PIC32MM0064GPL028T-I/SS Overview
Background: A microcontroller (MCU) is a single-chip computer integrating processor core, memory (Flash for program, SRAM for data), and peripherals (ADC, timers, communication interfaces) into one IC. The PIC32MM GPL family is positioned at the low-cost, ultra-low-power tier of Microchip's 32-bit portfolio, designed for battery-powered and space-constrained designs. It uses the microMIPS instruction set, allowing denser code than standard MIPS32 while retaining full compatibility with the MIPS32 architecture for the same C toolchain.
Key features include up to 79 CoreMark performance at 25MHz, 64KB self-programmable Flash with 20,000 erase/write cycles and 20-year retention, 8KB SRAM, 4 DMA channels, a 12-bit 1MSPS ADC, multiple comparators, and configurable logic cells. The device operates from 2.0V to 3.6V with five low-power modes and active current consumption under 1 mA per MHz.
Technical depth: The microAptiv core integrates DSP extensions and a hardware multiply/divide unit, while the peripheral set supports I2C, SPI, UART, and 16-bit PWM. The Fail-Safe Clock Monitor (FSCM) detects primary oscillator failure and switches to an internal backup source, making the part suitable for industrial and safety-relevant control loops.
Typical applications include low-power IoT sensor nodes, consumer wearables, battery-powered instrumentation, motor control peripherals, and small home appliances. Designers use the PIC32MM GPL when deterministic low-power operation and a tiny footprint matter more than raw CPU throughput.
Design consideration: For drop-in PCB reuse across the PIC32MM GPL family, the PIC32MM0064GPL028T-I/SS shares pin compatibility with PIC24 and dsPIC33 devices at the 28-pin SSOP level, easing migration. Use MPLAB X IDE and XC32 compiler for code development; ensure decoupling capacitors are placed within 5mm of VDD/AVDD pins.

Typical Applications
PIC32MM0064GPL028T-I/SS is suitable for 6 applications: Battery-Powered IoT Sensor Node, Consumer Wearable Device, Home Appliance Control Board, Industrial Sensor Transmitter, Remote Control / Wireless HID, Low-Cost Data Logger.
Battery-Powered IoT Sensor Node
The PIC32MM0064GPL028T-I/SS suits ultra-low-power IoT sensor nodes with its 500 nA sleep current, 2.0V-3.6V supply, and 64KB Flash. The 25MHz microAptiv core wakes periodically to read sensors via the 12-bit 1MSPS ADC, processes data, and transmits via SPI/UART. With DMA support, the core stays asleep while peripherals move data, extending battery life to years on a single coin cell.
Recommended
Consumer Wearable Device
Consumer wearables require low-power operation, small PCB footprint, and enough Flash for BLE stack and sensor-fusion algorithms. The PIC32MM0064GPL028T-I/SS in 28-SSOP provides 64KB Flash (sufficient for Bluetooth Low Energy profiles and simple RTOS tasks) while drawing under 1 mA active per MHz. Designers typically pair it with an external accelerometer and BLE module via SPI.
Recommended
Home Appliance Control Board
Small home appliances like coffee makers, blenders, and air purifiers need reliable 32-bit performance and low cost. The PIC32MM0064GPL028T-I/SS handles user I/O (buttons, displays), motor PWM, and sensor reads with its 16-bit PWM and CLC blocks. The Fail-Safe Clock Monitor ensures continued operation if the primary oscillator fails, important for unattended appliance safety.
Recommended
Industrial Sensor Transmitter
Industrial 4-20mA sensor transmitters need deterministic 32-bit processing, robust peripherals, and wide operating temperature. The PIC32MM0064GPL028T-I/SS operates from -40C to +85C and runs the 25MHz microAptiv core for linearization and HART protocol modulation. The 12-bit ADC achieves 1MSPS for fast thermocouple or pressure sensor reads with hardware DMA offload.
Recommended
Remote Control / Wireless HID
Wireless remote controls need long battery life, low latency wake, and compact form factor. The PIC32MM0064GPL028T-I/SS wakes from 500 nA sleep on a GPIO interrupt, processes button matrix input via CLC and timers, and sends IR or RF commands via SPI/ UART. The 64KB Flash supports OEM firmware and wireless stack updates.
Recommended
Low-Cost Data Logger
Portable data loggers for environmental monitoring use the PIC32MM0064GPL028T-I/SS to sample sensors periodically and store to external EEPROM or SD card. The 64KB Flash accommodates logging firmware and calibration tables, while 8KB RAM supports circular buffers between flush events. DMA-driven ADC-to-memory operation keeps the CPU idle, saving power.

Key Differentiators
- Same SSOP-28 pinout across Flash densities (vs PIC32MM0032GPL028T-I/SS)
- 500 nA sleep current for battery designs (vs PIC32MM0016GPL028T-I/SS)
- Pin-compatible with PIC24FJ and dsPIC33 SSOP-28 (vs PIC24FJ64GA702-I/SS)
Design Notes
Estimated: at 3.3V VDD and 25MHz active CPU draw of approximately 8 mA, the PIC32MM0064GPL028T-I/SS consumes about 26 mW. In sleep mode the part draws 500 nA, enabling multi-year battery life when duty-cycled at 0.1% active time. Use the deep-sleep mode with RTCC wake for lowest power, and gate peripheral clocks via PMD registers to reduce active current.
Place 100nF decoupling capacitors within 5mm of each VDD/AVDD pin, with a bulk 10uF tantalum or ceramic at the regulator output. Keep analog and digital ground planes separated and join at a single point near the MCU. Use wide traces for VDD and VSS to handle the 25MHz peak current transients without IR drop.
Do not exceed 3.6V on any pin including MCLR; use a 10kohm pull-up and TVS diode on MCLR for ESD protection. Configure unused pins as digital outputs (not floating) to minimize shoot-through current. The 12-bit ADC requires a 1us acquisition time - shorter times cause inaccurate conversions on high-impedance sources.
Compliance Information
RoHS and REACH compliant per Microchip product page. Lead-free reflow compatible. Not AEC-Q100 qualified - this is a commercial/industrial grade part. Industrial temperature range -40C to +85C.
