PIC32MX470F512LT-V/PF 概要
A microcontroller (MCU) is a single-chip computer containing a processor core, memory, and programmable peripherals. PIC32MX devices sit in the taxonomy: microcontroller -> embedded MCU -> 32-bit MCU -> MIPS M4K architecture -> Microchip PIC32 family. The 32-bit M4K core delivers up to 120 MHz / 150 DMIPS at the family level, with this specific -V variant rated for 80 MHz operation. This enables efficient execution of RTOS, USB stacks, and graphics libraries.
Key features include 512KB on-chip Flash (512K x 8), 128KB SRAM, USB 2.0 Full-Speed OTG, 4-channel DMA, two I2C, two SPI/I2S, five UART, two analog comparators, 28-channel 10-bit ADC at 1 Msps, parallel master port (PMP) for external bus/display, and 5 16-bit timers. The 100-pin TQFP package (14x14 mm) gives ample GPIO (78+ I/O) for human-machine interface, motor control, and connectivity applications.
The device uses the Harvard architecture with separate 32-bit instruction and 8/16/32-bit data paths, plus hardware multiply/divide and DSP extensions. A 1.5-cycle interrupt latency and vectored interrupt controller support deterministic real-time response, while the PMP and DMA enable display and high-throughput data movement offloading the core.
Typical applications include industrial control panels, USB device/host peripherals, CAN-bridge gateways, low-cost graphics HMI, multi-protocol sensor hubs, and consumer appliances needing 32-bit performance without stepping up to Cortex-M3/M4 parts. The wide peripheral set reduces external chip count, simplifying BOM.
Design consideration: the -V temperature grade (V denotes -40C to +105C) means this part is qualified for industrial-thermal-range applications but NOT AEC-Q100 automotive; choose PIC32MX470F512LT-120I/PF or family AEC-Q100 qualified siblings for harsh environments.

主な用途
PIC32MX470F512LT-V/PF の用途: 7 件s: USB Device/Host Peripherals, Industrial Control HMI Panels, Multi-Protocol Sensor Hubs, Audio Processing and Synthesis, Motor Control and BLDC Drives, Point-of-Sale and Ticketing Terminals, Medical Data Acquisition Devices.
USB Device/Host Peripherals
The PIC32MX470F512LT-V/PF integrates USB 2.0 Full-Speed OTG with on-chip transceiver and 4 KB of dedicated endpoint RAM, enabling CDC, HID, MSD, and vendor-class device implementations without external PHY. Its 80 MHz / 100 DMIPS M4K core comfortably runs USB stacks plus application logic. Place 100 nF decoupling on every VDD pin and route D+/D- as a 90 ohm differential pair; this part fits USB HID input devices, USB-to-UART bridges, and custom HID sensors. Compared to STM32F0, it requires no external 1.5 kohm pull-up for device-mode detection - the OTG controller handles pull-up internally.
おすすめ
Industrial Control HMI Panels
With 28 ADC channels, two analog comparators, five UART, and a Parallel Master Port (PMP) for graphic LCDs, the PIC32MX470F512LT-V/PF directly drives mono STN/TFT panels up to QVGA without an external graphics controller. The 100-TQFP exposes enough I/O for keypad scanning, multiple PWM outputs, and encoder feedback. The -V grade operates to +105C, suitable for cabinet interiors. Pair it with a 4-wire resistive touch controller via SPI and a CAN transceiver for industrial networking; the 4-channel DMA offloads repetitive peripheral transfers.
おすすめ
Multi-Protocol Sensor Hubs
The PIC32MX470F512LT-V/PF's 2 I2C, 2 SPI/I2S, 5 UART, and 28 ADC channels simultaneously aggregate sensor data from I2C sensors, SPI ADCs, UART GPS modules, and analog transducers. The 80 MHz core plus 4-channel DMA enables sub-millisecond sensor fusion loops. Its 128 KB SRAM buffers data while the M4K DSP extensions accelerate FIR filters. Choose this for smart thermostats, environment monitors, and industrial data loggers needing multiple protocol bridges; the low BOM footprint of a single TQFP plus passives simplifies FCC/CE certification.
