PIC32MX230F064D-V/TL Overview
A microcontroller (MCU) is an integrated circuit combining a CPU core, program memory (Flash/ROM), working memory (RAM), and programmable peripherals on a single silicon die. PIC32MX230 devices sit in the mid-performance tier of Microchip's PIC32 family, between the lower-pin PIC32MX1xx series and the higher-memory PIC32MX3xx/4xx/5xx/7xx families. They are widely used in consumer electronics, industrial control, and USB-connected peripherals. PIC32 MCUs execute MIPS32 instructions and are supported by MPLAB X IDE, Harmony v3, and a free GCC-based toolchain.
Key differentiating features of the PIC32MX230F064D include full-speed USB 2.0 device/host/OTG, two I2S modules for audio codec interfacing, an on-chip temperature measurement channel, 1 ns high-resolution timer capture for precision timing, and mTouch capacitive touch support via the CTMU peripheral. The Peripheral Pin Select (PPS) feature allows flexible remapping of digital peripherals to any compatible I/O pin, simplifying PCB layout. The Parallel Master Port (PMP) enables direct interface to graphical LCDs and external parallel memory.
Typical applications include USB HID peripherals (keyboards, mice, custom HID), audio playback devices driving I2S DACs, low-cost graphical HMI panels using PMP, sensor hubs with mTouch buttons and sliders, and industrial controllers communicating over UART/SPI/I2C. The 40 MHz core, 64 KB program Flash, and 16 KB data RAM are well-matched to RTOS-based designs using FreeRTOS or Microchip Harmony.
Designers should ensure decoupling per Microchip's recommended 100 nF + bulk capacitor scheme, place the 8 MHz primary oscillator load capacitors close to the OSCI/OSCO pins, and observe the trace-length guidelines for the USB DP/DM differential signals to maintain USB compliance. Programming uses the 4-wire MIPS enhanced JTAG or ICSP interface.

Typical Applications
PIC32MX230F064D-V/TL is suitable for 6 applications: USB HID Peripheral Devices, Audio Playback and Codec Devices, Graphical HMI with PMP LCD, mTouch Capacitive Touch Sensor Hub, Industrial Sensor Hub and Data Logger, USB-to-UART/SPI/I2C Bridge Dongle.
USB HID Peripheral Devices
The PIC32MX230F064D-V/TL is well-suited for USB HID peripherals such as custom keyboards, mice, game controllers, and industrial input devices. Its on-chip USB 2.0 Full-Speed transceiver and integrated SIE eliminate the need for an external PHY, reducing BOM cost. With 64 KB Flash and 16 KB SRAM, it can host the Microchip MLA USB HID bootloader plus application firmware including debouncing, HID report generation, and LED/RGB animation. The 40 MHz MIPS32 core executes the USB stack at comfortable headroom, while PPS allows flexible pin assignment for matrix-scanned key switches.
Recommended
Audio Playback and Codec Devices
The PIC32MX230F064D-V/TL drives I2S audio codecs for consumer audio products, Bluetooth/Wi-Fi audio sink boards, and voice prompt modules. Its two I2S modules enable simultaneous DAC and ADC paths for full-duplex audio (e.g., headsets with microphone). The 40 MHz MIPS32 core processes 48 kHz/16-bit stereo streams (1.5 Mbit/s) with significant headroom for basic mixing and volume curves. The 16 KB SRAM comfortably buffers 80 ms of stereo audio at 48 kHz, while 64 KB Flash accommodates USB audio class firmware plus DSP effects.
Recommended
Graphical HMI with PMP LCD
The PIC32MX230F064D-V/TL's integrated Parallel Master Port (PMP) interfaces directly to graphical LCDs and OLEDs in compact HMI panels (appliance controls, instrument readouts, IoT thermostats). PMP supports 8-bit or 16-bit parallel data plus control signals, allowing full-frame buffer rendering to QVGA (320x240) displays. The MIPS32 core at 40 MHz drives sub-30 fps updates on small menus; for richer UIs the PIC32MX270F256D-V/TL with 256 KB Flash provides more headroom for fonts and bitmaps. The CTMU peripheral supports capacitive touch buttons alongside the display.
