PIC32MX230F256BT-V/SS Übersicht
What is a PIC32MX microcontroller? PIC32MX is Microchip's family of 32-bit MIPS-based microcontrollers, positioned between the 16-bit PIC24/dsPIC families and the higher-end PIC32MZ ARM Cortex-M based parts. Within the broader taxonomy, a PIC32MX belongs to microcontrollers (MCU) -> embedded processors -> semiconductors. The M4K core executes the MIPS32 instruction set with hardware multiply/divide and a 5-stage pipeline, delivering deterministic performance with low interrupt latency for real-time control.
Key features of the PIC32MX230F256BT-V/SS include 256KB (256K x 8) Flash program memory, 16KB SRAM data memory, 40 MHz maximum operating frequency, USB 2.0 full-speed device/host/OTG, 28 general-purpose I/O pins, a 10-bit 1.1 Msps ADC with up to 9 analog inputs, two UART modules, two SPI/I2S modules, two I2C modules, three 16-bit timers/counters, a CTMU for capacitance touch or precise time measurement, an RTCC, and a 5-channel 16-bit PWM. The -V suffix designates the automotive temperature grade of -40C to +105C and AEC-Q100 qualification.
Technically, the device uses a 2.3V to 3.6V single supply, supports MPLAB Harmony and legacy MPLAB C32 frameworks, and exposes program/debug through 2-wire ICSP. The SSOP-28 package (5.30 mm body width) is footprint-compatible with PIC24, dsPIC33, and PIC32MX230F064B (smaller Flash) variants, enabling code-base reuse and PCB family layout.
Typical applications include USB peripherals, automotive body and comfort modules, IoT sensor nodes, low-cost human-interface devices, capacitive-touch user interfaces via CTMU, industrial sensor conditioning, and consumer HMI with USB connectivity.
Designers should note that USB operation requires an external 48 MHz clock source or precise internal PLL configuration, and 3.3V regulation must remain within 2.3-3.6V for AEC-Q100-grade reliability.

USB Automotive Infotainment Modules
The PIC32MX230F256BT-V/SS fits USB automotive infotainment modules because its integrated USB 2.0 full-speed device/host/OTG controller enables direct connection to head units, mass storage, and HID-class accessories without an external PHY. The 256KB Flash accommodates USB MSD, CDC, and HID class stacks from MPLAB Harmony with margin for application code. The AEC-Q100 -V grade guarantees operation across -40C to +105C for cabin-mounted electronics. Compared to an external USB-serial bridge, the on-chip USB module reduces BOM cost by approximately $0.80 per node.

Capacitive Touch Human-Machine Interface
The PIC32MX230F256BT-V/SS is well suited for capacitive-touch HMIs thanks to its Charge Time Measurement Unit (CTMU), which converts sub-picofarad capacitance changes into precise time measurements without external touch ICs. The 10-bit ADC supports slider and wheel decoding, while 5 PWM channels drive LED backlighting and haptic feedback. AEC-Q100 qualification supports automotive HMI panels. The 28-SSOP package is small enough for touch-panel PCBs while still exposing 19 I/O for matrix scanning.
Empfohlen
Industrial Sensor Hubs with USB Diagnostics
The PIC32MX230F256BT-V/SS serves industrial sensor hubs needing USB diagnostics because its 2 UART, 2 SPI/I2S, and 2 I2C peripherals aggregate multiple sensor buses while USB exposes live diagnostics to a service laptop. The 40 MHz MIPS32 M4K core handles streaming aggregation with deterministic timing. The 2.3-3.6V supply range tolerates common 3.3V industrial rails and battery-backed UPS systems. Industrial-grade PLC and field-sensor designs leverage the AEC-Q100 stress-tested silicon for high-MTBF deployments.
Empfohlen
Battery-Powered IoT Sensor Nodes
The PIC32MX230F256BT-V/SS fits battery-powered IoT sensor nodes because its 2.3V minimum supply enables direct Li-ion cell operation through a low-dropout LDO or buck-boost, while the 40 MHz MIPS32 M4K executes MQTT-SN or CoAP stacks from the 256KB Flash. USB OTG allows convenient in-field firmware loading from a phone charger. Sleep current in deep-sleep mode drops to microampere levels, enabling multi-year coin-cell operation for slow-rate environmental sensors. AEC-Q100 stress testing ensures long-term reliability.
Empfohlen
Automotive Body Control Modules
The PIC32MX230F256BT-V/SS serves automotive body control modules such as mirror controllers, seat-position memory, and lighting drivers because the AEC-Q100 -V grade and -40C to +105C range meet cabin-electronics reliability targets. The 5-channel 16-bit PWM drives LED tail-lamps and motor bridges with precise duty-cycle control. The 10-bit ADC reads switch positions and current-sense amplifiers. USB enables dealership firmware reflashing via diagnostic connectors without external programmers.
Empfohlen
Consumer Point-of-Sale USB Keyboards
The PIC32MX230F256BT-V/SS fits consumer point-of-sale USB keyboards because the integrated USB HID class support and 256KB Flash accommodate multi-language layouts and macro firmware. The 28-SSOP package is hand-solderable for low-volume custom keyboards. RTCC enables time-stamping transactions, while 19 I/O pins support matrix-scanning of full 104-key layouts. Compared to 8-bit USB MCUs, the M4K core cuts scan-cycle latency by 3x and frees CPU bandwidth for LED animation.

Designhinweise
The PIC32MX230F256BT-V/SS operates from 2.3V to 3.6V and requires a stable VDD for USB operation. Estimated: at 40 MHz core clock the core current is approximately 30 mA plus peripheral current. Pair the MCU with a low-dropout regulator like MCP1700 (250 mA) and place a 100 nF decoupling capacitor within 5 mm of each VDD/VSS pair plus a 4.7 uF bulk capacitor on the 3.3V rail. USB applications additionally need a 1 uF capacitor on the VBUS line for transceiver stability.
Place a 100 nF decoupling capacitor adjacent to every VDD/VSS pin pair on the SSOP-28 package. Estimated: with 2 VDD and 2 VSS pins, four 100nF X7R ceramics in 0402 size minimize high-frequency noise. Add a single 4.7 uF X5R bulk capacitor near the package. For USB signals D+/D-, route as a 90 ohm differential pair with length matching within 2 mm; keep total length under 50 mm to meet USB 2.0 full-speed signal integrity.
Three common pitfalls: (1) Configuring the USB PLL with an 8 MHz primary crystal but enabling USB without checking the PLL lock status causes enumeration failures - always poll CLKLOCK before setting USBEN=ONTAIN. (2) Forgetting to enable the JTAGEN fuse bit disables ICSP and locks the device - Microchip recommends disabling JTAGEN only in production after programming. (3) Using the CTMU without calibrating the current source degrades touch accuracy; perform the CTMU calibration routine documented in the family datasheet.
Route the 8 MHz primary oscillator traces as short as possible and guard them with a ground pour to minimize EMI coupling into USB D+/D-. Place the crystal within 5 mm of the OSCI/OSCO pins, and add a 1MΩ parallel resistor across the crystal to dampen overdrive. Estimated: crystal load capacitor values should match CL specified by the crystal vendor (typically 18-22 pF for 8 MHz fundamental mode).
