PIC32MX534F064LT-I/PF 概要
A PIC32MX microcontroller is a 32-bit MCU family from Microchip built on the MIPS32 M4K core architecture. It bridges the gap between 8/16-bit PIC microcontrollers and high-performance ARM Cortex-M parts by offering 32-bit computational throughput, large linear address space, and deterministic interrupt handling while preserving the MPLAB ecosystem (XC32 toolchain, Harmony framework, MPLAB X IDE). The "32MX" family is positioned for connected-embedded applications that need USB, CAN, Ethernet or Ethernet-ready peripherals along with moderate DSP performance.
Key features of the PIC32MX534F064LT-I/PF include 64 KB Flash program memory, 16 KB SRAM, an 8-channel 10-bit 1 Msps ADC, five 16-bit timers/capture/compare/PWM modules, two I2C and two SPI/I2S ports, two UARTs with IrDA support, full-speed USB 2.0 (Device/Host/OTG), CAN 2.0B, four-channel DMA, and an internal 8 MHz Fast RC oscillator with PLL. The "T" suffix denotes tape-and-reel packaging and the "-I/PF" suffix denotes industrial temperature grade (-40C to +85C) in the 100-pin TQFP package.
Architecturally, the M4K core provides a 5-stage pipeline, hardware multiply/divide, single-cycle MAC, and a tightly-coupled prefetch cache, which together with the bus-matrix DDR-style peripheral interconnect delivers deterministic throughput at 80 MHz. The peripheral set (USB + CAN + 4 DMA) is well-matched to industrial protocols and human-interface designs.
Typical applications include industrial control and HMI panels, USB peripherals and CAN node gateways, motor control and BLDC/PMSM drivers, embedded dataloggers, sensor hubs, and low-cost audio processing. The combination of USB device/host, CAN, and DMA makes it a flexible connectivity MCU for factory automation.
When designing with the PIC32MX534F064LT-I/PF, allocate decoupling capacitance (100 nF plus 4.7 uF bulk) within 5 mm of each power pin, route the 80 MHz system trace as a 50 ohm microstrip with reference-plane stitching, and bias the internal 8 MHz FRC plus PLL if precise USB or CAN timing is required - the USB module requires 48 MHz +/- 0.25% to meet USB 2.0 full-speed accuracy.

主な用途
PIC32MX534F064LT-I/PF の用途: 6 件s: Industrial Control and HMI Panels, USB Peripherals and Embedded Hosts, CAN Node Gateways and Automotive Body Modules, Motor Control and BLDC/PMSM Drivers, Sensor Hubs and Data Loggers, Low-Cost Audio Processing.
Industrial Control and HMI Panels
The PIC32MX534F064LT-I/PF fits industrial HMI panels because its 80 MHz MIPS M4K core delivers the throughput required to drive TFT LCDs via the 16-bit Parallel Master Port while running USB and CAN stacks concurrently. The 64 KB Flash accommodates a USB HID stack plus a graphics library, and the 16 KB SRAM is enough for double-buffered framebuffers up to 320x240 in 16-bit color. Industrial-grade -40C to +85C operation tolerates cabinet environments, and the on-chip CAN 2.0B interfaces directly to factory-floor networks without external transceivers beyond the standard ISO 11898 PHY. Place 100 nF + 4.7 uF decoupling within 5 mm of each VDD/VSS pair.
おすすめ
USB Peripherals and Embedded Hosts
The PIC32MX534F064LT-I/PF supports USB 2.0 Full-Speed in device, host, or OTG mode, making it ideal for USB peripherals such as data loggers, custom HID controllers, and embedded USB hosts reading mass storage. The on-chip USB transceiver requires only 15K pull-up on D+ for device mode, simplifying the BOM. At 80 MHz with 4 DMA channels, the CPU can sustain 12 Mbps USB traffic while handling background application logic. Designers should use Microchip's MPLAB Harmony USB stack which provides CDC, MSD, and HID class drivers ready for the XC32 toolchain.