Recommended
mTouch Capacitive Touch Sensor Hub
The PIC32MX230F064D-V/TL supports Microchip's mTouch capacitive touch sensing via the on-chip CTMU (Charge Time Measurement Unit). It scans up to 28 channels for touch buttons, sliders, and proximity sensors with 1 ns timer resolution for precise charge-time measurements. The 105 C extended temperature rating makes it suitable for kitchen appliances, automotive interiors, and outdoor control panels. Combined with PPS, sensor traces can be routed freely across the PCB, simplifying layout versus fixed-pin MCUs.
Recommended
Industrial Sensor Hub and Data Logger
The PIC32MX230F064D-V/TL integrates multiple serial interfaces (4x SPI, 4x I2C, 6x UART) for sensor hub applications that aggregate data from accelerometers, environmental sensors, and serial instrumentation. Its 10-bit 1 Msps ADC samples analog sensors while the RTCC timestamps data with calendar accuracy. The wide -40 C to +105 C operating range and 5V-tolerant I/O simplify integration into 5V industrial backplanes. With 64 KB Flash, it stores the Microchip Harmony sensor framework plus local logging buffers in the 16 KB SRAM.
Recommended
USB-to-UART/SPI/I2C Bridge Dongle
The PIC32MX230F064D-V/TL is ideal for USB CDC-based bridge dongles that expose UART, SPI, or I2C buses to a host PC. Its USB 2.0 Full-Speed with on-chip transceiver connects directly to the host, while the PPS-multiplexed serial peripherals connect to the target. Common form factors include ESP32/STM32 flashing tools, industrial sensor configuration cables, and JTAG-over-USB adapters. The 64 KB Flash hosts the CDC class driver plus command interpreters with room for vendor-specific protocol extensions.

Design Notes
Place a 100 nF X7R ceramic decoupling capacitor within 2 mm of each VDD pin (pins 1 and 33) and a 4.7 uF to 10 uF bulk capacitor on the same net. The VUSB pin (pin 30) requires a separate 4.7 uF decoupling capacitor routed directly to the nearest VSS pin. Use a continuous ground plane under the VTLA-44 thermal pad; the central exposed pad (if present on the package revision) must be soldered to a top-layer GND pour for thermal dissipation and electrical reference.
Route the USB D+ and D- traces (pins 31, 32) as a 90-ohm differential pair with matched length (delta < 150 mil). Keep the pair away from switching power and I2S data edges. Add a series ferrite bead on VBUS if the board sources 5 V from the host, otherwise the internal USB transceiver may back-power the host. Per USB 2.0 Full-Speed specification, the DP/DM traces should reference a continuous ground plane on the layer immediately below.
Do not leave the MCLR pin (pin 44) floating; tie it to VDD through a 10 kohm pull-up resistor with a 100 nF capacitor to ground for noise debouncing. Failure to do so results in spurious resets in noisy environments. The OSCI/OSCO crystal (pins 42, 43) requires load capacitors per the crystal manufacturer's CL specification, placed within 3 mm of the pins; for 8 MHz fundamental mode, typical values are 15-33 pF on each side.
VDD must be monotonically rising from 0 V to at least 2.3 V at start-up; if a slow or oscillating power ramp occurs, the POR circuit may misbehave. Add a power-on reset supervisor or ensure the upstream regulator has adequate soft-start. The internal USB transceiver draws up to 30 mA peak during transmissions - budget accordingly for the 3.3 V regulator. Total active current is approximately 0.5 mA/MHz, so 40 MHz operation draws ~20 mA core current plus I/O load.
Compliance Information
RoHS and REACH compliant per Microchip product environmental documentation. Not AEC-Q100 qualified (automotive grade would require PIC32MX family members with explicit 'AEC-Q100' datasheet designation). Lead-free and halogen-free per Microchip material declaration. Conflict-mineral compliant per Microchip's CMRT filings.
