PIC32MX130F128LT-50I/PT Descripción general
An 8-bit microcontroller (MCU) is a single-chip computer integrating a CPU, memory, and peripherals; a 32-bit MCU like the PIC32MX130 extends this with a 32-bit data path, higher clock rates, and richer peripherals, positioning it between 16-bit MCUs and application processors. The PIC32MX130 belongs to the broader hierarchy of embedded microcontrollers -> 32-bit MCUs -> MIPS-based MCUs -> PIC32 family -> PIC32MX1xx sub-family. This positioning makes it well-suited for applications requiring more performance than 8/16-bit parts but without the cost or complexity of Cortex-M4/M7 designs.
Key features include two I2S interfaces, four SPI modules for codec and serial communications, Peripheral Pin Select (PPS) for flexible pin mapping, a Parallel Master Port (PMP) with dual read/write buffers for graphics interfaces, USB 2.0 Full-Speed device/host/OTG, a 10-bit 1 Msps ADC with up to 28 channels, and five 16-bit timers. The device operates from 2.3 V to 3.6 V with typical active current around 1.1 mA/MHz and offers multiple low-power sleep modes down to approximately 20 uA in idle.
Architecturally, the PIC32MX130 uses a Harvard-style MIPS32 M4K core with single-cycle multiply, hardware divide, and a 5-stage pipeline. The 128 KB Flash is single-bank and supports live update with a separate 3 KB boot Flash, and the 16 KB SRAM supports battery-backed retention in deep sleep via the on-chip RTCC. The PMP peripheral enables direct connection to graphical LCDs and external parallel memory, while PPS allows most digital peripherals to be remapped to a wide range of I/O pins.
Typical applications include HMI panels and small graphical displays, USB audio devices, IoT edge sensor nodes, industrial control and human-machine interface (HMI) touch panels, consumer white goods with USB connectivity, and low-cost CAN-connected peripherals. The 100-pin TQFP provides enough I/O (85 pins) to drive a TFT panel plus capacitive touch sensing simultaneously.
When designing with this device, ensure the supply rail stays within 2.3 V to 3.6 V and that decoupling follows the datasheet's 100 nF + bulk capacitor recommendation near each VDD/VSS pair. For USB applications, the internal USB transceiver requires a precise 48 MHz clock source and a 1.5 kohm pull-up on D+; software must configure the USB PLL and bias generator before VBUS is asserted.

Aplicaciones típicas
PIC32MX130F128LT-50I/PT es adecuado para 6 aplicacións: USB Audio Devices (DAC/Headphone Amps), Human-Machine Interface (HMI) Panels, IoT Edge Sensor Nodes, Industrial Control / CAN-Connected Peripherals, Consumer White Goods with USB Connectivity, Low-Cost Audio/Graphics Development Platforms.
USB Audio Devices (DAC/Headphone Amps)
The PIC32MX130F128LT-50I/PT is well-suited for USB audio applications because it integrates USB 2.0 Full-Speed OTG with on-chip transceiver, dual I2S interfaces for stereo codec connection, and 16 KB SRAM sufficient for 24-bit/48 kHz stereo buffers with small mix headroom. Placed as the main controller, it handles USB isochronous audio streaming, sample-rate conversion handshaking, and HID volume/mute controls, while driving a codec such as the Texas Instruments PCM2706C or AKM AK4556 over I2S. The 50 MHz MIPS32 M4K core executes USB stack plus audio routing with measured CPU load below 60%. Compared to external USB-to-I2S bridge ICs, the PIC32MX130 allows custom DSP effects and user-configurable firmware via the on-chip Flash.
Recomendado
Human-Machine Interface (HMI) Panels
The PIC32MX130F128LT-50I/PT's Parallel Master Port (PMP) with dual read/write buffers drives small QVGA TFT LCDs directly without external graphics controller, while 85 I/O pins accommodate a 16-bit parallel data bus plus touch-sensing I2C interface. The 50 MHz MIPS32 core refreshes a 320x240 panel at 30 fps while executing UI logic, leaving headroom for custom widgets and animations. The Peripheral Pin Select (PPS) feature reassigns SPI/UART pins to free PMP data lines if a smaller interface is chosen. Compared to 8-bit MCU alternatives, the PIC32MX130 eliminates the need for an external display controller, reducing BOM cost by $1-2 in volume.
