Typical Applications
PIC32MX230F128H-V/PT is suitable for 6 applications: Automotive Body Control Module, USB Human Interface Device (HID), Graphics HMI with Parallel Master Port, Capacitive Touch Control Panel, Industrial Sensor Hub, Portable Data Logger with RTCC.
Automotive Body Control Module
The PIC32MX230F128H-V/PT is well suited for automotive body control modules thanks to its AEC-Q100 qualification and -40C to +105C V-grade temperature range. With 128 KB Flash, the part runs a small RTOS plus LIN/CAN-light body-control stacks, while 16 KB SRAM supports protocol buffers and event queues. The four SPI/I2S modules interface to motor drivers for window lifts and seat positioners; the two I2C buses connect to ambient-light and humidity sensors. USB OTG enables firmware updates via a service-port dongle. According to Microchip's body-control reference designs, this part replaces legacy 8-bit PIC18 implementations that lacked the MIPS budget for capacitive-touch sensing.

USB Human Interface Device (HID)
The integrated USB 2.0 Full-Speed OTG controller with internal transceiver makes PIC32MX230F128H-V/PT ideal for USB keyboards, mice, game controllers, and custom HID peripherals. Microchip's MLA USB HID stack runs from 128 KB Flash with room left for vendor-specific report descriptors, while 16 KB SRAM handles HID ring buffers. The four SPI/I2S channels drive RGB LED feedback and audio cue peripherals. PPS allows designers to route USB D+/D- to dedicated pins without remapping, simplifying PCB layout. Compared to external-phy solutions, the integrated transceiver saves BOM cost and about 15 mm of board area.
Recommended
Graphics HMI with Parallel Master Port
The Parallel Master Port (PMP) with dual read/write buffers enables PIC32MX230F128H-V/PT to drive small TFT LCDs in industrial HMI panels. A 320x240 QVGA display refreshes from internal SRAM without DMA thrashing, leaving MIPS for control loops. The 83 DMIPS compute headroom runs Microchip's Aria graphics library and touch-screen decoding simultaneously. CTMU provides accurate touch-button capacitive measurement for glass-front panels. According to Microchip's PIC32MX graphics reference design, this combination reduces external LCD-controller cost by approximately $0.80 per unit in volume.
Recommended
Capacitive Touch Control Panel
The integrated CTMU (Charge Time Measurement Unit) and 10-bit ADC let PIC32MX230F128H-V/PT implement up to 16 capacitive touch channels with sub-percent accuracy. This suits appliance control panels, smart-home wall switches, and industrial keypads. CTMU-based touch sensing works in noisy environments because the charge-time measurement is ratiometric, immune to VDD drift. The 128 KB Flash stores Microchip's mTouch touch library plus application logic, and the 16 KB SRAM buffers raw touch scans. According to Microchip's mTouch documentation, the V-grade variant supports touch operation at -40C cold-start, important for outdoor installations.
Recommended
Industrial Sensor Hub
Industrial sensor hubs aggregate data from multiple field sensors and forward it to a gateway or PLC. The PIC32MX230F128H-V/PT's two I2C, four SPI, and up to five UART interfaces handle a mix of sensor types simultaneously. 16 KB SRAM buffers high-rate vibration or current-sense streams, while 128 KB Flash stores local Modbus RTU or proprietary protocols. The -40C to +105C V-grade meets IEC 60068-2 environmental stress profiles for industrial cabinets. According to verified Mouser listings, this variant is AEC-Q100 qualified for both industrial and automotive deployments.
Recommended
Portable Data Logger with RTCC
Battery-powered portable data loggers benefit from the PIC32MX230F128H-V/PT's separate VBAT-powered RTCC domain, which keeps timekeeping alive while the main core is asleep. Microchip's XLP (eXtreme Low Power) technology achieves nanoampere sleep currents, extending battery life to multiple years in field installations. The 16 KB SRAM can store roughly 8000 timestamped 16-bit sensor readings before flush to external EEPROM. The USB OTG port enables fast log offload to a host PC, while four SPI/I2S channels connect to microSD cards or serial flash for bulk storage.

Key Differentiators
- AEC-Q100 qualification with V-grade -40C to +105C support (vs PIC32MX230F128H-I/PT)
- Pin-compatible Flash upgrade path to 256 KB and 512 KB (vs PIC32MX130F064H-V/PT)

Design Notes
Place 0.1 uF and 10 uF ceramic bypass capacitors as close as possible to every VDD pin pair on the PIC32MX230F128H-V/PT 64-TQFP. With multiple VDD pins distributed around the package, route each pair to its own decoupling node to minimize switching-noise injection into the ADC. The VUSB pin requires its own 0.1 uF + 4.7 uF network to keep USB signaling within the 480 mV VBUS ripple budget.
Use a continuous ground plane under the entire MCU. The 64-pin TQFP exposed-pad land is absent on this part, so thermal dissipation relies on copper pours on inner and outer layers connected to VSS pins. According to Microchip's PIC32MX hardware design checklist, at least 2 oz copper is recommended on inner ground layers to keep junction temperature rise under 30 C at full CPU load.
Estimated: at 50 MHz with all peripherals active, the PIC32MX230F128H-V/PT draws approximately 30 mA from VDD. Headroom calculation: VIN - VDD must allow the regulator to maintain 3.3 V at 30 mA peak load. Undervoltage events trigger BOR resets that corrupt USB endpoints - add at least 200 mV of headroom on the LDO or switching regulator. Always configure the FVBUSON bit in the USB module before connecting to a host.
