A microcontroller (MCU) is a single-chip computer that integrates a CPU core, volatile and non-volatile memory, and a wide range of peripheral interfaces (UART, SPI, I2C, ADC, timers, GPIO). The PIC32MX5XX family specifically targets the mid-range 32-bit embedded segment with deterministic MIPS processing, USB and CAN connectivity, and ample peripheral pin select (PPS) remapping flexibility. Within the broader taxonomy, PIC32MX MCUs belong to the Microchip 32-bit microcontroller hierarchy: PIC32MX -> 32-bit MCU -> microcontroller -> embedded processor -> semiconductor IC.
Key features include the Peripheral Pin Select (PPS) function that allows remapping of digital peripherals onto a wide range of GPIO pins, easing PCB layout constraints. Three I2S/SPI modules support audio codec and serial communication, while the Parallel Master Port (PMP) with dual buffers enables direct graphics interface to TFT LCDs. The Charge Time Measurement Unit (CTMU) enables touch-sensing and precise time-of-flight measurements, and a Real-Time Clock and Calendar (RTCC) module provides timekeeping with calendar functions. The on-chip 10-bit ADC with up to 16 channels serves mixed-signal sensing needs.
Typical applications include USB peripherals (HID, CDC, mass storage), CAN-connected industrial sensor nodes, audio playback interfaces via I2S, low-cost graphical HMI panels with PMP-driven LCDs, and consumer appliances requiring USB device charging and data logging. The 64-pin QFN package's compact 9x9 mm footprint and 0.9 mm height make it well suited for space-constrained designs.
When designing with this part, place decoupling capacitors (100 nF + 10 µF) close to each VDD/VSS pair and route the 48 MHz external crystal traces symmetrically with a grounded guard ring. The USB D+/D- lines require 90 Ω differential impedance and the DP pull-up resistor (1.5 kΩ to 3.3 V) must be enabled only in device mode. This page synthesizes distributor pricing, drop-in PIC32 alternatives, and practical design notes not found in the manufacturer datasheet alone.

典型應用
PIC32MX530F128HT-I/MR 適用於 6 應用s: USB HID Peripheral Device, CAN Bus Industrial Sensor Node, Audio Playback via I2S DAC, Graphical HMI with PMP-driven TFT LCD, USB Data-Logging Dongle, Touch-Sensing Control Panel with CTMU.
USB HID Peripheral Device
The PIC32MX530F128HT-I/MR is well suited for USB HID-class peripherals such as custom keyboards, mice, game controllers, and industrial input devices. The on-chip USB 2.0 Full-Speed OTG controller supports device, host, and dual-role operation, eliminating the need for an external PHY and reducing BOM cost. The 50 MHz MIPS32 M4K core provides 83 DMIPS, more than enough throughput to handle HID report polling at 1 kHz with full interrupt latency margin. The 16 KB SRAM comfortably holds USB endpoint buffers plus HID report descriptors. PPS remapping allows flexible PCB routing of D+/D- differential pair to any digital I/O for layout optimization.

CAN Bus Industrial Sensor Node
The PIC32MX530F128HT-I/MR's integrated CAN 2.0B controller with DeviceNet addressing support makes it a direct fit for industrial CAN sensor nodes such as temperature, pressure, and flow transmitters. The 50 MHz core plus 16 KB SRAM is sufficient to run a CANopen or DeviceNet slave stack with PDO mapping. The industrial -40 °C to +85 °C operating range is rated for factory-floor deployments. The 128 KB Flash accommodates the protocol stack plus custom application firmware. Pair with an external CAN transceiver such as MCP2561 for a complete isolated or non-isolated CAN node. PPS allows flexible assignment of CAN1 TX/RX to any digital I/O pin, easing PCB layout.

