PIC32MX230F064D-V/PT Visão geral
A PIC32MX microcontroller is a 32-bit MIPS-based MCU that bridges the gap between traditional 8/16-bit microcontrollers and higher-end ARM Cortex-M parts, while staying in the familiar PIC ecosystem with MPLAB X IDE and Harmony framework support. The PIC32MX family sits within the broader hierarchy of microcontroller (MCU) -> embedded processor -> semiconductor device, making it a strong fit for mid-complexity embedded designs that need higher throughput than 8-bit PIC MCUs but want Microchip's toolchain and longevity commitments.
Key features of this part include the high-performance MIPS32 M4K core with hardware multiply/divide, 1.6 ms programming-time Flash with self-programmability, a Charge Time Measurement Unit (CTMU) that supports mTouch capacitive touch sensing and 1 ns-resolution time measurement, an on-chip temperature indicator, and a 4-wire MIPS Enhanced JTAG interface for debugging. The 5V-tolerant I/O pins with selectable open-drain, pull-ups, and pull-downs simplify interface to legacy 5V logic.
Architecturally, the device combines a Harvard-style bus with separate instruction and data paths, a 5-stage pipeline, and tightly-coupled peripherals routed through PPS for flexible pin mapping. The USB 2.0 full-speed On-The-Go (OTG) controller, two I2S/SPI interfaces for audio codec connectivity, and the PMP for direct LCD/graphical display driving make it suitable for multimedia and human-machine-interface applications without external bus controllers.
Typical applications include USB peripherals and HID devices, audio playback systems with I2S DACs, low-cost graphical HMI panels driven by PMP, capacitive touch user interfaces (buttons, sliders, proximity sensors), and industrial control nodes requiring deterministic 32-bit processing at modest power budgets.
When designing with this MCU, ensure the VDD/VSS pair is properly decoupled with 100 nF ceramic capacitors placed within 5 mm of each supply pin, and that the 8 MHz internal PLL reference is configured correctly for the target peripheral bus speeds. The PPS feature lets you remap peripherals to most I/O pins, but you must respect pin-function constraints at reset.

Aplicações típicas
PIC32MX230F064D-V/PT é adequado para 6 aplicaçãos: USB HID Peripherals and Custom USB Devices, Audio Playback with I2S DAC, Graphical HMI with PMP LCD, Capacitive Touch Panels (mTouch / CTMU), Industrial Sensor Hubs and Modbus Nodes, IoT Edge Devices and Data Loggers.
USB HID Peripherals and Custom USB Devices
The PIC32MX230F064D-V/PT is purpose-built for USB applications because it integrates a USB 2.0 full-speed OTG controller with on-chip transceiver, eliminating any external PHY. At 40 MHz the M4K core sustains HID polling, CDC virtual COM, MSD bulk-only, and custom interrupt-driven USB workloads comfortably, while PPS lets designers map USB plus I/O functions to nearly any pin. The 64 KB Flash fits CDC + HID composite stacks with DFU bootloader, and the 16 KB SRAM buffers USB endpoint data without DMA thrash. Typical circuits place a 15 kohm pull-up on D+ for full-speed device mode and add ESD protection on VBUS. Compared with adding an external FTDI bridge, the on-chip USB slashes BOM cost and board area by roughly $1.50 and 80 mm2.
Recomendado
Audio Playback with I2S DAC
The PIC32MX230F064D-V/PT contains two independent I2S modules that drive external audio DACs such as the PCM1794A or PCM5102A, making it a low-cost 32-bit MCU platform for network-audio appliances and portable players. At 40 MHz the core generates I2S LRCK up to 192 kHz via the reference clock output, and DMA-driven I2S keeps the CPU free for user-interface tasks. The PMP peripheral and 64 KB Flash can hold small audio codecs, equalizer presets, and HTTP streaming buffers simultaneously. Designs typically route I2S BCLK/LRCK/DATA through PPS-mapped pins and add an external low-jitter crystal for MCLK to keep THD+N under 0.005%. Compared with a discrete USB-to-I2S bridge, the PIC32 adds user-interface and DSP headroom in one package.