おすすめ
CAN Node Gateways and Automotive Body Modules
The PIC32MX534F064LT-I/PF is well suited for CAN node gateways and automotive body modules because its CAN 2.0B module operates at bit rates up to 1 Mbps and the 4-channel DMA offloads message buffering from the CPU. With 64 KB Flash, designers can implement J1939 or CANopen protocol stacks. The industrial temperature grade handles under-dash environments, and the 100-pin TQFP provides enough GPIO for sensor aggregation. For higher temperature under-hood applications, the PIC32MX534F064H-I/PT (-40C to +125C) is pin-compatible. Pair with MCP2551 or TJA1050 CAN transceivers.
おすすめ
Motor Control and BLDC/PMSM Drivers
For sensorless BLDC or PMSM motor control, the PIC32MX534F064LT-I/PF provides 5 16-bit timers with PWM output compare, which generate the 3-phase complementary PWM with dead-band insertion needed for 6-step or FOC commutation. The 10-bit 1 Msps ADC samples back-EMF or phase currents fast enough for low-RPM torque control. With DMA offloading ADC conversion, the CPU stays free for control-loop math at 80 MHz (single-cycle MAC). Pin-compatible higher-memory variants like PIC32MX460F512L-80I/PT support richer control firmware.
おすすめ
Sensor Hubs and Data Loggers
The PIC32MX534F064LT-I/PF serves as a sensor hub or data logger because its 16-channel 10-bit ADC, 2 I2C ports, and 2 SPI ports can aggregate data from multiple sensors while USB streams the data to a host PC. The 4 DMA channels move ADC samples and SPI/I2C transactions without CPU intervention, leaving cycles for filtering or compression. With 16 KB SRAM, the part can buffer several seconds of high-rate sensor data before flushing to USB or external Flash. Industrial temperature grade supports outdoor sensor installations.
おすすめ
Low-Cost Audio Processing
The PIC32MX534F064LT-I/PF can perform low-cost audio processing such as sample-rate conversion, simple effects, or USB audio class (USB Audio 1.0) streaming thanks to its 2 I2S ports and DSP-friendly MIPS M4K core (single-cycle MAC). At 80 MHz, the CPU can process 48 ksps stereo audio with headroom for filters and mixing. The 2 UARTs support MIDI input/output, making the part suitable for MIDI controllers or audio interfaces. Use MPLAB Harmony audio frameworks to simplify USB Audio Class enumeration.

設計ノート
Place a 100 nF ceramic decoupling capacitor as close as possible (within 5 mm trace length) to every VDD/VSS pair on the PIC32MX534F064LT-I/PF, plus a single 4.7 uF bulk capacitor at the package power entry. The internal 1.8V core LDO requires clean VDD - noisy supply degrades USB jitter and ADC accuracy. For analog-heavy designs (ADC, VREF+), power the analog pins AVDD/AVSS from a separate filtered LDO rail (e.g., MCP1700-33) to keep digital switching noise out of the ADC reference. The VUSB pin (pin 52) requires a local 100 nF + 4.7 uF pair for the USB transceiver regulator.
Do not exceed 3.6 V on any VDD pin - the PIC32MX534F064LT-I/PF core is rated 2.3-3.6V. USB 5V VBUS must be conditioned through a USB-compliant power switch (such as MCP1640 or MIC2026) before reaching the VBUS detect pin. The MCLR pin (pin 100) requires a 10 kohm pull-up to VDD and a 100 nF cap to ground for clean reset; leaving MCLR floating causes intermittent failures. Also, the JTAG pins (TMS/TCK/TDI/TDO) must be left floating or pulled high when not in use - do not tie them to ground.
Route the 80 MHz system clock traces as 50 ohm microstrip with continuous reference plane underneath; vias in the reference plane degrade signal integrity. Keep the USB D+/D- traces matched within 2 mm and routed over a continuous ground plane - microchip's AN26.2 layout guide documents the 90 ohm differential requirement. Place the 8 MHz or 12 MHz crystal within 5 mm of OSC1/OSC2 (pins 24-25) with a grounded guard ring to prevent noise coupling into the PLL. Estimated trace length budget: keep all high-speed traces under 25 mm if possible.
コンプライアンス情報
