PIC32MX130F128H-50I/PT - 50MHz 32-bit MCU 128KB Flash | Microchip
MPN: PIC32MX130F128H-50I/PT ✓ نشطPIC32MX130F128H-50I/PT نظرة عامة
A 32-bit microcontroller (MCU) is a single-chip computer that integrates a high-performance processor core, program and data memory, and configurable peripherals. The PIC32MX130 family specifically occupies the low-cost, low-power entry tier of Microchip's PIC32 lineup - bridging 8-bit PIC16/PIC18 designs and the higher-end PIC32MX3/4/5/6/7 families. Within the broader taxonomy it sits under microcontroller -> embedded MCU -> 32-bit MCU -> MIPS M4K core device. The 50 MHz core delivers 83 DMIPS, comparable to legacy ARM Cortex-M3 parts in the same cost band, while keeping the 8-bit PIC instruction ecosystem familiar to legacy Microchip developers.
Key features include 128 KB single-cycle Flash with live update support, 16 KB SRAM, a 10-bit 1 Msps 13-channel ADC, a CTMU for capacitive touch and time measurement, two comparators, a 5-bit DAC, and PMP with dual read/write buffers for graphics or external memory interfaces. PPS remaps digital peripherals onto most I/O pins, easing PCB layout. The CTMU and mTouch capability enable capacitive touch sensing without external components.
Typical applications include industrial control (HMI panels, sensor hubs), consumer audio (Bluetooth speakers with I2S codecs), USB-to-UART bridges, graphical low-cost displays using PMP, capacitive touch key pads, and low-power IoT edge nodes. The 128 KB Flash / 16 KB RAM headroom supports IPv4 stacks and lightweight USB device firmware.
Design consideration: the device requires a 2.5 V or 3.3 V rail - many analog rails cannot be fed directly. Place a 0.1 µF + 10 µF bulk pair within 5 mm of VDD/AVDD pins and use a ferrite bead between VDD and AVDD to keep switching noise out of ADC measurements. Configure unused I/O as outputs low to minimize I_dd leakage.
This page combines distributor pricing, drop-in PIC32 alternatives, and practical design notes that the manufacturer datasheet alone does not provide - supporting faster part selection and PCB reuse decisions.

التطبيقات النموذجية
PIC32MX130F128H-50I/PT مناسب لـ 6 التطبيقs: Industrial HMI and Control Panels, Consumer Audio Devices with I2S Codecs, Capacitive Touch Keypads (mTouch), Low-Cost Graphical Displays via PMP, USB-to-UART Bridge and Protocol Converters, Portable Battery-Powered Sensor Hubs.
Industrial HMI and Control Panels
The PIC32MX130F128H-50I/PT is well-suited for industrial HMI panels and control boards thanks to its 50 MHz/83 DMIPS MIPS32 M4K core, PMP with dual read/write buffers for graphics displays, and CTMU for capacitive key inputs. The 128 KB Flash holds graphical firmware plus a TCP/IP stack for OPC-UA gateways, while the 13-channel 10-bit ADC reads analog sensors at 1 Msps. PPS remaps peripherals onto most I/O so PCB layout can route noise-sensitive analog away from switching traces. Industrial -40 to +85 °C operation matches the IEC 60068 environmental grade required for factory floor deployment.

Consumer Audio Devices with I2S Codecs
Bluetooth speakers, smart soundbars, and aftermarket audio DACs pair well with PIC32MX130F128H-50I/PT because it integrates two I2S interfaces - one for input, one for output - alongside the four SPI modules used to configure external CODECs and DSP front-ends. The 50 MHz core sustains 48 kHz/24-bit streams without dropping samples, and 16 KB RAM is sufficient to double-buffer small audio frames. PPS flexibility lets the same TQFP-64 footprint route I2S lanes away from PWM motor-control lines in a smart-speaker enclosure, minimizing crosstalk without a board rework.
موصى به
Capacitive Touch Keypads (mTouch)
The PIC32MX130F128H-50I/PT integrates the CTMU peripheral that powers Microchip's mTouch capacitive-sensing library, enabling robust touch electrodes on glass or PCB surfaces without dedicated touch ICs. With 16 KB RAM and 50 MHz processing, the device can scan more than 32 electrodes at 100 Hz with hardware-averaged debouncing. PPS rerouting allows the touch sense pins to be placed where the industrial designer wants them rather than at fixed package locations, simplifying EMI-robust keypad layout.

Low-Cost Graphical Displays via PMP
The Parallel Master Port (PMP) on the PIC32MX130F128H-50I/PT drives small TFT or OLED displays with 8-bit or 16-bit parallel data, dual read/write buffers, and dedicated timing signals, eliminating external display controllers. At 50 MHz the core can refresh a 320x240 QVGA panel at 30 fps while reserving headroom for HMI logic. The 16 KB SRAM framebuffer accommodates partial-screen updates, and PPS lets the data bus land on any convenient pin group to simplify multilayer PCB routing.

USB-to-UART Bridge and Protocol Converters
When stepping up to USB is desired later, the PIC32MX130F128H-50I/PT shares its TQFP-64 footprint with PIC32MX230F128H-50I/PT, which adds USB 2.0 Full-Speed OTG. Engineers can prototype firmware on the PIC32MX130 and migrate the same PCB to PIC32MX230 once USB stack support is required, preserving firmware libraries thanks to shared MIPS M4K core. The five UART modules and dual I2C of PIC32MX130 make it a flexible protocol-converter choice even without USB today.

Portable Battery-Powered Sensor Hubs
Portable sensor hubs for environmental monitoring or asset tracking use the PIC32MX130F128H-50I/PT's low-power sleep modes (down to <1 µA with retention) combined with the 10-bit ADC to read temperature, humidity, or analog front-ends at low duty cycle. The 2.5-3.6 V supply range accepts a single Li-Ion cell with LDO regulation, and CTMU provides time-of-flight measurement for ultrasonic ranging. 128 KB Flash supports Bluetooth LE firmware stacks for IoT edge nodes; 16 KB RAM buffers sensor bursts before transmission.

ملاحظات التصميم
The PIC32MX130F128H-50I/PT requires a 2.5 V or 3.6 V supply and exposes separate VDD/AVDD/VSS/AVSS pin pairs. Place a 0.1 µF ceramic decoupling cap within 5 mm of every VDD/AVDD pin pair, and add a 10 µF bulk tantalum or ceramic on the main rail. A ferrite bead between VDD and AVDD prevents digital switching noise from coupling into the 10-bit ADC - critical for sensor-front-end designs that rely on clean ADC readings at 1 Msps.
Do not drive the I/O pins above VDD + 0.3 V even when the MCU is unpowered - latch-up risk on the CMOS I/O cells is well documented. Always use Peripheral Pin Select (PPS) to remap peripherals before configuring the pin - PPS unlock requires writing IOLOCK = 0 and using the sequence in DS60001168J section 12. Firmware must also clear IOLOCK after configuration to prevent runaway code from re-mapping peripherals inadvertently.
Route the 50 MHz crystal traces (RC14/OSC1 and RC15/OSC2) as short as possible - under 10 mm - with a ground guard ring on both sides, and place the load capacitors (typically 15-33 pF) within 2 mm of the MCU pins. For PMP-driven graphics interfaces, length-match the PMD[15:0] parallel data bus within 5 mm across all 16 lines to prevent skew at full CPU clock. Use a 4-layer PCB with continuous ground plane for best EMC performance.