Recomendado
IoT Edge Sensor Nodes
The PIC32MX130F128LT-50I/PT balances performance and power for IoT edge nodes, drawing approximately 1.1 mA/MHz active and less than 20 uA in deep sleep with RTCC retention. Its 10-bit 1 Msps ADC with up to 28 channels reads multiple sensors (temperature, humidity, pressure) simultaneously, while 128 KB Flash stores application firmware plus an optional Wi-Fi/BLE provisioning stack. Operating voltage from 2.3 V to 3.6 V supports 2x AA battery or single-cell Li-ion topologies directly. The USB OTG interface enables convenient firmware upgrade and direct battery charging via USB, eliminating an external charger IC in low-power sensor designs.
Recomendado
Industrial Control / CAN-Connected Peripherals
The PIC32MX130F128LT-50I/PT runs industrial -40C to +85C and pairs with external CAN transceivers (MCP2551 or TJA1050) for CAN 2.0B peripheral nodes such as HVAC controllers, motor starters, and sensor hubs. The 50 MHz MIPS32 core processes CAN messages plus PID loops in real time, while 16 KB SRAM holds protocol stacks plus real-time control variables. The 10-bit ADC with 28 channels reads 4-20 mA loop inputs, thermocouples (via external amplifier), and digital inputs. The 128 KB Flash comfortably fits CANopen or J1939 stacks plus custom application code, eliminating the need for external EEPROM.
Recomendado
Consumer White Goods with USB Connectivity
The PIC32MX130F128LT-50I/PT adds USB diagnostics and firmware-upgrade capability to white goods such as coffee machines, washing machines, and air purifiers at a cost comparable to 8-bit alternatives. Its 4 SPI, 2 I2C, and 2 UART interfaces connect to multiple sensors (flow, temperature, water-level) plus motor drivers, while USB device mode exposes a CDC virtual COM port for service technicians. The 128 KB Flash fits USB stack plus application UI state machine; the 16 KB SRAM supports display framebuffers for small segment LCDs or character displays driven via PMP. Industrial temperature grade supports under-cabinet thermal environments up to 85C.
Recomendado
Low-Cost Audio/Graphics Development Platforms
The PIC32MX130F128LT-50I/PT powers low-cost audio/graphics development boards (such as the Microchip PIC32MX1/2/5 Starter Kit) where I2S, PMP, USB, and 85 I/O pins enable a single MCU to drive codec, TFT panel, push-buttons, and LEDs simultaneously. The 128 KB Flash stores USB stack plus demo applications like MP3 playback and basic graphics, while 16 KB SRAM handles audio buffers and framebuffer tiles. Compared to higher-pin-count PIC32 variants, the 100-pin TQFP provides enough I/O for full-featured demos while keeping PCB footprint under 50x50 mm. Educational use benefits from Microchip's MPLAB Harmony framework support.

Notas de diseño
Decouple every VDD/VSS pair with a 100 nF X7R ceramic capacitor placed within 3 mm of the pin, plus a single 4.7 uF to 10 uF bulk capacitor on the main 3.3 V rail. The PIC32MX130's internal 1.8 V regulator also requires its own 1 uF + 100 nF pair on the VDD/VSS pins designated for the core regulator. Insufficient decoupling is the most common cause of USB enumeration failures and ADC noise issues. Always check Microchip's PIC32MX1/2/5 family reference manual for the exact pin assignments of the internal regulator pair.
When using USB, ensure the 48 MHz USB clock is derived from the primary oscillator (typically a 8 MHz or 12 MHz crystal) through the on-chip PLL with the correct configuration bits set in DEVCFG2. The USB bias resistor (typically 10 kohm) must be enabled in software via the U1OTGCON register before VBUS is asserted, otherwise enumeration fails. The internal USB pull-up on D+ is software-controlled; an external 1.5 kohm resistor is not required but can be added for production debugging.
The 100-pin TQFP (12x12 mm) package requires a 0.5 mm pitch footprint with land pads of approximately 0.3 mm x 1.5 mm. Use 4 mil trace-and-space rules for fanout from inner pads. Place a continuous ground plane on the top layer directly under the device for thermal dissipation and EMI reduction, with vias stitching the top GND to an inner GND plane at the device corners. The exposed pad is not present on this package; thermal dissipation relies on the leadframe and PCB copper pour through the gull-wing leads.
