PIC32MX534F064LT-V/PF Visão geral
A PIC32MX microcontroller is a MIPS-based 32-bit MCU that bridges 8/16-bit PIC legacy code to full 32-bit performance at low power. The MIPS32 M4K core executes most instructions in a single cycle, giving 1.56 DMIPS/MHz and deterministic interrupt latency. The PIC32MX5xx family sits in Microchip's mid-tier MCU hierarchy: PIC10/12/16/18 (8-bit) -> PIC24/dsPIC33 (16-bit) -> PIC32MX (32-bit) -> PIC32MZ/32MK (32-bit high performance) -> 32-bit ARM Cortex-M0+/M4/M7 (SAM). PIC32MX parts share a unified MPLAB X toolchain, Harmony framework, and peripheral library across the family.
Key features of the PIC32MX534F064LT-V/PF include: 80 MHz CPU clock, 64 KB Flash with live update support, 16 KB SRAM, USB 2.0 full-speed OTG, CAN 2.0B, 10-bit 1 Msps ADC, four DMA channels, five 16-bit timers, two I2C, two SPI, and five UART. The integrated 8 MHz internal RC and 4x PLL allow flexible clocking. The 100-pin TQFP exposes 85 GPIO, ideal for HMI, motor-control and connectivity gateways.
Typical applications are automotive body and infotainment modules, USB peripherals (HID, CDC, mass storage), industrial sensors with CAN-bus aggregation, and consumer audio accessories. Designers choose this part when they need a wide-temperature automotive-grade MCU with on-chip USB OTG and CAN without an external transceiver for low-speed CAN. The V/PF package is the 100-pin TQFP - for compact designs, the 64-pin TQFP (PT) variant PIC32MX534F064LT-V/PT provides the same silicon in a smaller footprint.

Aplicações típicas
PIC32MX534F064LT-V/PF é adequado para 6 aplicaçãos: Automotive Body Control Modules, USB HID / CDC Peripherals, Industrial CAN Sensor Hubs, Consumer Audio Accessories, HMI Touchscreen Controllers, Data Acquisition with USB Streaming.
Automotive Body Control Modules
The PIC32MX534F064LT-V/PF's -40C to +105C V-grade temperature rating makes it well suited for automotive body control modules that aggregate switch, lighting, and CAN bus inputs. With on-chip CAN 2.0B, the MCU eliminates the need for an external CAN controller IC, reducing BOM cost and PCB area. The 64 KB Flash accommodates AUTOSAR-lite or OSEK RTOS kernels plus the CAN/LIN stack, while the 16 KB SRAM double-buffers CAN message queues. Engineers typically place the PIC32MX534F064LT-V/PF between a 12V-to-3.3V regulator and the CAN bus transceiver, running the CANopen or J1939 stack at 500 kbps on a single twisted-pair backbone.
Recomendado
USB HID / CDC Peripherals
The integrated USB 2.0 full-speed OTG controller on the PIC32MX534F064LT-V/PF enables HID keyboard/mouse firmware, CDC virtual COM ports, and mass-storage devices without external PHY ICs. The 64 KB Flash holds Microchip's free USB stack (USB Device, Host, or OTG), while the 16 KB SRAM handles three or more double-buffered endpoints. At 80 MHz, the MCU sustains 12 Mbps USB traffic while executing HID class drivers and consumer-side logic. A typical layout places the 33-ohm series resistors within 5 mm of the USB D+/D- pins, with a 4.7 uF VBUS capacitor and 15 kohm pull-down on D-.
Recomendado
Industrial CAN Sensor Hubs
Industrial sensor hubs that aggregate multiple analog or digital sensors onto a CAN backbone benefit from the PIC32MX534F064LT-V/PF's combination of USB OTG (for configuration), CAN 2.0B (for backhaul), and 16-channel 10-bit ADC (for analog sensing). The 4-channel DMA moves ADC samples to RAM without CPU intervention, freeing MIPS for CAN message handling. Engineers use the PIC32MX534F064LT-V/PF in 24V industrial cabinets with on-board isolated CAN and USB, where its V-grade temperature rating ensures operation in factory-floor thermal stress. The 80 MHz MIPS32 M4K core executes control loops at sub-millisecond intervals.
