PIC32MX530F128LT-I/PF 概要
What is a PIC32MX microcontroller? PIC32MX is Microchip's family of 32-bit MIPS-based microcontrollers positioned between the 16-bit PIC24F/dsPIC line and the 32-bit Cortex-M based SAM family. In the wider taxonomy it is a microcontroller -> embedded microcontroller -> RISC microcontroller -> MIPS M4K core -> 32-bit MCU -> semiconductor. The PIC32MX series offers higher performance and richer connectivity than 8/16-bit PIC MCUs while remaining compatible with the MPLAB X IDE, Harmony framework, and XC32 toolchain, providing a familiar upgrade path for legacy PIC24/PIC32 customers.
Key features of the PIC32MX530F128LT-I/PF include a MIPS32 M4K core delivering up to 83 DMIPS at 50MHz, Peripheral Pin Select (PPS) for flexible pin assignment, a 16-channel 10-bit ADC with 500 ksps conversion rate, four 16-bit timers/counters, and a Parallel Master Port (PMP) with dual buffers for graphics or external memory interfacing. The CTMU allows precise time-of-flight and capacitance-touch measurement, while the RTCC keeps time with calendar function even in low-power modes. Operating voltage is 2.3V to 3.6V across an industrial -40C to +85C temperature range.
Typical applications for this device include USB peripherals (HID, CDC, mass storage), CAN-bus industrial nodes, audio playback/capture with I2S codecs, color TFT HMI panels using PMP, capacitive-touch user interfaces via CTMU, and battery-charging controllers. The combination of integrated USB, CAN, and PMP makes it especially attractive for industrial HMI, point-of-sale terminals, automotive infotainment peripherals, and medical instrumentation.
When designing with this part, note that the 'T' suffix indicates tape-and-reel packaging, 'I' indicates the industrial -40C to +85C temperature range, and the -I/PF variant runs at the conservative 40MHz speed grade rather than the full 50MHz -50I/PF variant. Pin-compatible PIC32MX5xx family members let designers scale Flash/RAM/peripherals without PCB rework.

主な用途
PIC32MX530F128LT-I/PF の用途: 7 件s: USB HID / CDC Peripherals, CAN Bus Industrial Nodes, Audio Playback with I2S Codec, Color TFT HMI Panel via PMP, Capacitive Touch Sensing via CTMU, Battery-Powered Real-Time Clock Controller, Point-of-Sale Terminal Peripherals.
USB HID / CDC Peripherals
The PIC32MX530F128LT-I/PF is well suited to USB human-interface and communication-device peripherals thanks to its integrated USB 2.0 Full-Speed controller with on-chip transceiver and 3.3V signaling. The 128KB Flash comfortably hosts the MPLAB Harmony USB stack including HID, CDC-ACM, and vendor-class drivers, while 16KB SRAM is sufficient for typical HID/CDC buffers. PPS remapping simplifies PCB routing of the D+/D- lines, and the 40MHz core provides ample headroom for USB polling plus application logic. Compared to external USB controllers, the integrated approach saves BOM cost, board area, and complexity.
おすすめ
CAN Bus Industrial Nodes
The PIC32MX530F128LT-I/PF integrates a CAN 2.0B controller ideal for industrial CANopen or DeviceNet slave nodes. Combined with an external MCP2551 or TJA1050 transceiver, the MCU can handle 1 Mbit/s CAN traffic with deterministic response times. The CTMU and 10-bit ADC support typical industrial sensor reading, while the industrial -40C to +85C temperature range suits factory-floor environments. The 100-TQFP package offers abundant I/O for parallel digital I/O expansion. Migration to PIC32MX5xx family variants preserves software investment while scaling Flash/RAM.
おすすめ
Audio Playback with I2S Codec
Two onboard I2S modules allow the PIC32MX530F128LT-I/PF to drive an external stereo DAC such as the PCM5102A or PCM1794A for high-fidelity audio playback. The DMA-driven I2S peripheral supports 16/24/32-bit samples at common 44.1/48 kHz rates, while 16KB SRAM is sufficient to buffer a few seconds of compressed audio. The MIPS32 M4K core decodes MP3, AAC, or ADPCM formats at low CPU load. PPS allows flexible PCB routing of BCK, LRCK, and DATA signals to any available I/O pin.
