PIC32MX534F064H-I/MR 개요
Background: a microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, volatile data memory, and a rich set of on-chip peripherals such as timers, communication controllers, and analog blocks. The PIC32MX5xx family is a MIPS32 M4K-based line positioned at the high end of Microchip's PIC32 portfolio, adding USB and CAN connectivity for embedded networking. PIC32MX5xx belongs to the broader class of 32-bit flash microcontrollers and inherits the wider PIC32MX1xx/2xx/3xx/4xx/5xx/6xx/7xx family tree.
Key features include 64 KB Flash, 16 KB SRAM, an 80 MHz core delivering 1.56 DMIPS/MHz, 4-channel DMA, full-speed USB 2.0 device/host/OTG, CAN 2.0B, five 16-bit timers, two I2C, two SPI, two UART channels, a 16-channel 10-bit ADC at 1 Msps, and four parallel 16-bit comparators. The MR (VQFN-64 9x9) package exposes a thermal pad that reduces junction-to-board thermal resistance.
Architecturally, the M4K core executes a 5-stage pipeline with single-cycle multiply and hardware divide, while the peripheral bus matrix allows concurrent DMA transfers between peripherals and RAM without CPU intervention. The 16 KB SRAM is split between general-purpose RAM and dedicated Ethernet/USB/CAN buffer areas.
Typical applications include USB peripherals such as HID or CDC class devices, CAN-connected industrial sensor nodes, embedded TCP/IP stacks with the Microchip MLA, low-cost graphic LCD control with the PMP peripheral, and small HMI panels combining USB touch with CAN I/O expansion.
Designers should budget for the VQFN exposed-pad PCB layout (thermal vias to the inner ground plane are required for the -I industrial temperature range, -40 to +85 C) and provision a 12 MHz high-speed oscillator plus the 32 kHz low-power crystal for USB full-speed operation.

일반적인 애플리케이션
PIC32MX534F064H-I/MR 적합 용도: 6 애플리케이션s: USB HID / CDC Peripheral Devices, CAN 2.0B Industrial Sensor Nodes, Embedded TCP/IP Networking (with MLA Stack), Low-Cost HMI Panels with PMP Graphic LCD, USB-Connected Data Acquisition (DAQ) Modules, Educational / Maker 32-bit Development Platforms.
USB HID / CDC Peripheral Devices
The PIC32MX534F064H-I/MR's on-chip USB 2.0 Full-Speed controller with Device, Host, and OTG capability makes it ideal for USB Human Interface Devices (keyboards, mice, touch panels) and Communication Device Class peripherals (virtual COM ports, modems). The integrated 4-channel DMA offloads packet movement between the USB endpoint RAM and SRAM without CPU intervention, freeing the 80 MHz MIPS32 M4K core for application logic. Placed as the central MCU with a USB-B or USB-C connector on a 4-layer board, it delivers reliable enumeration while keeping BOM cost low.
추천
CAN 2.0B Industrial Sensor Nodes
The PIC32MX534F064H-I/MR's CAN 2.0B controller with 8 message buffers, paired with the -40 to +85 C industrial temperature grade, suits industrial sensor and actuator nodes on CANopen or DeviceNet networks. The 10-bit 1 Msps ADC handles analog transducer inputs, and the 4-channel DMA streams ADC and CAN messages concurrently without CPU stalls. Designers pair the MCU with a 3.3 V CAN transceiver like the MCP2551; the VQFN-64 exposed pad enables reliable thermal performance in sealed industrial enclosures.
추천
Embedded TCP/IP Networking (with MLA Stack)
Combined with the Microchip MLA TCP/IP stack and an external ENC28J60 or ENC424J600 Ethernet controller over SPI, the PIC32MX534F064H-I/MR delivers a low-cost embedded web-server or MQTT client. The 80 MHz core and 16 KB SRAM are sufficient for small concurrent TCP connections and a simple HTTP server. The 64 KB Flash holds the MLA stack plus application logic. Two SPI peripherals allow simultaneous Ethernet and peripheral expansion, with the 2.3-3.6 V supply eliminating the need for a separate regulator rail.
