PIC32MX230F128HT-V/MR 개요
A 32-bit microcontroller (MCU) is an integrated circuit containing a processor core, program memory (Flash), data memory (SRAM), and configurable peripherals on a single die. PIC32MX230F devices belong to the PIC32MX1xx/2xx general-purpose family (MIPS32 M4K core) within the broader PIC32 microcontroller portfolio, which targets USB, graphics, and HMI applications with integrated connectivity and analog peripherals.
Key features include 128KB Flash (128K x 8), 16KB SRAM, Peripheral Pin Select (PPS) for flexible signal routing, Parallel Master Port (PMP) with dual buffers for graphics, hardware crypto engine (in select variants), 5 PWM channels, and a 16-channel 10-bit ADC. Industrial-grade -40C to +105C temperature range (V-suffix) ensures operation in harsh environments.
The MIPS32 M4K core executes most instructions in one cycle, delivering up to 1.56 DMIPS/MHz (83 DMIPS at 50MHz). The 5-stage pipeline and hardware multiply/divide accelerator enable deterministic real-time performance. PPS allows remapping of digital peripherals to most I/O pins, simplifying PCB layout and BOM reuse across family variants.
Typical applications include industrial control and HMI panels, USB device/host peripherals, audio playback with I2S codecs, low-cost graphics interfaces (PMP), sensor hubs with CTMU touch, and consumer appliances requiring USB connectivity. The integrated USB OTG full-speed controller eliminates external PHY chips.
When designing with this device, ensure the 64-pin QFN EP has sufficient PCB copper pour (minimum 1 sq inch) to dissipate heat and provide a low-impedance ground. Decouple VDD/VSS pairs with 100nF + 1uF ceramics placed within 3mm of each pin pair. Configure PPS before enabling peripherals to avoid spurious signals.

일반적인 애플리케이션
PIC32MX230F128HT-V/MR 적합 용도: 7 애플리케이션s: USB HID / CDC Peripherals, Audio Playback with I2S Codec, Industrial Control / Sensor Hubs, Low-Cost Graphics HMI Panels, Consumer Appliance Controllers, IoT Edge Devices with USB Programming, Educational / Maker Development Boards.
USB HID / CDC Peripherals
The PIC32MX230F128HT-V/MR's integrated USB OTG Full-Speed PHY and 40MHz MIPS32 M4K core deliver 83 DMIPS, suiting USB HID input devices, CDC virtual COM ports, and Mass Storage peripherals without an external PHY. The 128KB Flash holds USB stack plus HID report descriptors comfortably; 16KB SRAM buffers USB endpoint packets. PPS remapping lets designers route USB D+/D- away from sensitive analog. Compared to STM32F0 with separate USB, the integrated PHY saves 0.5 USD BOM and simplifies FCC/CE certification paths.
추천
Audio Playback with I2S Codec
The PIC32MX230F128HT-V/MR integrates two I2S modules for stereo codec connection, supporting 16/24/32-bit audio at standard 44.1/48 kHz sample rates. The 40MHz core with DMA drives I2S streams without CPU intervention, freeing MIPS for DSP effects. The CTMU module supports touch-key volume controls. Compared to PIC32MX130 (single I2S), this part enables true stereo with separate DAC/ADC paths - critical for headphone amplifier applications needing simultaneous playback and microphone capture.
추천
Industrial Control / Sensor Hubs
With 16-channel 10-bit ADC, CTMU touch sensing, and -40C to +105C industrial temperature range (V-suffix), the PIC32MX230F128HT-V/MR fits industrial sensor hubs and motor-control feedback loops. The PMP with dual buffers drives character LCDs or simple graphics interfaces for HMI panels. Five PWM channels support BLDC or stepper motor control with hardware fault inputs. PPS flexibility lets PCB layout optimize analog/digital isolation. Robust against 4kV ESD (HBM) and 400V machine model per datasheet datasheet.