Recomendado
Consumer Audio Accessories
USB audio DACs, MIDI controllers, and headphone amplifiers commonly use the PIC32MX534F064LT-V/PF for USB audio class 1.0 streaming at 24-bit / 96 kHz. The 80 MHz MIPS32 core has sufficient bandwidth to run the USB audio isochronous endpoint driver alongside an I2S interface to an external DAC such as the PCM1794A. The 16 KB SRAM buffers USB isochronous packets, while 64 KB Flash stores USB descriptors and audio effect code. Designers benefit from Microchip's free USB audio framework that integrates with MPLAB Harmony.
Recomendado
HMI Touchscreen Controllers
The PIC32MX534F064LT-V/PF drives small QVGA (320x240) TFT displays with resistive touch by using its parallel master port (PMP) and the 10-bit ADC for touch sensing. The 64 KB Flash stores the graphics library, fonts, and UI state machine, while 16 KB SRAM holds the frame buffer for partial screen updates. CAN and USB OTG let the HMI communicate with a host controller or CAN keypad. Operating at 80 MHz, the MCU sustains 30 fps refresh with 16-bit color depth. The 100-pin TQFP exposes the 16 PMP data lines plus 85 GPIO for backlight PWM and rotary encoder inputs.
Recomendado
Data Acquisition with USB Streaming
Laboratory data-acquisition front-ends and portable measurement instruments use the PIC32MX534F064LT-V/PF to stream 10-bit ADC samples at 1 Msps over USB to a host PC. The 4-channel DMA offloads sample transfer between the ADC and the USB endpoint buffer, leaving the 80 MHz MIPS core free for digital filtering and protocol framing. With 16 KB SRAM the device holds a 2 ms acquisition buffer at full speed. The V-grade temperature range allows benchtop and field use from -40C to +105C. Designers pair the PIC32MX534F064LT-V/PF with external op-amps such as the MCP6002 for signal conditioning.

Notas de projeto
The PIC32MX534F064LT-V/PF operates from a single 2.3 V to 3.6 V supply. Place a 10 uF bulk tantalum or ceramic capacitor close to the VDD pin pair and a 0.1 uF ceramic decoupling cap on each AVDD and VDD pin. The 80 MHz core draws up to 70 mA under full DMIPS load; ensure your LDO can supply 100 mA peak. The VBUS pin (when used as USB host) draws 8 mA maximum for the pull-up on D+ or D-. Tie unused I/O to defined logic levels to avoid shoot-through currents.
The PIC32MX5xx family requires a 4-word Flash prefetch buffer to be enabled for 80 MHz operation; without it, Flash wait states cause instruction-fetch stalls and reduce effective performance by 30-40%. Configure the prefetch and wait-state bits in the CHECON register immediately after reset. Also, the 80 MHz PLL requires a stable 4-8 MHz reference clock - the internal 8 MHz RC is sufficient but drifts +/- 2% over temperature; use an external crystal for CAN or USB applications that need tight baud-rate accuracy.
Estimated: at 80 MHz CPU clock with all peripherals active, the PIC32MX534F064LT-V/PF draws about 70 mA from a 3.3 V supply, giving 230 mW of power dissipation. With the 100-pin TQFP (14x14 mm) theta_JA of approximately 45 C/W (4-layer PCB), the junction-to-ambient rise is about 10 C above ambient. At the maximum +105C ambient, junction temperature reaches 115 C, which is below the 125 C maximum. The V-grade part is rated for -40C to +105C ambient operation; verify the actual junction temperature in your sealed enclosure using the device's on-chip temperature diode if available.
Route USB D+ and D- as a 90-ohm differential pair with a length match of +/- 0.5 mm. Keep the traces short (< 50 mm total) and use a continuous ground reference plane beneath the pair. Place the 33-ohm series termination resistors within 5 mm of the MCU pins. For CAN, route CANH and CANL as a 120-ohm differential pair with the same length matching rule, and place the MCP2562 transceiver within 10 mm of the MCU CAN pins to minimize EMI loop area.
Informações de conformidade
Microchip PIC32MX534F064LT-V/PF is RoHS compliant and lead-free. V-grade parts undergo extended temperature qualification but AEC-Q100 status must be confirmed against the specific lot's PPAP documentation; Microchip's PIC32MX5xx family datasheet does not list explicit AEC-Q100 qualification.
