MPN: PIC32MX130F256BT-I/ML ✓ Hoạt độngPIC32MX130F256BT-I/ML Tóm tắt
What is a PIC32MX microcontroller: PIC32MX is Microchip's MIPS32 M4K-based line of 32-bit microcontrollers that bridge 8/16-bit PIC legacy to higher MIPS throughput while preserving the MPLAB X toolchain and Harmony ecosystem. Within the taxonomy, PIC32MX sits below 32-bit microcontrollers -> microcontrollers -> microcontrollers and ICs -> semiconductors, and shares the 32-bit MCU category with ARM Cortex-M3/M4 devices.
Key features of the PIC32MX130F256BT-I/ML include 40 MHz / 50 MHz maximum operating frequency (40 MHz in this industrial -I/ML variant), 256 KB Flash program memory organized as 256K x 8, 16 KB SRAM, a 10-bit ADC, full-speed USB 2.0 device/host/OTG, two I2S/SPI modules for codec interfaces, a Parallel Master Port (PMP) for graphics, and a 1 ns high-resolution timer. Peripheral Pin Select (PPS) remaps most digital functions to any I/O, simplifying PCB routing.
The device integrates an on-chip temperature sensor, supports mTouch capacitive touch buttons/sliders, and delivers 83 DMIPS at 50 MHz with 0.5 mA/MHz typical active current. USB OTG, two UARTs, two SPI/I2S, two I2C, PMP, and a 16-bit timer/capture make it a versatile general-purpose platform.
Typical applications include USB HID peripherals, audio codec peripherals, embedded graphics with PMP, capacitive touch interfaces, low-cost 32-bit control for industrial sensing, and consumer products migrating from 8/16-bit PIC to 32-bit.
When designing with this part, keep the maximum supply at 3.6 V, place the decoupling regulator core (PPS remap oscillator bypass capacitor) close to VDD/VSS, and respect the 50 MHz maximum frequency rating.

Ghi chú thiết kế
Operate VDD between 2.5 V and 3.6 V. Place a 10 uF bulk tantalum or ceramic capacitor plus a 0.1 uF ceramic decoupling cap close to each VDD/VSS pin pair. For USB applications, add a ferrite bead + 1 uF + 0.01 uF decoupling network on VUSB to suppress switching noise. The 0.5 mA/MHz active current means typical 3.3 V operation at 40 MHz draws approximately 20 mA plus peripheral I/O drive.
Do not exceed 3.6 V on VDD or 5 V tolerance is NOT supported. Ensure the USB PLL receives a clean 12 MHz or 24 MHz crystal per AN1166 - the crystal must be within 50 ppm accuracy and load capacitance matched. The T-suffix is a packaging variant only (tape-and-reel), not a speed grade. The 40 MHz industrial -I grade must not be overclocked; use PIC32MX130F256B-50I/ML variants for 50 MHz.
The 28-QFN 6x6 mm package has an exposed thermal pad that MUST be soldered to the ground plane for thermal and electrical performance. Use a 5x5 via array (0.3 mm drill, 0.5 mm pitch) connecting the e-pad to a top-layer ground copper pour. Maintain a single continuous ground plane to reduce EMI and provide return paths for high-speed USB and I2S signals. Route USB DP/D- as a 90-ohm differential pair with matched length within 150 mil.
Use Peripheral Pin Select (PPS) to remap most digital peripherals, simplifying PCB routing and allowing multiple functions on the same pin footprint. For mTouch designs, place a guard trace (ground-connected) around each touch sensor with 1 mm gap to suppress stray capacitance. Keep analog inputs AN0-AN7 away from switching digital signals; place a ground moat between analog and digital sections.
