash program memory, 8 KB SRAM, and 22 general-purpose I/O. Integrated peripherals include 12-bit ADC, configurable logic cells, and multiple serial interfaces (UART, SPI, I2C) for mixed-signal connectivity. The XLP design provides deep-sleep modes around 500 nA, retention RAM, and a power-aware peripheral scaling scheme.
The microAptiv core supports MIPS DSP extensions (with the GPL020/036/028 variants) and microMIPS instruction mode for higher code density, which is why parts like the PIC32MM are popular in cost-sensitive consumer and IoT designs. With 2.0 V to 3.6 V supply, on-chip voltage regulator, and multiple clock options, the device is robust for portable embedded applications.
Typical applications include IoT sensor nodes, low-power wireless-connected devices, wearables, motor control peripherals, and consumer electronics where sleep current dominates battery life. Industrial building automation, HVAC controls, and battery-powered instruments are also common end-markets. Designers should evaluate the 28-SOIC footprint for hand-rework prototypes versus the smaller QFN variants for high-volume products.

Aplicações típicas
PIC32MM0064GPL028T-I/SO é adequado para 7 aplicaçãos: IoT Sensor Node Controller, Wearable Health Device, Battery-Powered Consumer Remote Control, Industrial Building Automation Sensor, Low-Power Motor Control Peripheral, Smart Home Edge Controller, Portable Medical Monitoring Accessory.
IoT Sensor Node Controller
The PIC32MM0064GPL028T-I/SO is well suited to IoT sensor nodes because of its XLP deep-sleep currents near 500 nA and 2.0 V to 3.6 V supply that runs directly from a single lithium or 2x AA cell. With 64 KB Flash the device can host a small BLE/Zigbee stack plus application firmware. Placed as the central MCU with sensor I/O, ADC sampling, and UART link to a wireless co-processor; the low quiescent current means a coin-cell node can run for years. Trade-off vs higher-end MCUs: 25 MHz core is slow for heavy DSP.
Recomendado
Wearable Health Device
Wearable health devices benefit from the PIC32MM0064GPL028T-I/SO's 500 nA XLP sleep current, industrial temperature range, and 64 KB Flash that fits fitness firmware plus BLE stack. With 22 GPIO and integrated 12-bit ADC, the device can sample heart-rate, temperature, and motion sensors directly. Mounted as the system MCU on a coin-cell-powered wearable PCB; deep-sleep wake-up is via RTC or external interrupt. Trade-off: no integrated BLE radio - pair with an external module such as RN4870.
Recomendado
Battery-Powered Consumer Remote Control
The PIC32MM0064GPL028T-I/SO fits battery-powered remote controls because of its XLP sleep current and 2.0 V to 3.6 V supply compatible with 2x AAA cells. The 25 MHz core can drive IR modulation schemes, while 22 GPIO easily accommodates keypad scanning and LED indicators. Deployed as the central MCU with UART link to optional RF module; deep-sleep is gated by keypad interrupt to maximize battery life. Trade-off: limited PWM channels for advanced LED effects.
Recomendado
Industrial Building Automation Sensor
Industrial building automation sensors such as HVAC monitors, occupancy detectors, and energy meters benefit from the PIC32MM0064GPL028T-I/SO's industrial -40 C to +85 C rating, 64 KB Flash for application firmware, and 22 GPIO for multi-sensor integration. The 12-bit ADC and configurable logic cells handle analog sensor front-ends without external components. Used as the MCU in a wall-mounted sensor with 4-20 mA or RS-485 output; low quiescent current simplifies loop-powered designs.
Recomendado
Low-Power Motor Control Peripheral
Small motor control applications such as fans, pumps, and small BLDC drivers benefit from the PIC32MM0064GPL028T-I/SO's configurable logic cells, 12-bit ADC for back-EMF sensing, and 25 MHz core for commutation loops. The 22 GPIO provides enough PWM-capable pins for half-bridge or full-bridge control on small motors. Mounted as the main controller with gate-driver IC; XLP sleep enables standby power under 100 uW. Trade-off: not suited for high-RPM field-oriented control.
Recomendado
Smart Home Edge Controller
Smart home edge controllers benefit from the PIC32MM0064GPL028T-I/SO's 64 KB Flash that accommodates Zigbee or Thread application code, plus its industrial temperature range that survives attic and outdoor enclosure conditions. With UART, SPI, and I2C peripherals, the device interfaces to radios, sensors, and actuators. Used as a secondary MCU behind a wireless SoC; deep-sleep wake-up is via radio interrupt. Trade-off: not suited to host main Wi-Fi/BLE stacks.
Recomendado
Portable Medical Monitoring Accessory
Portable medical monitoring accessories such as glucose meter attachments or pulse-oximeter dongles benefit from the PIC32MM0064GPL028T-I/SO's low XLP current that meets the long battery-life requirements of medical peripherals, plus 64 KB Flash for algorithm code. The 12-bit ADC supports direct interface to analog sensor front-ends. Placed as the secondary MCU handling display and storage while a primary sensor ASIC handles the analog front-end; deep-sleep is used between readings.

Notas de projeto
The PIC32MM0064GPL028T-I/SO XLP deep-sleep current is around 500 nA with full RAM retention, so battery-life budgets must consider the wake-up interval and active-mode current. In active mode at 25 MHz with all peripherals on, current is roughly 4 mA, which dominates energy if the MCU is awake for long periods. For coin-cell designs, set wake-up intervals of 1-10 seconds and complete sensor sampling plus radio transmit within 10 ms. Estimated: 10 ms active at 4 mA every 5 seconds yields average current ~8 uA, allowing a 220 mAh CR2032 to last over 3 years.
Place decoupling capacitors as close as possible to the VDD pin (pin 17) on the 28-SOIC. Use a 100 nF ceramic on VDD plus a 10 uF bulk capacitor on the board supply. Keep the MCLR pull-up resistor (typically 10 kOhm) close to the MCLR pin (pin 1) to avoid spurious resets from noise. The PGED1/PGEC1 pins (RB0/RB1) should be brought out to a programming header for in-circuit serial programming (ICSP).
Do not assume the PIC32MM0064GPL028T-I/SO has 5 V tolerant I/O - all GPIO is 3.3 V only and over-voltage will damage the part. When migrating from PIC24/PIC32MX designs, confirm that any 5 V peripherals are level-shifted. Also note that microMIPS code density is ~30% better than MIPS mode but debugging tools must be configured correctly - failing to enable the proper compiler flags results in code-size warnings. Finally, the ADC reference voltage is limited to VDD; for ratiometric measurements supply a clean regulated rail.
