PIC32MM0064GPM064T-I/PT Overview
A 32-bit microcontroller (MCU) is a single-chip computer that integrates a 32-bit CPU core, flash program memory, SRAM data memory, and a rich set of peripherals including timers, communication interfaces, and analog blocks. Within the semiconductor taxonomy, a microcontroller falls under microcontrollers, which sit within integrated circuits, and ultimately within semiconductors. The PIC32MM GPM family specifically targets cost-sensitive, low-power applications by extending Microchip's PIC32 portfolio with USB and hardware ECC, while preserving upward migration paths to higher-performance PIC32 families.
Key features include a 25 MHz core speed with hardware multiply/divide, 79 CoreMark performance, deep-sleep current as low as 650 nA with retention, a 10-bit 200 ksps ADC and a 12-bit ADC for precision analog sampling, multiple communication peripherals including USB, I2C, SPI, and UART, and a wide 2 V to 3.6 V operating voltage range suitable for single-cell Li-ion or 2x AA battery systems. The integrated ECC on Flash and RAM improves reliability in electrically noisy environments.
Technically, the device uses the MIPS32 microAptiv core with microMIPS instruction support for improved code density, a dual-bank flash architecture for safe in-field updates, and a peripheral pin-select (PPS) system that remaps digital functions to any I/O pin, simplifying PCB routing. The on-chip USB 2.0 Full-Speed device controller enables plug-and-play tethered or battery-powered USB applications without an external PHY.
Typical applications include battery-powered IoT sensor nodes, wearable fitness/health devices, low-power USB peripherals such as HID and CDC class devices, remote controls and home automation, portable medical instruments, and consumer products requiring low standby power with reliable flash integrity.
When designing with this part, plan the PCB layout for the 0.5 mm pitch TQFP-64 footprint and route the USB DP/DM lines as a 90 ohm differential pair. Use the PPS system to map peripherals to convenient pins and use deep-sleep modes aggressively to achieve the advertised sub-microamp standby currents.

Typical Applications
PIC32MM0064GPM064T-I/PT is suitable for 6 applications: Battery-Powered IoT Sensor Nodes, Wearable Fitness and Health Devices, Low-Power USB Peripherals (HID / CDC), Remote Controls and Home Automation, Portable Medical Instruments, Industrial Sensing and Data Loggers.
Battery-Powered IoT Sensor Nodes
The PIC32MM0064GPM064T-I/PT is well-suited to battery-powered IoT sensor nodes because it draws as little as 650 nA in deep-sleep with RAM retention, while its 64 KB ECC flash and 16 KB SRAM comfortably hold Zigbee or LoRa protocol stacks alongside application code. The 2 V to 3.6 V supply range allows direct connection to single-cell Li-ion or 2x AA batteries without an external LDO. Designers typically use the 12-bit ADC for sensor sampling and wake the core from sleep via a PPS-mapped interrupt to take measurements, then return to sleep to maximize battery life across multi-year deployments.
Recommended
Wearable Fitness and Health Devices
For wearable fitness and health devices, the PIC32MM0064GPM064T-I/PT delivers the right combination of small TQFP-64 footprint, 25 MHz processing for sensor fusion, and extreme low deep-sleep current to extend coin-cell runtime. Its 12-bit ADC captures high-fidelity biometric signals such as heart rate and SpO2 photodiode currents, while the 10-bit ADC handles secondary channels like battery monitoring. The USB Full-Speed device controller allows fast charging port enumeration, and the ECC flash protects against the bit-flips that wearable enclosures often induce during flexing.
Recommended
Low-Power USB Peripherals (HID / CDC)
The PIC32MM0064GPM064T-I/PT integrates a USB 2.0 Full-Speed device controller without an external PHY, making it ideal for low-power USB peripherals such as HID keyboards, mice, CDC virtual COM ports, and vendor-class data loggers. Its 25 MHz MIPS32 microAptiv core handles USB stacks plus application logic simultaneously, while the deep-sleep mode keeps suspend current below USB 2.0 suspend requirements. Engineers route the USB DP/DM traces as a 90 ohm differential pair directly to the dedicated package pins, simplifying compliance.