추천
Low-Cost HMI Panels with PMP Graphic LCD
The PIC32MX534F064H-I/MR's Parallel Master Port (PMP) directly interfaces with small TFT or graphic LCD modules (up to 8-bit bus width) for low-cost HMI panels. The 80 MHz core and DMA offload pixel data to the LCD, leaving CPU cycles free for touch scanning and menu logic. The 53 available I/O drive keypad matrices or rotary encoders alongside the LCD data bus, while the CAN peripheral connects the HMI to an industrial controller backbone without extra silicon.
추천
USB-Connected Data Acquisition (DAQ) Modules
The PIC32MX534F064H-I/MR serves as the central controller in USB-tethered data acquisition modules, with the 16-channel 10-bit 1 Msps ADC capturing analog signals and the USB FS port streaming data to a host PC. The 4-channel DMA streams ADC samples directly to USB endpoint buffers, sustaining >100 ksps throughput even with CRC processing. The 16 KB SRAM buffers incoming ADC data between USB transactions. Industrial users in lab automation and portable instrumentation benefit from the small 9x9 mm VQFN footprint.
추천
Educational / Maker 32-bit Development Platforms
The PIC32MX534F064H-I/MR is widely used in maker and academic environments due to its support in MPLAB X IDE, MPLAB Harmony v3, and the Arduino-compatible chipKIT ecosystem. The combination of 80 MHz 32-bit performance, USB, CAN, and 53 I/O at a low price makes it ideal for teaching embedded C, real-time operating systems (FreeRTOS port available), and peripheral interfacing. Educators benefit from the rich Microchip application library, while hobbyists gain a real industrial-grade MCU in a hobbyist-friendly VQFN format.

설계 노트
Estimated: at VDD = 3.3 V, 80 MHz core, USB active, and I/O toggling at moderate load, the PIC32MX534F064H-I/MR draws approximately 60 mA (0.20 W). The VQFN-64 (MR) 9x9 mm package has a typical theta_JA of approximately 28 C/W on a 4-layer JEDEC test board with thermal vias under the exposed pad; junction-to-ambient rise is therefore ~5.6 C at full load, well below the 85 C industrial limit. Designers MUST solder the exposed thermal pad (pin EP) to a ground copper pad with multiple thermal vias to the inner ground plane to achieve this dissipation. Skipping the EP connection can raise junction temperature by 20 C or more at high CPU loads.
Place 0.1 uF decoupling capacitors as close as possible to each VDD pin (pins 2, 35, 40) and a single 4.7-10 uF bulk capacitor near the package. Keep the USB D+/D- trace lengths matched to within 150 mils, route them as a 90-ohm differential pair on the top layer, and do not cross them with clock signals. Per Microchip datasheet DS61143D Section 'Oscillator', the primary oscillator traces (OSC1/OSC2, pins 43/44) must be kept short and guarded with a ground ring to limit EMI. Provision an external 32.768 kHz crystal on SOSC pins for RTC use; route with the same short-trace discipline.
Three pitfalls to avoid. First, do not exceed 3.6 V on any I/O pin even though some PIC32MX ports claim 5V tolerance - the absolute maximum ratings table in datasheet DS61143D defines the safe limit and violations will degrade oxide over time. Second, when migrating to the larger PIC32MX575F512H-I/MR for more Flash, the interrupt vector table and address remapping differ; firmware must be rebuilt against the new linker script and the configuration bits re-validated. Third, the on-chip 8 MHz FRC drifts with temperature and is not USB-accurate; always engage the PLL with an external 8 MHz crystal for USB Full-Speed enumeration reliability.
Use the PIC32MX534F064H-I/MR's internal 1.8 V core regulator (powered from VDD) instead of supplying the core externally; this simplifies the BOM and matches the reference design. Add a 10 uF tantalum or ceramic + 0.1 uF decoupling on the VDD rail, and a 1 uF on the VDDPLL pin if present. For battery-powered designs, the Sleep and Idle modes drop core current to single-digit microamps; enable the on-chip voltage regulator's low-power state and disable unused peripherals (USB, CAN, ADC) before entering Sleep to minimize quiescent current per datasheet DS61143D.