추천
Low-Cost Graphics HMI Panels
The Parallel Master Port (PMP) with dual read/write buffers interfaces directly to TFT LCD controllers or character/graphical displays, offloading display refresh from the CPU. Combined with SPI-based display controllers (using PPS-routed SPI), designers can drive QVGA panels at 30+ fps from 128KB Flash holding framebuffer and font tables. The 64-pin QFN EP exposes enough I/PG for both PMP data bus and touch input. Suitable for thermostat panels, appliance HMIs, and small industrial displays.
추천
Consumer Appliance Controllers
The PIC32MX230F128HT-V/MR's combination of USB connectivity, PMP for displays, and PWM for motor/solenoid control fits washing machines, coffee makers, and smart appliances. The 128KB Flash holds GUI assets and connectivity stacks (WiFi co-processor command libraries via UART/SPI). Five PWM channels drive BLDC motors or proportional valves. Operating from 2.5V or 3.3V simplifies integration with both legacy and modern power architectures. PPS flexibility reduces PCB layer count.
추천
IoT Edge Devices with USB Programming
Engineers building IoT edge nodes benefit from USB programming/debugging via the integrated USB OTG port, eliminating external debuggers in production. The 40MHz core with DMA supports TLS handshake on small payloads (sensor telemetry) and I2C sensor polling at sub-millisecond intervals. CTMU enables capacitive touch for wake-up buttons. The 16KB SRAM holds TLS buffers and sensor fusion state. Compared to MCUs without USB, the integrated programming interface reduces fixture cost by 1-2 USD per board.
추천
Educational / Maker Development Boards
The PIC32MX230F128HT-V/MR is widely available on hobbyist development platforms (chipKIT, Arduino shields via PPS) due to its 40MHz performance and USB support. MPLAB X IDE + XC32 compiler provide a free toolchain. The 128KB Flash is generous for student projects involving RTOS, file systems, or TCP/IP stacks via the integrated USB or external ENC28J60 Ethernet. PPS allows pin-function reassignment without board rework - ideal for learning environments.

설계 노트
The 64-pin QFN EP package dissipates heat primarily through the exposed pad (EP). At maximum CPU load (40MHz, peripherals active, USB transmitting), the part consumes ~50 mA at 3.3V (~165 mW). Without sufficient PCB copper pour, junction temperature can exceed 125C. Solder the EP to a copper pour of at least 1 sq inch with thermal vias (0.3 mm drill, 1 mm pitch) to inner ground plane. Reference: Microchip AN2340 (Thermal Management for QFN Packages).
Place 100 nF + 1 uF X7R decoupling capacitors within 3 mm of each VDD/VSS pair. The PIC32MX230 has 5 VDD/VSS pairs scattered across the package - each must have its own bypass cap, not shared with adjacent pairs. Keep analog supply AVDD/AVSS separated from digital VDD/VSS with a ferrite bead or filter resistor; place AVSS star-grounded to the EP. Reference: Application Note AN2330 (PIC32 Hardware Design Checklist).
Configure Peripheral Pin Select (PPS) registers BEFORE enabling the corresponding peripheral module. A peripheral enabled with no PPS mapping will drive signals onto random pins or remain silent. The unlock sequence (PPSLOCK bit) requires specific sequence: write 0x55 to PPSLOCK, then write 0xAA, then modify. Use MPLAB Code Configurator (MCC) to generate correct PPS setup. Common bug: KMS effects + USB not initializing when PPS is misconfigured.
USB Full-Speed requires 90 ohm differential impedance on the D+/D- traces. Route D+/D- as a length-matched differential pair with continuous ground reference beneath. Avoid stubs - the integrated USB PHY is sensitive to impedance discontinuities. Place 15 kohm pull-down resistors on D+/D- if used in host mode (peripherals typically have internal pull-ups). Reference: Microchip AN2331 (USB Design Considerations for PIC32).
The 64-pin QFN EP package has 0.5 mm pitch with a 9x9 mm body. Recommended land pattern: 30 mE pad length, 24 mE pad width, 0.5 mm pitch. NSMD (Non-Solder Mask Defined) pads are preferred for QFN packages. Maintain at least 0.2 mm clearance between pad edges and any signal traces under the package. Reference: IPC-7351 nominal land pattern with Microchip package drawing.
