PIC32MX534F064LT-I/PT Présentation
A 32-bit microcontroller (MCU) is a programmable processor core that executes instructions from on-chip flash memory, integrates RAM and a broad set of peripherals (USB, CAN, timers, ADC, I/O), and forms the central controller in an embedded system. Within the PIC32MX family, the MX5xx sub-family is positioned above the MX1/MX2 value line and below the MX6/MX7 high-performance line, targeting USB- and CAN-equipped industrial, medical, and consumer applications that benefit from MIPS M4K processing throughput.
Key features of this part include the 80 MHz MIPS32 M4K core with 5-stage pipeline, hardware multiply/divide, single-cycle multiplication, prefetch cache, and 64 KB flash that supports live updates through the ICSP interface. The 16 KB SRAM allows reasonable data buffering without external memory, while the four DMA channels offload data movement from the CPU. The USB 2.0 full-speed on-chip transceiver and the CAN 2.0b controller reduce external component count. The 100-pin TQFP package exposes up to 85 general-purpose I/O pins and supports parallel master port (PMP) operation for external bus expansion.
Typical applications include industrial USB-to-CAN bridges, HMI panels with USB device connectivity, embedded dataloggers, medical instrument controllers, and general-purpose 32-bit nodes in factory automation networks. The combination of USB device, CAN, and ample I/O makes this MCU a strong fit for industrial nodes that must communicate with both a host PC and a CAN fieldbus.
Designers should plan for a 3.3V core supply with typical 2.0V-3.6V operating range, place a 10 uF plus 0.1 uF decoupling network near each power pin pair, and follow Microchip's USB hardware design guidelines (impedance-controlled 90 ohm differential routing, common-mode choke) when the USB peripheral is enabled. The 'T' suffix indicates tape-and-reel, so pick-and-place programming and full production-line rework should follow standard JEDEC MSL-3 handling.

Applications typiques
PIC32MX534F064LT-I/PT convient pour 6 applications: Industrial USB-to-CAN Bridge, HMI Panel with USB Device Connectivity, Embedded Datalogger, Medical Instrument Controller, Factory Automation Network Node, General-Purpose 32-bit Embedded Controller.
Industrial USB-to-CAN Bridge
The PIC32MX534F064LT-I/PT is a strong fit for industrial USB-to-CAN bridges because its integrated USB 2.0 full-speed on-chip transceiver and CAN 2.0b controller remove the need for external PHY chips. The 80 MHz MIPS32 M4K core delivers the throughput needed for sustained 1 Mbps CAN traffic while handling USB bulk transfers to a host. With 16 KB SRAM the MCU can buffer multiple CAN frames, and the 64 KB flash accommodates USB CDC + CANopen or J1939 stacks. Power is supplied from the USB rail (5V) regulated down to 3.3V, and the 100-pin TQFP leaves ample GPIO for diagnostics LEDs and digital I/O.
Recommandé
HMI Panel with USB Device Connectivity
For human-machine interface (HMI) panels that connect to a host PC over USB, the PIC32MX534F064LT-I/PT offers an integrated USB device port plus enough RAM (16 KB) and flash (64 KB) to run a small LCD driver, touch-controller I2C driver, and a USB HID or vendor class stack. The 80 MHz core delivers smooth graphics update rates for 320x240 QVGA panels when paired with an external display controller. The 100-pin TQFP gives designers access to dedicated PMP pins for parallel display buses and to four DMA channels that offload frame buffer updates, leaving the CPU free for touch logic.
Recommandé
Embedded Datalogger
Embedded dataloggers benefit from the PIC32MX534F064LT-I/PT's 80 MHz processing headroom, 64 KB flash for storage code and tables, and 16 KB SRAM for sample buffers. The four DMA channels can autonomously move ADC samples into RAM while the CPU handles file system operations on an external SD card over SPI. The internal USB port is used to offload logged data to a host PC, and CAN connectivity allows time-stamping against a vehicle or machine CAN bus. Industrial -40C to +85C temperature grade covers most factory and outdoor cabinets without additional thermal hardening.
Recommandé
Medical Instrument Controller
Medical instruments such as portable spirometers, infusion monitors, and point-of-care analyzers benefit from the PIC32MX534F064LT-I/PT's deterministic 80 MHz MIPS M4K core, generous 16 KB SRAM for sample buffers, and on-chip USB for direct PC or charger interface. The 100-pin TQFP exposes the parallel master port for interfacing to TFT displays and the I2S peripheral for audio prompts in patient-facing devices. The industrial temperature grade (-40C to +85C) covers regulated medical use environments, while the V-grade variant PIC32MX534F064LT-V/PT extends to higher ambient for autoclave-adjacent electronics.
Recommandé
Factory Automation Network Node
As a node on a factory automation network, the PIC32MX534F064LT-I/PT supports both CANopen / DeviceNet fieldbus communication via its on-chip CAN 2.0b controller and USB host/device mode for local diagnostics or HMI pendant connectivity. The 80 MHz core runs protocol stacks alongside real-time control loops, and the 100-pin TQFP leaves dedicated pins for digital I/O, encoder feedback, and PWM outputs. Industrial temperature grade and 3.3V operation with 2.0V-3.6V tolerance simplify integration with 24V industrial backplanes through standard buck regulators.
Recommandé
General-Purpose 32-bit Embedded Controller
When a design requires a balanced 32-bit MCU with USB and CAN but does not need the larger flash of PIC32MX6/7 parts, the PIC32MX534F064LT-I/PT is a strong fit. The 64 KB flash and 16 KB SRAM comfortably hold a FreeRTOS port with lwIP or USB stacks, and the 100-pin TQFP exposes UART, SPI, I2C, PMP, and up to 85 GPIOs for board-level glue logic. Compared with Cortex-M3 parts at the same MHz, the M4K core offers comparable performance and the PIC32 ecosystem brings mature MPLAB X IDE, Harmony code generation, and the XC32 compiler.

Notes de conception
Place a 10 uF bulk plus 0.1 uF ceramic decoupling capacitor pair on every VDD/VSS pin pair. The 100-pin TQFP exposes five VDD and four VSS pins; each pair should have its own local capacitor placed within 5 mm of the pad. The 3.3V rail should source from a low-noise LDO such as MCP1700 if the upstream 5V comes from a switching converter - USB link reliability is sensitive to rail noise.
When using the on-chip USB transceiver, route D+/D- as a 90 ohm differential pair with controlled impedance, length-matched within 2 mm, and place a common-mode choke near the connector. Keep the VBUS sense pin isolated from switching power components. The CAN pins C1TX/C1RX need an external MCP2551 transceiver and a 120 ohm bus termination at each end of the CAN segment per ISO 11898.
Do not exceed the maximum VDD of 3.6V - the PIC32MX534 is not 5V tolerant on I/O. Use 74LVC4245 or similar level shifters when interfacing to 5V peripherals. Ensure MCLR is pulled high through a 10 kohm resistor and a 100 nF capacitor for noise immunity; floating MCLR causes spurious resets near noisy switching regulators.
The 80 MHz system clock generates up to 160 MHz edges on internal peripherals. Keep high-speed traces (PMP, SPI SCK, USB) short and routed over a continuous ground reference plane. Decouple the VUSB3V3 pin with a 0.1 uF + 4.7 uF pair as required by the internal USB voltage regulator - omitting the bulk capacitor causes USB enumeration failures.
Informations de conformité
RoHS and lead-free per Microchip product page. AEC-Q100 qualification not applicable for industrial -40C to +85C grade; choose V-grade PIC32MX534F064LT-V/PT for automotive-grade thermal margin.