おすすめ
Color TFT HMI Panel via PMP
The Parallel Master Port (PMP) with dual read/write buffers drives 8/16-bit color TFTs and external graphics controllers directly from the PIC32MX530F128LT-I/PF, eliminating the need for an external display controller. Designers can render simple UI screens at reasonable frame rates using the 40MHz core. PPS allows the PMP data and control lines to be assigned to multiple pin groups for layout flexibility. Combined with the CTMU, this makes the MCU ideal for compact HMI panels in industrial controls and home appliances.
おすすめ
Capacitive Touch Sensing via CTMU
The PIC32MX530F128LT-I/PF Charge Time Measurement Unit (CTMU) provides precise capacitance measurement for capacitive touch buttons, sliders, and proximity sensors. Combined with the 10-bit ADC, the CTMU enables mTouch inductive and capacitive sensing libraries from Microchip. The 16-channel ADC and generous I/O count support up to 16 simultaneous touch electrodes. Industrial temperature range and integrated USB simplify building sealed-touch control panels for medical, white-goods, and instrumentation products.
おすすめ
Battery-Powered Real-Time Clock Controller
The integrated RTCC on the PIC32MX530F128LT-I/PF keeps accurate time/date even in Sleep mode with sub-1uA current draw from a backup battery or supercap. Combined with the USB and CAN interfaces, the MCU can log timestamped events and synchronize with a host PC. The wide 2.3V to 3.6V supply range allows direct 3V coin-cell operation. Multiple low-power modes (Sleep, Idle, Deep Sleep) and fast wake-up via RTCC alarm make it ideal for data loggers, metering, and security panels.
おすすめ
Point-of-Sale Terminal Peripherals
The combination of USB, CAN, PMP, I2S, and multiple UARTs on the PIC32MX530F128LT-I/PF enables compact POS peripherals like barcode readers, receipt printers, customer displays, and PIN pads. The 100-TQFP package provides the I/O count to interface LCD, keypad, magstripe reader, and printer simultaneously. USB Full-Speed connects the peripheral to the host terminal while UART/SPI connects to internal modules. Industrial temperature and Microchip long-term supply support multi-year POS deployments.

設計ノート
The PIC32MX530F128LT-I/PF requires a clean 2.3V to 3.6V supply; place a 10uF tantalum or ceramic bulk capacitor near each VDD/VSS pair plus a 0.1uF ceramic decoupling cap within 5mm of every supply pin. VUSB must be supplied with a stable 3.3V even in USB Device mode for the on-chip transceiver. Use an LDO such as MCP1700 for noise-sensitive applications. Add bulk capacitance on AVDD/AVSS if the ADC is used.
Route USB D+ and D- as a 90-ohm differential pair with matched length within 150 mil tolerance, and place the 15kohm D- pulldown resistor close to the D- pin. Keep high-speed digital signals away from the analog inputs (ANx). Use a four-layer PCB with continuous ground plane beneath the TQFP-100 footprint. The exposed pad is not present on TQFP-100, but a bottom ground pour under the MCU body aids thermal dissipation at high MIPS load.
PPS remapping must be configured early in startup code - forgetting this locks peripherals to default pins that may conflict with PCB layout. The MCLR pin requires a 10kohm pullup to VDD for reliable reset; if unused, tie it to VDD directly. The RTCC backup battery or supercap connection requires proper diode isolation to prevent reverse current. Flash write/erase operations require the unlock sequence and voltage within 2.3V-3.6V - verify regulator stability during write cycles.
Estimated: at maximum 40MHz CPU load with all peripherals active, the PIC32MX530F128LT-I/PF dissipates roughly 90mW (I-core ~2.3 mA/MHz). The TQFP-100 has theta_JA around 40 C/W on a standard 4-layer JEDEC test board, giving junction temperature rise under 4C above ambient at 85C ambient - well within the 125C maximum. No heatsink is required, but provide continuous copper pour under the device for margin in enclosed enclosures.
