PIC32MM0064GPM064T-I/MR 개요
A 32-bit microcontroller (MCU) is an embedded processor that integrates CPU core, memory, and peripherals on a single die; the MIPS32 microAptiv UC is a low-power synthesizable core featuring microMIPS compressed instruction support, hardware multiply-accumulate, and zero overhead loops. The PIC32MM family sits within the broader taxonomy: microcontroller -> 32-bit MCU -> MIPS-based MCU -> low-power MCU -> USB-capable MCU, designed for cost-sensitive battery-powered designs requiring deterministic real-time response.
Key features include 64 KB ECC Flash, 16 KB SRAM, up to 25 MHz operation, integrated USB 2.0 FS device/host/OTG controller with dedicated DMA, 12-bit 200 ksps ADC, multiple UART/SPI/I2C peripherals, and a 16-bit Parallel Master Port. The 64-QFN exposed pad provides a thermal resistance of approximately 22 C/W, allowing sustained operation at 25 MHz without active cooling.
Architecturally, the device couples the microAptiv UC pipeline with separate bus paths for instruction and data, accelerating interrupt response to 7 cycles. Dedicated DMA channels service USB and ADC peripherals, offloading the core to sustain deterministic USB packet timing even with ECC-enabled Flash reads. The integrated low-power voltage regulator supports run, idle, sleep, and deep-sleep modes with sub-1 µA deep-sleep current.
Typical applications include USB peripherals (HID, CDC, vendor-class), low-power sensor hubs with USB enumeration, fitness wearables, portable medical monitoring, and consumer IoT nodes requiring an attached USB interface. The USB OTG capability also enables it to act as a host for simple peripherals such as keyboards or mass-storage devices.
When designing with this MCU, allocate the exposed pad to a continuous ground pour with at least 16 thermal vias for 25 MHz continuous operation. Decouple VDD/VBUS with 100 nF X7R ceramic capacitors placed within 2 mm of each supply pin. Reserve the D+/D- pair for a 90-ohm differential routing per USB 2.0 spec.

일반적인 애플리케이션
PIC32MM0064GPM064T-I/MR 적합 용도: 6 애플리케이션s: USB HID / CDC Peripherals, Battery-Powered Sensor Hubs, Industrial Control with USB Logging, Portable Medical Monitoring, USB Host Peripherals (HID/Hub), Consumer IoT with USB Diagnostics.
USB HID / CDC Peripherals
The PIC32MM0064GPM064T-I/MR is purpose-built for USB Human Interface Devices and CDC-class virtual COM ports thanks to its integrated USB 2.0 Full-Speed controller with dedicated DMA. The 25 MHz microAptiv UC core delivers 79 CoreMark, more than sufficient for HID report handling, CDC line-codec processing, and a USB-suspended wake path. The 64 KB ECC Flash fits USB stacks such as Microchip Harmony USB plus a small application task, while 16 KB SRAM is ample for HID report buffers and endpoint descriptors. Deep-sleep current under 1 µA permits battery-powered HID devices that resume on USB bus activity. Engineers gain a true single-chip USB peripheral MCU with no external PHY, reducing BOM cost versus discrete USB interface chips.

Battery-Powered Sensor Hubs
For wearable and IoT sensor hubs, the PIC32MM0064GPM064T-I/MR combines 64 KB ECC Flash, 16 KB SRAM, sub-1 µA deep-sleep current, and an integrated USB OTG port for tethered data offload. The microAptiv UC core's microMIPS compressed instructions reduce code density, fitting richer sensor-fusion algorithms into 64 KB. The 12-bit 200 ksps ADC handles temperature, battery voltage, and external sensor channels simultaneously while DMA offload keeps the CPU in sleep. USB OTG enables the same node to enumerate as a device for charging or as a host to attach a mass-storage card. The 64-QFN exposed pad allows sustained 25 MHz operation with a small footprint suitable for wristbands and patches.
추천
Industrial Control with USB Logging
The PIC32MM0064GPM064T-I/MR suits industrial USB-logging applications such as configuration tools, RS-485 bridges, and field-service data dumpers. Its industrial -I temperature grade (-40C to +85C) survives factory-floor environments, while the USB Full-Speed port provides a service interface for log retrieval and firmware updates. The 64 KB Flash and 16 KB SRAM are sufficient for a small RTOS or bare-metal stack handling logging, USB CDC streaming, and one or two UART peripherals. The 64-QFN's 22 C/W thermal resistance allows 25 MHz continuous operation in sealed enclosures without active cooling. ECC Flash protection reduces the risk of bit-flips disrupting long-term data retention in fielded equipment.
추천
Portable Medical Monitoring
Although not AEC-Q100 qualified, the PIC32MM0064GPM064T-I/MR is suitable for non-automotive portable medical monitors such as USB-tethered pulse oximeters, Bluetooth-class dongles, and consumer health devices. Its USB Full-Speed port provides a regulated 5 V power path for the analog front-end and a data path for streaming physiological data to a host PC. The microAptiv UC core's deterministic interrupt latency suits time-critical waveform sampling, while the 12-bit ADC and DMA offload support simultaneous multi-channel acquisition. Deep-sleep sub-1 µA current extends battery life between charge cycles in patient-worn devices. The lead-free 64-QFN package is compatible with medical PCB reflow processes.