Recommended
Remote Controls and Home Automation
In remote controls and home automation hubs, the PIC32MM0064GPM064T-I/PT excels because of its 650 nA sleep and integrated USB for firmware update over a standard micro-USB port. The PPS peripheral pin-select system allows RF modules and key-scan matrices to be mapped onto convenient I/O without redesign. The 64 KB ECC flash holds wireless protocol stacks such as Thread or proprietary 2.4 GHz, while the 12-bit ADC can read battery voltage and light sensors for context-aware automation.
Recommended
Portable Medical Instruments
Portable medical instruments such as glucose meters, pulse oximeters, and handheld diagnostic tools benefit from the PIC32MM0064GPM064T-I/PT's combination of ECC flash (important for medical-grade reliability), low deep-sleep current, and integrated USB. The 12-bit ADC captures accurate biosignals, while the 25 MHz core runs filtering and display updates without breaking a sweat. The wide 2 V to 3.6 V supply lets designers use 2x AA or Li-primary cells directly, eliminating an LDO and improving overall efficiency.
Recommended
Industrial Sensing and Data Loggers
For industrial sensing and data loggers, the PIC32MM0064GPM064T-I/PT provides ECC-protected flash that guards against bit-flips in electrically noisy factory environments. Its 12-bit ADC handles multi-channel analog sensing, and the integrated USB supports tethered configuration and data download. The 64-pin TQFP package exposes enough GPIO to interface with multiple sensor types simultaneously, while the 25 MHz MIPS32 microAptiv core is sufficient to perform local filtering, thresholding, and statistics before transmission.

Key Differentiators
- Hardware ECC on Flash and RAM for higher reliability (vs PIC32MX470F512L-I/PT)
- Ultra-low 650 nA deep-sleep with retention (vs PIC32MK1024MCM064-I/PT)
- Cost-effective 25 MHz MIPS32 core for low-power designs (vs PIC32MK1024MCF064-E/PT)
Design Notes
Estimated: At VDD = 3.3 V and active current draw of approximately 5 mA at 25 MHz, power dissipation is ~16.5 mW. In deep-sleep at 650 nA, dissipation drops to ~2.1 uW with RAM retention. Place a 100 nF decoupling capacitor as close as possible to each VDD/VSS pair, plus a single 4.7 uF bulk capacitor near the package. Use the PMD register to disable unused peripherals and enter deep-sleep aggressively to achieve the 650 nA figure.
The TQFP-64 (10x10 mm) package has a 0.5 mm pin pitch which requires careful PCB layout. Route USB DP/DM as a 90 ohm differential pair with continuous ground reference underneath. Keep the crystal traces short and symmetric, surrounded by a ground guard ring to reduce EMI. Connect all VSS pins to a single ground plane and place bulk capacitors close to the supply pins. Avoid running high-speed signals over the ground plane split between analog and digital sections.
Do not skip the VUSB decoupling capacitor; USB functionality requires a 1 uF capacitor on the VUSB pin. Do not leave MCLR floating - tie it to VDD through a 10 kohm pull-up for normal operation. When using PPS, remember that the input and output functions are mapped independently and the same pin cannot host both at once without configuration conflicts. Finally, ensure flash programming voltage is correct before attempting to write ECC-protected regions.
For USB Full-Speed signals, target 90 ohm differential impedance with traces no longer than ~50 mm on the carrier board. Add common-mode chokes if the design must pass CISPR 22/EN 55022 Class B radiated emissions tests. Place a 47 ohm series resistor on each USB line close to the connector to dampen reflections, and route the differential pair over a continuous ground plane without crossing plane splits.
Compliance Information
RoHS and REACH compliant per Microchip product page; lead-free TQFP package. Industrial temperature grade -40C to +85C; not AEC-Q100 qualified - choose PIC32MK series for automotive.