おすすめ
Audio Processing and Synthesis
The PIC32MX470F512LT-V/PF supports I2S protocol on two of its SPI peripherals, enabling stereo audio I/O at up to 48 kHz / 16-bit with DMA-driven sample streams. The M4K DSP extensions perform real-time mixing, equalization, and basic effects. Its 512 KB Flash holds uncompressed audio assets for low-latency playback. Use it for digital mixers, audio effects pedals, and intercom systems. The 128 KB SRAM is sufficient for multi-channel buffers; for higher sample rates, add external SRAM via PMP. Decouple VDDCAP with 10 uF ceramic for low-noise analog performance.
おすすめ
Motor Control and BLDC Drives
With five 16-bit timers and PWM outputs, plus high-speed ADC sampling triggered by PWM edges, the PIC32MX470F512LT-V/PF implements field-oriented control (FOC) of 3-phase brushless DC motors up to several kW. The 80 MHz core executes Park/Clarke transforms within microseconds. The -40C to +105C range suits industrial drives. Add three-phase gate drivers like the MCP8024; the 470's DMA moves ADC samples directly to memory, freeing the core for control loops. Note that the 100-TQFP provides adequate ground pins for noise-sensitive analog feedback.
おすすめ
Point-of-Sale and Ticketing Terminals
The PIC32MX470F512LT-V/PF's USB OTG, dual SPI/I2S, 28 ADC channels, and PMP external bus interface make it suitable for compact POS terminals: magnetic-stripe reader, thermal printer head, and keypad matrix integrate cleanly. The 512 KB Flash stores font tables and transaction logic; the 80 MHz performance runs custom encryption and LCD update within budget. Its wide 100-pin TQFP eases hand rework for service technicians. Add a real-time clock like MCP79410 via I2C; the 470's DMA moves thermal-print buffer streams at full speed.
おすすめ
Medical Data Acquisition Devices
While not AEC-Q100, the PIC32MX470F512LT-V/PF is well-suited to non-life-support medical peripherals such as pulse oximeters, blood-pressure cuffs, and digital stethoscopes. Its 10-bit 1 Msps ADC captures bioelectric signals; dual SPI/I2S interfaces stream to audio codecs; USB OTG provides tethered PC connectivity. The 128 KB SRAM buffers ECG samples. The -V +105C grade handles warm enclosure environments. For higher ADC resolution, pair with an external 16-bit sigma-delta ADC via SPI. Note: IEC 60601 compliance must be qualified at the system level, not at the MCU.

設計ノート
Decouple every VDD/VDDCAP pin with 100 nF X7R ceramic capacitors placed within 3 mm of the pin, plus a bulk 10 uF tantalum or ceramic near the regulator. Tie all VSS pins to a low-impedance ground plane - the 100-TQFP has multiple GND pins that must all be connected. USB applications must supply VUSB3V3 with a clean 3.3V rail and add a 100 nF + 4.7 uF capacitor pair; failure to bypass USB supply couples noise into D+/D- lines causing USB enumeration failures.
Route the 8 MHz primary oscillator traces within 1 cm of the OSCI/OSCO pins, guard-band them with a ground keep-out zone, and keep digital switching signals away from the crystal area. Maintain a continuous ground plane under the IC with no splits - the analog ADC and USB subsystems both depend on a low-noise ground reference. The 100-TQFP's exposed die-attach paddle (not present on this TQFP variant; only on QFN parts) - thermal dissipation relies on copper pours stitched with vias beneath the body.
Do not assume default PPS mapping - the PIC32MX4 peripheral pin select (PPS) registers must be configured at startup to assign functions to physical pins; the bootloader does not set sensible defaults. Do not exceed 3.6 V on any digital I/O pin; 5V tolerance is limited to specific pins only - consult the electrical characteristics table. Also, when using the parallel master port (PMP), set PMAEN bits before PMPMODE to avoid spurious bus activity that can disturb the LCD panel.
At full CPU load (80 MHz) with all peripherals active, the device draws approximately 60-80 mA from VDD, dissipating around 200-290 mW. The 100-TQFP theta_JA is ~50 C/W, yielding junction temperatures within the -40C to +105C operating range under normal airflow. For sealed enclosures above +60C ambient, derate CPU frequency or add copper-flood heatsinking around the TQFP body to maintain margin.
