PIC32MX230F064C-I/TL Обзор
A 32-bit MCU is a microprocessor in which the arithmetic logic unit, registers, and data paths are 32 bits wide, enabling single-instruction execution on 32-bit data and significantly higher throughput than 8-bit or 16-bit MCUs at the same clock rate. The PIC32MX2XX family sits inside the broader microcontroller taxonomy as: 32-bit MCU -> RISC MCU -> MIPS-based MCU -> embedded controller -> semiconductor IC. Devices in this class typically replace multiple 8/16-bit parts with a single integrated solution, providing deterministic interrupt latency, large linear address space, and richer peripherals for connected and graphical products.
Key features that distinguish the PIC32MX230F064C-I/TL include 19 general-purpose I/O pins, three analog comparators, a 10-bit 1 Msps ADC with up to 9 channels, four hardware DMA channels with automatic data-size detection, and Microchip's eXtreme Low Power (XLP) modes that drop active current below 0.5 mA/MHz. The on-chip full-speed USB 2.0 transceiver (with separate USB PLL) eliminates external PHY cost and board area, and PPS lets the developer remap most digital peripherals to any supported I/O pin.
Architecturally, the device combines a Harvard-style MIPS32 M4K core with separate Flash and SRAM buses, a five-stage pipeline, and MIPS16e compressed-code support that can shrink application code size by up to 40%. The integrated 8 MHz internal oscillator with PLL supports the 40 MHz system clock, while the on-chip voltage regulator accepts a 2.5V/3.3V supply and provides separate core and I/O rails.
Typical applications include USB peripherals (HID, CDC, mass storage), audio docks using I2S codecs, low-cost graphical HMI panels via PMP and TFT controllers, capacitive-touch user interfaces, and battery-powered sensor nodes that benefit from XLP sleep modes and the integrated RTCC for timekeeping. Designers frequently choose this part when they need on-chip USB and modest memory in a sub-6 mm² footprint.
When designing with this part, place the 36-VTLA exposed pad on a continuous copper pour tied to ground to keep junction temperature within the -40C to +85C industrial range. Use the PPS re-mapping feature early in the design phase to align peripheral pin assignments with PCB routing; once committed, the pin map can be revised in firmware with no board rework.

Типичное применение
PIC32MX230F064C-I/TL подходит для 6 применениеs: USB HID Peripherals (Keyboards/Mice/Gamepads), USB Audio Docks and Headsets, Capacitive Touch User Interfaces, Low-Cost Graphical HMI Panels, Battery-Powered Sensor Nodes, Industrial Control Modules (USB-CDC Bridge).
USB HID Peripherals (Keyboards/Mice/Gamepads)
The PIC32MX230F064C-I/TL is purpose-built for USB Human Interface Devices because its on-chip USB 2.0 full-speed OTG transceiver eliminates the need for an external PHY, freeing both BOM cost and PCB area. With 64KB Flash and 16KB SRAM, it comfortably hosts the Microchip USB stack plus a HID report descriptor and application firmware. The 40 MHz MIPS32 M4K core delivers the deterministic 1 ms USB poll-response timing required by HID class specifications, while the 19 GPIO pins (remappable via PPS) support matrix-scanned key arrays and LED indicators. Compared with 8-bit MCUs requiring a discrete USB serializer, this part integrates the entire USB physical layer, allowing single-chip mouse, keyboard, or gamepad designs.

