PIC32MX230F128LT-V/PF 概要
What is a PIC32MX microcontroller? The PIC32MX family is Microchip's first line of 32-bit microcontrollers built around the MIPS32 M4K core architecture. As 32-bit microcontrollers, PIC32MX devices fall into the broader hierarchy: microcontroller -> embedded MCU -> 32-bit MCU -> MIPS-based MCU -> semiconductor. They bridge the gap between 8/16-bit PIC microcontrollers and 32-bit ARM Cortex-M devices, offering familiar PIC development tools (MPLAB X, Harmony) while delivering significantly higher throughput and addressable memory.
Key features include USB 2.0 full-speed Device/Host/OTG with on-chip transceiver, Peripheral Pin Select (PPS) for flexible signal routing, two I2S and four SPI modules for audio and serial communications, a 10-bit ADC with up to 1 Msps conversion rate, and a Real-Time Clock Calendar (RTCC) module. The device also integrates a Charge Time Measurement Unit (CTMU) for capacitive touch sensing, three analog comparators, and a Parallel Master Port (PMP) with dual buffers for graphics interfaces.
From an architectural standpoint, the PIC32MX230F128L uses Harvard architecture with separate instruction and data buses, 5-stage pipeline, hardware multiply/divide, and zero-overhead loop control. The MIPS32 M4K core supports both standard MIPS and microMIPS compressed instruction mode, enabling efficient code density. The device operates from 2.3V to 3.6V across the -40C to +105C automotive temperature range (V suffix).
Typical applications include industrial automation (sensor interfaces, motor control), automotive body electronics (lighting, instrument clusters), USB peripherals (HID, CDC, custom devices), home automation and IoT nodes, consumer audio processing, and embedded HMI with graphic displays. The integrated USB transceiver eliminates the need for an external USB PHY, reducing BOM cost and PCB footprint.
When designing with the PIC32MX230F128LT-V/PF, allocate decoupling capacitance of 100 nF per power pin pair and a bulk 10 uF tantalum or ceramic near the VDD/VSS planes. Use PPS to remap peripherals to physical pins, simplifying PCB layout. For USB applications, route the D+/D- lines as 90-ohm differential pair with matched lengths. The -V speed grade supports the wider automotive temperature window (-40C to +105C).

主な用途
PIC32MX230F128LT-V/PF の用途: 7 件s: USB Sensor Hub, Automotive Body Electronics, Industrial HMI Display Controller, IoT Edge Node, Audio Processing (I2S), Home Automation Controller, Medical Data Acquisition Module.
USB Sensor Hub
The PIC32MX230F128LT-V/PF is a strong fit for USB sensor hubs because of its integrated USB 2.0 full-speed Device/Host/OTG controller with on-chip transceiver - no external PHY is required, reducing BOM cost. At 40 MHz MIPS32 M4K, the 83-DMIPS core can sustain USB CDC/HID polling alongside 1 Msps ADC sampling for multi-axis IMU or environmental sensor aggregation. The 16 KB SRAM comfortably holds HID report buffers plus a small sensor-fusion table.
おすすめ
Automotive Body Electronics
In automotive body and cabin ECUs, the PIC32MX230F128LT-V/PF provides AEC-Q100 qualified 32-bit processing with the -V grade's -40C to +105C operating window. The CTMU and 10-bit ADC can directly drive capacitive touch panels for door-handle and HVAC controls, while the PMP interface drives segment or small TFT displays. Hardware PWM and the RTCC module handle LED body lighting and time-stamped event logging respectively.
おすすめ
Industrial HMI Display Controller
For embedded HMI panels, the PIC32MX230F128LT-V/PF's Parallel Master Port (PMP) with dual buffers drives TFT displays up to QVGA resolution without external controller ICs. Its 4 SPI and 2 I2S peripherals support simultaneous touch-controller sampling and audio cue feedback. At 40 MHz, the core refreshes graphics from a small SPI flash with negligible CPU overhead, freeing cycles for user-application logic.
おすすめ
IoT Edge Node
The PIC32MX230F128LT-V/PF suits IoT edge nodes where local USB tethering is desired for commissioning or firmware update. Its 2.3V to 3.6V operation aligns with battery and bus-powered designs, and the RTCC plus low-power sleep modes enable duty-cycled sensors. The 4 SPI controllers allow direct connection of multiple sensor ICs (temperature, IMU, light, gas) without external multiplexer logic.
おすすめ
Audio Processing (I2S)
The PIC32MX230F128LT-V/PF has two I2S modules that interface directly with audio codecs, enabling sample-rate conversion, mixing, and effect processing without an external DSP. Combined with USB 2.0, it becomes a USB audio-class device (speaker, headset, or microphone). The 16 KB SRAM accommodates small PCM buffers at 48 kHz/16-bit stereo with minimal latency.
おすすめ
Home Automation Controller
In home-automation gateways, the PIC32MX230F128LT-V/PF integrates USB (for PC configuration), 6 UARTs (for RS-485 sensor buses), and 2 I2C (for sensor expanders) on a single die. The CTMU plus ADC supports on-board capacitive keypads, while the RTCC drives time-stamped event logs. The 128 KB flash fits Zigbee/Thread glue firmware plus a lightweight webserver on its USB Ethernet tether.
おすすめ
Medical Data Acquisition Module
The PIC32MX230F128LT-V/PF's 10-bit ADC at up to 1 Msps supports physiological-signal front ends such as pulse oximetry, body temperature, and bioimpedance monitoring. Its USB full-speed interface enables patient-side streaming to host diagnostic software, while the CTMU enables capacitive touch on medical device enclosures. AEC-Q100 qualification supports hospital-cart and patient-monitor deployment.

設計ノート
The PIC32MX230F128LT-V/PF operates from 2.3 V to 3.6 V with a 3.3 V typical supply. Decouple every VDD/VSS pair with 100 nF X7R ceramic placed within 5 mm of each pin pair, plus a 10 uF bulk tantalum or ceramic near the device. For USB bus-powered applications, route the 5 V VBUS through a voltage divider (typically 22 kohm/15 kohm) to the VBUS-sense pin to detect bus presence. Estimated: at full active load (40 MHz, USB + ADC sampling) the core draws roughly 30-45 mA, so 100 mA-rated LDO headroom is recommended.
Route the USB D+/D- differential pair with 90-ohm differential impedance, matched within 150 mil, and keep total length under 50 mm. Place a 15 kohm pull-down on D+ and a 1.5 kohm pull-up (settable via software) on D- for full-speed device enumeration. Keep the quartz crystal traces short and symmetric; the 100-pin TQFP package requires the outer quad of pins for analog ground, so separate AGND and GND islands with a single-point bridge under the IC.
Do not exceed the 3.6 V absolute maximum on any VDD pin - the USB VBUS pin is the only 5 V tolerant I/O. PPS remapping must be configured in code before the peripheral is enabled; the default pin mapping is non-trivial for SPI/I2S. The RTCC requires an external 32.768 kHz crystal with the recommended loading capacitors (typically 5-15 pF); omitting these prevents low-power RTCC operation. The 100-pin TQFP has thermal limits - estimated 0.5 C/W per Microchip thermal model, so 2 oz copper pours on top/bottom are recommended at high active loads.
Per Microchip's PIC32MX230F128L hardware design checklist, place the ICSP/ICD connector (6-pin SIL) at the PCB edge for programming access. Use a dedicated DEBUG pin row to route PGC/PGD cleanly with series 100 ohm ferrite beads to isolate programming noise from sensitive analog traces. The PGECx/PGEDx pins can be reconfigured as GPIO after programming, but PPS settings must preserve the default mapping until firmware boots.
