PIC32MX230F128H-V/MR Descripción general
An MCU (Microcontroller Unit) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM), and programmable peripherals such as ADC, timers, communication controllers, and I/O pins. The PIC32MX2XX family occupies the entry-level to mid-range tier of Microchip's 32-bit PIC32 portfolio, positioned between the PIC32MX1XX/5XX series and the higher-end PIC32MX3XX/4XX/6XX/7XX devices, all sharing the MIPS32 M4K core architecture for instruction-set compatibility across the family.
Key features include 128 KB Flash organized as 128K x 8, 16 KB RAM, a 10-bit ADC with up to 28 input channels, four SPI/I2S modules, two I2C modules, and USB 2.0 Full-Speed On-The-Go (OTG) capability. The device also integrates Peripheral Pin Select (PPS), a Parallel Master Port (PMP) with dual read/write buffers for graphics interfaces, and a Charge Time Measurement Unit (CTMU) for capacitive touch and time-based sensing applications.
The PIC32MX230F128H is built on a 5-stage pipelined MIPS32 M4K RISC core running at 40 MHz (the V-temp automotive grade part). The M4K core supports the MIPS16e ISA extension for code compression, achieving up to 1.65 DMIPS/MHz and 3.45 CoreMark/MHz, while consuming low core power. An integrated 8 MHz internal FRC oscillator provides clock flexibility, and the integrated USB 2.0 Full-Speed OTG controller enables direct device/host/OTG connectivity without external PHY.
Typical applications include automotive infotainment human-machine interfaces (HMI), USB peripherals (Human Interface Devices like keyboards, mice, and game controllers), industrial control panels with capacitive touch buttons (via CTMU), low-cost graphics interfaces through the PMP peripheral, and audio playback products using the I2S interface with external DACs. The combination of USB OTG, capacitive touch, and graphics PMP makes this part particularly attractive for automotive HMI and consumer electronics with HMI.
When designing with this device, ensure that the 2.3 V to 3.6 V supply rail is well decoupled with a 10 uF bulk + 0.1 uF high-frequency ceramic pair near each VDD pin. The PPS feature lets the engineer remap peripheral signals to most digital I/O pins, but once assigned, the pin map must be locked before code freeze to avoid PCB rework. The V temperature grade limits operation to -40C to +105C.

Notas de diseño
The PIC32MX230F128H-V/MR requires careful decoupling because the MCU operates across multiple supply domains: VDD (digital core), AVDD/AVSS (analog reference), and VUSB (USB transceiver). Place a 10 uF bulk capacitor at the board-level VDD input, plus 100 nF and 10 nF ceramic decoupling caps adjacent to each VDD/VSS pair on the QFN. For USB applications, VUSB requires its own 100 nF decoupling cap, and the D+/D- traces must be 90-ohm differential with a common-mode choke and ESD protection diode array such as USBLC6-2SC6.
The 64-pin QFN with exposed pad (EP) requires a continuous ground-plane land pattern on the top PCB layer that connects to the bottom EP via 9-12 thermal vias (0.3 mm drill, 0.6 mm pitch). Without proper EP soldering, the junction-to-ambient thermal resistance can exceed 60 C/W, and V-temp grade operation (up to +105C ambient) becomes marginal at full 40 MHz load. Estimated: at 30 mA core + 20 mA peripherals, internal dissipation is approximately 165 mW at 3.3 V; with theta-JA of 35 C/W (correctly soldered EP on 1 sq inch copper), junction rise is approximately 6C above ambient, leaving adequate thermal margin.
The QFN land pattern must follow IPC-7351 nominal-density guidelines with 0.45 mm pitch pads. The exposed thermal pad should be a single continuous land of approximately 7.5 mm x 7.5 mm with the via array specified in the Microchip package drawing. Maintain 4-mil trace and 4-mil space rules for the inner pin fan-out. The USB D+/D- pair must be routed as a 90-ohm differential with no splits and no vias; if layer changes are unavoidable, use back-drilled vias to maintain impedance. Keep the 32 kHz secondary oscillator crystal traces short (less than 5 mm) to avoid stray capacitance.
The most common design-in mistakes: (1) failing to enable the JTAG/ICSP debug pins (PGECx/PGEDx) properly during development, which bricks the MCU for in-circuit programming; (2) configuring the USB module without checking VBUS detect polarity, which prevents USB device enumeration; (3) leaving the MCLR pin floating, which causes random resets from EMI; (4) using PPS without documenting the pin map, which creates confusion in firmware maintenance; (5) ignoring AEC-Q100 documentation requirements for automotive designs (PPAP, IMDS, CM/PM compliance). Also note that the V-temp grade is specified up to +105C ambient but only at 40 MHz - if you need higher temperatures, derate clock frequency or move to PIC32MX1XX/2XX/5XX 64-pin QFN PIC32MX170 variants with extended temp support.
The 64-pin QFN has multiple high-speed signals (USB, PMP, I2S) that require controlled-impedance routing. USB differential impedance must be 90 ohms; PMP and I2S single-ended signals are typically routed as 50-ohm microstrip with reference ground 4-8 mils below. The CTMU inputs are analog and should be guarded by ground traces on either side to avoid digital coupling into touch measurements. The ADC analog inputs (ANx) should be routed away from switching nodes and have their own analog ground island tied to AVSS at a single point near the MCU.