USB Host Peripherals (HID/Hub)
In USB host applications, the PIC32MM0064GPM064T-I/MR can enumerate keyboards, mice, or simple mass-storage devices via its USB OTG controller. The microAptiv UC core's microMIPS compressed code path allows USB host stack plus HID parser to fit within 64 KB Flash, while 16 KB RAM supports descriptor buffers. The device requires an external 48 MHz clock source in host mode, generated from a crystal or external oscillator. Engineers can implement keyboard/mouse-to-UART bridges, simple KVM switches, or factory-floor barcode-reader aggregators using the same PCB footprint as the device-only firmware. The 64-QFN package exposes the USB D+/D- pins on dedicated ports for clean 90-ohm differential routing.
추천
Consumer IoT with USB Diagnostics
Consumer IoT products benefit from the PIC32MM0064GPM064T-I/MR's USB diagnostics channel, which lets installers and service technicians interface with fielded devices without dedicated UART pins or debug headers. The microAptiv UC core delivers 79 CoreMark at 25 MHz, ample for simple Wi-Fi/BLE co-processor orchestration, sensor polling, and USB CDC command parsing. The 12-bit ADC supports battery monitoring and analog sensor reads, while DMA offload frees the core for command processing. Sub-1 µA deep-sleep current preserves coin-cell or Li-ion battery life when the host is unplugged. The 64-QFN 9x9 mm package fits compact IoT enclosures and shares the same footprint as the higher-memory 256 KB and 512 KB family members for scalable product tiers.

- USB OTG with dedicated DMA, no external PHY required (vs PIC32MM0064GPL036T-I/MV)

설계 노트
The 64-QFN exposed pad MUST be soldered to a continuous ground pour with at least 16 thermal vias (0.3 mm drill, 0.6 mm pitch) for reliable operation at 25 MHz continuous load. Estimated: with 4-layer FR4 (1 oz outer copper) and 16 vias, the thermal resistance theta_JA is approximately 22 C/W. Without the thermal pad connection, junction temperature can rise 30% above expected, causing thermal shutdown during USB enumeration peak current.
Route the USB D+ and D- lines as a 90-ohm differential pair with matched length (within 150 mil), keeping them on the same layer and away from switching regulators or clock traces. Place the USB-series ferrite or common-mode choke within 5 mm of the MCU. Add 15 kV ESD protection (e.g., USBLC6-2SC6) at the connector. Decouple each VDD pin with 100 nF X7R ceramic within 2 mm and add a bulk 4.7 µF tantalum within 10 mm of the IC.
The PIC32MM0064GPM064T-I/MR supports three operating modes: Run (typical 7 mA at 25 MHz), Idle (3 mA), and Deep Sleep (sub-1 µA). For USB bus-powered designs, ensure VBUS-derived 3.3 V regulator provides at least 100 mA peak headroom for enumeration current spikes. Disable unused peripherals in the peripheral module disable (PMD) registers to reduce active current by up to 30%. Estimated: enabling both ADC and USB simultaneously adds approximately 2 mA.
Do not exceed 3.6 V on VDD - the PIC32MM GPM family is not 5 V tolerant. When migrating from PIC32MX, note that the microAptiv UC interrupt vector table is different; the family reference manual DS60001387 must be reviewed for peripheral register compatibility. The ECC Flash feature requires ECC to be enabled via configuration bits before any code execution, or unpredictable behavior may occur on bit-flipped reads.
For USB Full-Speed operation at 12 Mbps, the rise/fall time of D+/D- must be between 4 and 20 ns per USB 2.0 spec. Series resistors on D+/D- (typically 27 ohms) are required if the device is on a non-impedance-controlled board. The internal full-speed pull-up on D+ is selectable via software; do not add an external 1.5 k pull-up or bus conflicts will occur.