Audio Playback via I2S DAC
The PIC32MX530F128HT-I/MR's I2S interface module directly drives external audio DACs such as the PCM5102A or SGTL5000 for low-cost audio playback products. The three I2S/SPI modules support simultaneous codec data plus control, allowing stereo audio streaming from internal Flash or external SPI Flash. The 50 MHz core can DMA-feed I2S at standard 44.1 kHz / 48 kHz sample rates with negligible CPU load, leaving cycles for user interface or telemetry. The 16 KB SRAM provides audio buffer headroom for 100 ms or more of stereo data, supporting seamless playback. The PMP module can also drive a small GLCD for a combined audio-plus-display HMI.

Graphical HMI with PMP-driven TFT LCD
The PIC32MX530F128HT-I/MR's Parallel Master Port (PMP) with dual read/write buffers enables direct connection to small TFT LCDs for graphical human-machine interfaces in appliances, instruments, and industrial controllers. The PMP can interface to 8-bit or 16-bit parallel LCD controllers such as HX8347 or ILI9341 with minimal glue logic. The 83 DMIPS throughput allows smooth 30+ Hz UI rendering at 320x240 resolution with simple assets. Peripheral Pin Select makes it easy to route PMP control signals to spare GPIO, easing PCB constraints. Combined with the CTMU for touch-screen drive, the part is a one-chip solution for low-cost touch HMI.

USB Data-Logging Dongle
The PIC32MX530F128HT-I/MR is a strong choice for USB mass-storage or CDC-class data loggers used in medical, instrumentation, and field-recording applications. The USB OTG controller in device mode enumerates as a removable drive or virtual COM port without external ICs. With 128 KB Flash and 16 KB SRAM plus an external SPI Flash (such as SST26VF064B), the part can buffer days of sampled data before flushing to a host. The 10-bit ADC with up to 16 channels captures analog sensors. The RTCC timestamps every record with calendar accuracy even when the USB host is disconnected. Industrial temperature grade supports outdoor or mobile deployments.
推薦
Touch-Sensing Control Panel with CTMU
The PIC32MX530F128HT-I/MR integrates Microchip's CTMU (Charge Time Measurement Unit), enabling capacitive touch-sensing for buttons, sliders, and wheels without external touch ICs. The CTMU uses constant-current source and ADC timing to detect capacitance changes with sub-pF resolution, suitable for appliance control panels, automotive interior switches, and IoT wall controls. The 10-bit ADC plus CTMU supports up to 16 touch channels, and PPS simplifies PCB routing of sensor traces. Combined with the RTCC for time-based schedules and USB for configuration, this part is a single-chip solution for connected touch panels.

設計說明
Decouple each VDD/VSS pair with 100 nF + 10 µF ceramic placed as close as possible to the package pins; this is critical for USB Full-Speed operation where supply droop during packet transmission can cause VBUS-OVP false triggers. The PIC32MX530F128HT-I/MR operates from a single 2.3–3.6 V rail, so a clean 3.3 V LDO such as MCP1700 upstream of the MCU is recommended. Total quiescent current at 50 MHz is typically 22 mA/MIPS active plus ~10 µA sleep, so a 100 mA LDO is sufficient for most designs.
Route the USB D+/D- differential pair with 90 Ω characteristic impedance and matched length within 150 mil; place the 1.5 kΩ pull-up resistor on D+ close to the MCU pin and route only after the common-mode choke. Keep the 48 MHz crystal traces short and symmetric, with a grounded guard ring around the OSC1/OSC2 nets to avoid noise injection. Place the decoupling caps on the opposite side of the board directly under the QFN thermal pad with via stitching to a ground pour for low-impedance return paths.
The MCLR pin must be tied to VDD through a 10 kΩ pull-up and have a 100 nF decoupling cap to VSS for clean reset; a floating MCLR is the most common cause of intermittent brown-out symptoms. PPS remapping must be configured in software before any peripheral is used, otherwise UART/SPI/I2C signals appear as no-ops on the chosen pins. The Configuration Words must be programmed with the correct FNOSC, POSCMOD, and FWDTEN settings before USB or CAN can operate reliably at 50 MHz.