Recomendado
Graphical HMI with PMP LCD
The PIC32MX230F064D-V/PT features a Parallel Master Port (PMP) that interfaces directly to character LCDs, TFT modules with 8-bit or 16-bit bus, and external graphics controllers, enabling compact graphical HMI panels without an external bus bridge. The 40 MHz core sustains 30+ FPS redraw rates on small QVGA TFTs when DMA-fed through PMP, and the 16 KB SRAM comfortably holds a full framebuffer for 320x240x16bpp panels at reduced color depth. The CTMU and 13-channel 10-bit ADC read back panel touch, rotary encoders, and analog sensors concurrently. Power dissipation typically stays under 100 mA active at 3.3V, keeping the part within industrial HMI thermal budgets. Compared with 8-bit PIC16 HMI designs, the '230F064D quadruples available MIPS per watt.
Recomendado
Capacitive Touch Panels (mTouch / CTMU)
The PIC32MX230F064D-V/PT integrates Microchip's CTMU core that drives mTouch capacitive-touch firmware libraries for buttons, sliders, proximity sensors, and guards - no external touch IC required. The CTMU provides 1 ns-resolution time measurement so designers can also use it for ultrasonic ranging, flow metering, or precision pulse generation with no extra hardware. With 34 I/O pins, a 64-pin-capable part-of-a-touch-channel count supports up to 17 touch electrodes with proper guarding, plus 17 spare pins for LEDs and UART control. The 1 Msps 10-bit ADC captures analog ambient-compensation channels concurrently with CTMU scans. Compared with discrete touch controllers, the on-chip CTMU cuts BOM cost by roughly $0.80 per node and simplifies firmware maintenance within MPLAB X.
Recomendado
Industrial Sensor Hubs and Modbus Nodes
The PIC32MX230F064D-V/PT is well-suited to industrial sensor hubs because it combines a deterministic 40 MHz MIPS32 core, two UART channels, two I2C ports for sensor I/O, a 13-channel 10-bit ADC, three analog comparators, and PPS that maps any peripheral to any pin. Industrial Modbus RTU gateways, multi-loop PID controllers, and 4-20 mA sensor aggregators run reliably on the 64 KB Flash / 16 KB SRAM budget, while the industrial -40C to +105C temperature range covers outdoor enclosures and machine cabinets. The CTMU provides precision timing for ultrasonic level and flow sensors, and the on-chip temperature indicator lets the MCU self-monitor PCB hotspots. Compared with 8-bit PIC16 industrial nodes, this part adds DSP headroom for filtering without inflating BOM cost.
Recomendado
IoT Edge Devices and Data Loggers
The PIC32MX230F064D-V/PT suits IoT edge nodes because it offers low 0.5 mA/MHz active current, USB device power, two UART/I2C buses for sensor/satellite connectivity, and PPS to remap peripherals as the BOM evolves. A typical battery-backed data logger uses the 10-bit ADC to sample sensors into the 16 KB SRAM ring buffer, then streams to USB or UART in bursts; the CTMU timestamp samples with 1 ns resolution. The industrial -40C to +105C range handles outdoor IoT installations, and the 64 KB Flash fits Microchip's Harmony TCP/IP Lite stacks for low-rate MQTT/HTTP edge nodes. Compared with adding a wireless MCU, the wired-USB design removes RF certification overhead and keeps total BOM under $3 in volume.

Notas de projeto
Place 100 nF ceramic decoupling capacitors on each VDD/VSS pair (pins 5/4, 20/19, 40/39, plus the secondary pair on the analog rail) within 5 mm of the MCU pins to suppress switching noise from the 40 MHz core. Add a bulk 10 uF tantalum or ceramic capacitor near VUSB (pin 43) to stabilize the USB transceiver supply, and tie the bottom metal plane of the TQFP externally to VSS for thermal dissipation per the family datasheet. Estimated: with all peripherals active at 40 MHz, expect ~20 mA core current and ~5 mA USB analog; total peak ~25 mA at 3.3V.
Route the USB D+/D- lines as a 90-ohm differential pair with matched length and no stubs; keep them away from switching signals to maintain signal integrity. The JTAG pins PGEC2/PGED2 (RB6/RB7) should be brought out to a header or Tag-Connect footprint for MPLAB ICD programming. The analog inputs (RA0-RA5, RB1-RB5) benefit from a ground-pour isolation moat to keep digital switching noise out of ADC measurements.
Do not assume the -V and -I suffixes denote different temperature grades on this device - both refer to industrial -40C to +105C; -E would be extended range. Do not exceed 3.6V on any pin even though the I/O is 5V-tolerant; the 5V tolerance refers to logic-level reading only, not driving. Always configure the PPS registers immediately after reset to map peripherals to the correct pins, since the default pin-out is not application-ready.
