PIC32MX230F128LT-V/PT 개요
What is a PIC32MX microcontroller? The PIC32MX family is Microchip's first 32-bit MIPS-based MCU line, positioned as a step up from 8/16-bit PIC microcontrollers for applications needing more compute, more memory, and richer connectivity such as USB, CAN, and graphics. PIC32MX230 sub-family members share the MIPS32 M4K core, Peripheral Pin Select (PPS) remapping, a Parallel Master Port (PMP) for graphics/QVGA interfaces, and an integrated Charge Time Measurement Unit (CTMU) for capacitive touch and time-of-flight measurement.
Key features of the PIC32MX230F128LT-V/PT include 128KB self-programmable Flash with live-update support, 16KB SRAM, 5 deep DMA channels, a 16-bit Parallel Master Port (PMP) for graphics or external memory, two I2S modules for codec/audio interfacing, four SPI (one with I2S-compatible variant), two I2C, five UART, USB 2.0 full-speed OTG, and CTMU. The integrated 10-bit 1 Msps ADC with up to 28 analog inputs enables precise mixed-signal designs without an external ADC. Peripheral Pin Select (PPS) gives designers freedom to remap digital peripherals to a wide choice of I/O pins, simplifying PCB routing.
Typical applications for the PIC32MX230F128LT-V/PT span USB peripherals, audio processing with I2S codecs, low-cost graphic HMI (QVGA via PMP), capacitive touch panels using CTMU, and automotive body controllers (AEC-Q100 qualified). The wide peripheral integration enables single-chip implementation of small appliances, sensor hubs, and connectivity bridges that previously required an external MCU plus companion logic.
Design consideration: when laying out the 100-TQFP PCB, place the VDDCORE and VDDPLL decoupling network (4.7 uF + 0.1 uF ceramic) within 3 mm of the dedicated pins and keep the USB DP/DM traces length-matched and 90 ohm differential. Refer to Microchip application note DS60001332 (PIC32MX Family Reference Manual) for clock and PLL configuration.

일반적인 애플리케이션
PIC32MX230F128LT-V/PT 적합 용도: 6 애플리케이션s: USB Peripherals and Audio Class Devices, Automotive Body and Cabin Controllers (AEC-Q100), Capacitive Touch HMI Panels (CTMU), Low-Cost QVGA Graphic HMI (PMP), Industrial Sensor Hubs and Data Loggers, Connectivity Bridges and IoT Edge Nodes.
USB Peripherals and Audio Class Devices
The PIC32MX230F128LT-V/PT is a strong fit for USB peripherals thanks to its integrated USB 2.0 full-speed OTG controller plus 16 KB SRAM and 50 MHz MIPS32 M4K core, eliminating the need for an external PHY in many designs. With USB audio class firmware, the two I2S interfaces connect directly to a stereo DAC such as the PCM5102A, enabling USB-to-I2S audio bridges. The 128 KB Flash accommodates USB stack plus class driver plus application code. Compared to switching to a dedicated USB interface IC, the integrated solution reduces BOM cost and PCB area while keeping latency low.

Automotive Body and Cabin Controllers (AEC-Q100)
With AEC-Q100 qualification and -40C to +105C operation, the PIC32MX230F128LT-V/PT is engineered into automotive body modules such as seat controllers, mirror adjusters, interior lighting nodes, and HVAC panels. The 10-bit 1 Msps ADC samples up to 28 analog inputs for sensor conditioning (temperature, current, position), the CTMU handles capacitive touch buttons, and the CAN-ready architecture interfaces with the vehicle bus. Compared to a 16-bit PIC24 alternative, the 32-bit MIPS core delivers 83 DMIPS for control-loop math and CAN message handling without straining real-time budgets.
추천
Capacitive Touch HMI Panels (CTMU)
The on-chip CTMU (Charge Time Measurement Unit) gives the PIC32MX230F128LT-V/PT native capacitive touch sensing with no external IC, supporting up to 28 touch channels directly multiplexed to ADC inputs. The Peripheral Pin Select (PPS) feature lets the designer route each touch electrode to any convenient I/O, simplifying PCB layout. With 128 KB Flash, designers can implement self-capacitance or mutual-capacitance touch libraries plus HMI state machines. Compared to a separate touch controller, integrating CTMU reduces cost, board area, and processor overhead.
추천
Low-Cost QVGA Graphic HMI (PMP)
The PIC32MX230F128LT-V/PT includes a 16-bit Parallel Master Port (PMP) with dual read/write buffers designed for direct interfacing with QVGA TFT LCDs up to 240x320 pixels, ideal for low-cost appliance HMI. The 50 MHz MIPS32 M4K core and DMA offload pixel data efficiently, leaving CPU cycles for UI logic. The 16 KB SRAM holds a partial frame buffer; full-screen buffer usually requires external SRAM via PMP. Compared to a higher-end PIC32MZ, the MX230 keeps BOM and toolchain cost low while still delivering smooth QVGA HMI.
추천
Industrial Sensor Hubs and Data Loggers
The PIC32MX230F128LT-V/PT's 10-bit ADC (up to 28 channels at 1 Msps), 5 DMA channels, and rich serial interfaces make it well suited as a multi-sensor aggregator or industrial data logger in factories, instrumentation, and process monitoring. The AEC-Q100 grade also enables deployment in harsh industrial environments. Compared to a discrete ADC plus 8-bit MCU, the integrated solution reduces BOM count, lowers power (typical 65 mA active at 50 MHz), and simplifies firmware. Storage is via SD card over SPI or external EEPROM.
추천
Connectivity Bridges and IoT Edge Nodes
With USB OTG plus 5 UART, 4 SPI, 2 I2C, and 2 I2S, the PIC32MX230F128LT-V/PT can act as a multi-protocol bridge between USB host (e.g. PC) and downstream peripherals (sensors, radios, codecs). Engineers commonly pair it with an MRF24WG0MA Wi-Fi module or an RN4020 BLE module to add wireless connectivity. The 128 KB Flash is sufficient for TCP/IP stacks (e.g. MLA) plus application logic. Compared to a single-radio SoC, this bridge architecture gives flexibility to swap radios without redesigning the application MCU.

설계 노트
The PIC32MX230F128LT-V/PT integrates an internal 1.8 V core regulator fed from VDD. Place a 4.7 uF X5R ceramic in parallel with a 0.1 uF ceramic on each VDDCORE pin, with traces shorter than 3 mm to minimize regulator instability. For VDDPLL (pin 1 on 100-TQFP), use the same 4.7 uF + 0.1 uF pair. Active current at 50 MHz with peripherals on is approximately 65 mA typical; budget at least 100 mA on the 3.3 V rail during firmware bring-up.
USB DP/DM traces must be 90 ohm differential, length-matched within 150 mil, and routed over a continuous ground plane. Place the USBLC6-2SC6 ESD protection array within 5 mm of the USB connector. Keep crystal traces short and symmetric, with load capacitors within 3 mm of the SOSCO/SOSCI pins to avoid oscillator jitter that would break USB timing.
MCLR must have a 10 kohm pull-up to VDD and a 100 nF cap to ground for reliable reset; omitting the cap causes spurious resets during in-circuit serial programming (ICSP). The Peripheral Pin Select (PPS) feature requires unlocking the PPSLOCK register sequence in firmware before remapping peripherals; lockouts cause confused pin behaviour at startup. Always configure Configuration bits (DEVCFG0/1/2/3) before exiting reset, not at runtime.