USB Audio Docks and Headsets
In USB audio docks and headsets, the PIC32MX230F064C-I/TL acts as both USB device controller and I2S master, streaming 16-bit 48 kHz PCM from the host to an external DAC via one of its two I2S/SP I modules. The on-chip USB PLL runs the bus at 12 Mbps full-speed while the system PLL generates the I2S MCLK from the same 8 MHz internal oscillator without drift. 16KB RAM buffers 5-10 ms of audio without underrun, and PPS lets the designer route the I2S data/clock lines away from the USB DP/DN pair to minimize crosstalk. The 36-VTLA 5x5 mm package fits inside inline-cable dongles where competing MCUs would require a larger PCB.
Рекомендуется
Capacitive Touch User Interfaces
The PIC32MX230F064C-I/TL integrates the CTMU (Charge Time Measurement Unit) plus 3 analog comparators, enabling up to 9 self-capacitive touch channels on the same die without an external touch controller IC. At 40 MHz the CTMU performs a full scan of 9 channels in under 1 ms, supporting gestures and sliders with deterministic latency. The 64KB Flash holds Microchip's mTouch library plus application logic, and the XLP sleep modes drop quiescent current below 1 uA when the touch panel is idle. Designers using this part avoid the BOM cost and I2C-bus overhead of a discrete touch IC.
Рекомендуется
Low-Cost Graphical HMI Panels
The PIC32MX230F064C-I/TL drives low-cost TFT LCD panels through its Parallel Master Port (PMP), which supports 8-bit data plus control signals to popular controllers such as ILI9341 and HX8347. The 16KB SRAM is sufficient for 320x240x16b frame buffers written once and refreshed by PMP DMA, leaving the CPU free for UI logic. Peripheral Pin Select allows PMP remapping to free conflict-prone pins for SD card or USB, and the 40 MHz core keeps SPI-to-PMP bridges fast enough for 10 fps UI updates. The exposed-pad VTLA-36 footprint dissipates enough heat for full-speed operation with the LCD backlight driver active.
Рекомендуется
Battery-Powered Sensor Nodes
Battery-powered sensor nodes benefit from the PIC32MX230F064C-I/TL's eXtreme Low Power modes that draw under 0.5 mA/MHz active and below 1 uA in deep sleep with the RTCC running. The integrated 16-bit sigma-delta-friendly ADC plus CTMU digitize thermocouples, RTDs, or strain gauges without an external signal chain, and 4 DMA channels offload continuous sensor streaming while the CPU sleeps. With 64KB Flash, the firmware can include a full TCP/IP or LoRaWAN stack via SPI, leaving 16KB RAM for buffers. The 5x5 mm VTLA-36 footprint allows coin-cell powered designs where competing 32-bit MCUs would not fit.
Рекомендуется
Industrial Control Modules (USB-CDC Bridge)
In industrial control modules, the PIC32MX230F064C-I/TL functions as a USB-to-UART, USB-to-I2C, or USB-to-SPI bridge, with the on-chip USB full-speed transceiver presenting a CDC or vendor-class device to the host. Its two UART, two I2C, and two SPI peripherals handle most legacy field buses, while PPS keeps pin assignment flexible when the host board layout changes. The -40C to +85C industrial temperature grade supports factory-floor enclosures, and the 64KB Flash holds the bridge firmware plus diagnostic command parsers. Compared with FTDI-style bridges, this part reduces the BOM to one IC and gives engineers full firmware control over protocol and timing.

Заметки по проектированию
Estimated: At 40 MHz with all peripherals active and USB full-speed enumerating, the PIC32MX230F064C-I/TL draws roughly 25 mA from the 3.3 V rail. The VTLA-36 package has a theta_JA around 35 C/W on a 4-layer JEDEC test board, so the junction temperature rise is approximately 25 mA x 3.3 V x 35 C/W = ~2.9 C above ambient. To keep the die within the -40C to +85C industrial rating, solder the exposed pad (pin 37) to a continuous ground pour of at least 25 mm² on the top layer and stitch it down with 8-12 thermal vias to internal ground planes.
Per Microchip's PIC32MX hardware design checklist, route the USB DP/DN pair as a 90 ohm differential pair with no stubs, keep them shorter than 50 mm, and place the VBUS 4.7 uF decoupling capacitor within 5 mm of the VBUS pin. The 24 MHz crystal (or external clock) traces must be guarded on both sides by a ground hatched pour to avoid coupling noise into the USB PLL. PPS mapping should be finalized in firmware before PCB fab because some PPS remaps conflict with the ICSP programming pins PGED1/PGEC1 on RB0/RB1.
Do not leave the MCLR pin floating - tie it through a 10 kohm pull-up to VDD as required by the family datasheet, or the part will randomly reset in noisy environments. Also remember that the CTMU charge pump uses an external timing resistor on a dedicated analog pin; omitting it disables all capacitive-touch channels. Finally, the 1.8V internal core regulator needs a 10 uF + 0.1 uF capacitor pair on the VCAP pin (if exposed on the package variant); check the datasheet pinout for your exact device.
Информация о соответствии
RoHS compliant per Microchip product page; the -V (automotive temperature grade) suffix variants are not AEC-Q100 qualified, so this MPN family is intended for industrial/consumer use rather than automotive safety-critical applications.
