PIC32MX230F256DT-V/ML 개요
What is a PIC32MX microcontroller? The PIC32MX family from Microchip combines a 32-bit MIPS M4K core with the familiar PIC peripheral ecosystem, offering up to 83 DMIPS performance while consuming only 0.5 mA/MHz typical. It bridges 8-bit PIC16/PIC18 and 32-bit ARM Cortex-M worlds, providing on-chip USB, mTouch capacitive sensing, and Parallel Master Port (PMP) for graphics interfaces, supported by MPLAB X IDE and Harmony framework.
Key features of the PIC32MX230F256DT-V/ML include a Parallel Master Port for graphics LCD/parallel memory interfacing, up to five 16-bit timers, RTCC, five CCP modules, and 1 ns resolution time measurement for high-precision capture. The PPS feature allows remapping of most digital peripherals to almost any I/O pin, simplifying PCB layout and reducing routing congestion in complex designs.
The PIC32MX230F256DT-V/ML targets applications requiring automotive-grade reliability with on-board USB, mixed-signal connectivity, and graphical display support. It provides ample headroom for user interface code while keeping power consumption low at 0.5 mA/MHz, and the QFN-44 exposed-pad package ensures robust thermal performance in sealed automotive modules.
Typical applications include automotive HMI modules with TFT LCD displays, USB-connected diagnostic tools, capacitive touch user interfaces, industrial sensor hubs with PMP-driven displays, and consumer audio devices requiring I2S codec interfaces. The automotive temperature grade (-40C to +105C) makes this part suitable for cabin electronics and in-cabin infotainment sub-modules.
When designing with the PIC32MX230F256DT-V/ML, ensure the exposed pad is soldered to a sufficiently large copper pour for thermal dissipation. Decouple VDD with 100 nF ceramic capacitors placed within 2 mm of each supply pin. Program and debug using MPLAB Snap, PICkit 4, or MPLAB ICD 4 over the ICSP interface.

설계 노트
Solder the exposed thermal pad of the 44-QFN package to a copper pour of at least 1 square inch connected to the ground plane. This serves both thermal dissipation and electrical ground reference. Per Microchip PCB layout guidelines, use thermal vias (0.3 mm drill, 1.0 mm pitch) under the pad to conduct heat to inner ground layers. Without proper pad soldering, junction temperature may exceed ratings at full 40 MHz operation.
Place one 100 nF ceramic decoupling capacitor within 2 mm of each VDD pin (pins 6, 12, 19, 25, 32, 36) and one bulk 10 uF tantalum or ceramic capacitor near the MCU. The VUSB pin (pin 39) requires a separate 100 nF decoupling capacitor for USB transceiver stability per Microchip USB design notes. Power sequencing is not required; the on-chip POR handles arbitrary ramp rates.
Do not exceed 3.6V on any VDD pin or 5V on any I/O pin to avoid latch-up. When using the USB peripheral, ensure the VUSB supply is present and stable before enabling USB module bits in the configuration registers. The MCLR pin (pin 40) requires a 10 kohm pull-up to VDD; floating MCLR prevents normal operation and may cause intermittent startup failures.
Keep USB D+ and D- traces (pins 37, 38) matched in length within 2 mm and routed over a continuous ground plane. Place the 15 kohm pull-down on D- as required by USB specification. Series termination resistors (27-33 ohm) on D+/D- near the MCU may be needed for long cable runs per USB 2.0 full-speed electrical compliance testing.
