PIC32MX230F064B-I/ML - 40MHz 32-bit MCU, 64KB Flash | Microchip
MPN: PIC32MX230F064B-I/ML ✓ نشطPIC32MX230F064B-I/ML نظرة عامة
A microcontroller (MCU) is a single-chip computer containing a CPU, memory, and programmable I/O peripherals. The PIC32MX230 sits in the 32-bit MCU tier, above 8-bit/16-bit microcontrollers (e.g., PIC16, PIC24) and below application processors (e.g., Cortex-A, i.MX). Within the power-management hierarchy, MCUs integrate clock, reset, and supply supervision, reducing external component count for compact designs. As a member of the RISC microcontroller family, it executes most instructions in one cycle, delivering deterministic performance for real-time control.
Key features include 64 KB Flash, 16 KB SRAM, two I2S/SPI modules for codec and serial communications, Peripheral Pin Select (PPS) for flexible pin mapping, and a Parallel Master Port (PMP) for graphics or external memory interfacing. The device also integrates mTouch capacitive touch hardware, 1 ns high-resolution time measurement, on-chip temperature sensing, and five 16-bit general-purpose timers plus five input-capture/output-compare/PWM modules. Hardware multiply/divide and prefetch cache accelerate 32-bit math while keeping active current under 0.5 mA/MHz.
Architecturally, the M4K core runs instructions through a 5-stage pipeline with hardware MAC support, and PPS allows nearly every digital peripheral to be remapped to multiple pins. This decoupling of peripheral-to-pin assignments simplifies PCB layout, particularly in 28-pin QFN designs where pin count is limited. The 6x6 mm QFN package exposes a thermal pad to manage dissipation during sustained 40 MHz operation.
Typical applications include IoT edge nodes, USB audio devices, low-cost graphics HMI with PMP-driven TFT displays, capacitive touch user interfaces, and industrial sensor hubs. The combination of PPS, USB, and mTouch makes it especially strong in consumer appliances and human-interface products.
When designing with this part, plan pin assignments using the PPS tool in MPLAB X early; commit the mapping in firmware to lock the pinout. Ensure the exposed pad is soldered to a continuous ground pour for thermal and electrical performance.

التطبيقات النموذجية
PIC32MX230F064B-I/ML مناسب لـ 6 التطبيقs: USB Audio Device Controller, Capacitive Touch HMI, Industrial Sensor Hub, IoT Edge Node with USB Diagnostics, Low-Cost Graphics Display Controller, Portable Consumer Electronics.
USB Audio Device Controller
The PIC32MX230F064B-I/ML's integrated USB 2.0 Full-Speed device controller, two I2S/SPI modules, and 64 KB Flash make it well-suited for USB audio peripherals such as USB speakers, headsets, and digital microphones. Running the M4K core at 40 MHz, the MCU can manage USB isochronous audio streaming while feeding an external codec over I2S with deterministic 1 ms frame timing. PPS allows I2S bit-clock and word-select to be routed to any convenient I/O, simplifying PCB layout. With 16 KB SRAM, small USB descriptors and audio buffer pools fit comfortably. Compared to discrete USB-plus-DSP solutions, this single-chip approach reduces BOM cost and PCB area while keeping firmware in a single MCU environment.

Capacitive Touch HMI
The PIC32MX230F064B-I/ML integrates Microchip's mTouch capacitive touch hardware, allowing up to 12 touch buttons or a slider without external touch ICs. With 64 KB Flash and 16 KB SRAM, it can run touch scanning, debouncing, and a small GUI over PMP-driven TFT or segment LCD. PPS remaps each touch channel to any pin, freeing the designer from rigid pin assignment. Active current under 0.5 mA/MHz lets battery-powered HMIs run continuously for months on a coin cell. Compared to mechanical buttons, mTouch removes wear parts and supports sealed, water-tolerant front panels for appliances and consumer electronics.

Industrial Sensor Hub
The PIC32MX230F064B-I/ML operates from 2.3 V to 3.6 V across -40 °C to +85 °C, with 21 I/O pins supporting multiple UART, I2C, and SPI sensors in parallel. Five 16-bit timers and five input-capture modules make it ideal for time-of-flight, encoder, and pulse-counting measurements with 1 ns resolution. The 16 KB SRAM buffers short logging bursts before forwarding over USB or UART. PMP and I2S/SPI enable connection to TFTs or audio alarms for industrial operator panels. PPS lets each sensor interface land on the most convenient pins without redesigning PCB routing when sensors are added or removed.

IoT Edge Node with USB Diagnostics
The PIC32MX230F064B-I/ML's USB device, 64 KB Flash, and PPS flexibility suit IoT edge nodes that occasionally tether to a host for firmware updates or diagnostics. The M4K core runs 66 DMIPS at 40 MHz, enough for local sensor fusion, low-rate crypto, and MQTT-like protocol handling on small stacks. Two I2S/SPI interfaces connect to radio modules or sensors, while USB serves as a service port. Industrial temperature grade and 3.3 V tolerance match outdoor or factory-deployed nodes. Compared to bare Cortex-M0 parts, this MCU adds USB and larger memory at a competitive price point.

Low-Cost Graphics Display Controller
The PIC32MX230F064B-I/ML includes a Parallel Master Port (PMP) that drives small TFT, OLED, or segment LCD panels directly, eliminating an external graphics controller IC. With 64 KB Flash and 16 KB SRAM, the MCU can hold framebuffers for 320x240 QVGA monochrome or small color displays. PPS routes PMP data lines to convenient pins, easing PCB layout. Combined with the USB device for content updates, this chip replaces two-chip display-plus-USB designs in appliances and simple HMI products. Compared to SPI-only displays, PMP delivers several times the throughput for full-motion graphics.
موصى به
Portable Consumer Electronics
The PIC32MX230F064B-I/ML's sub-0.5 mA/MHz active current and 2.3 V minimum supply make it suitable for portable, battery-powered consumer devices like toys, fitness accessories, and remote controls. USB charging and data exchange are handled by the integrated Full-Speed device, while mTouch supports sealed touch interfaces. The 28-QFN (6x6 mm) footprint fits small enclosures, and the exposed pad ensures thermal stability during sustained 40 MHz operation. Compared to discrete 8-bit solutions, this 32-bit MCU delivers higher DMIPS per milliwatt and modern peripherals without raising cost.

ملاحظات التصميم
Solder the exposed thermal pad on the 28-QFN package to a continuous ground pour with at least 8 thermal vias for heat dissipation and electrical reference. Place 0.1 µF decoupling capacitors as close as possible to each VDD/AVDD pin, with a 4.7 µF bulk capacitor near the package. Keep the USB D+/D- traces (RB2/RB3) short, matched in length within 4 mm, and routed with 45° bends or arcs to maintain 90 Ω differential impedance for Full-Speed USB compliance.
Place a ferrite bead or small resistor (10 Ω) between VDD and AVDD if the analog peripherals (ADC, comparators) share the same 3.3 V rail as digital I/O. The PIC32MX230F064B-I/ML draws < 0.5 mA/MHz active and significantly less in sleep; an LDO with < 50 µA quiescent current (e.g., MCP1700) supports battery-powered designs. Decouple VDD with at least 1 µF ceramic plus a 10 µF bulk capacitor to handle USB inrush during bus attach events.
Use the Peripheral Pin Select (PPS) feature to remap UART, SPI, I2C, and PWM functions to convenient pins, which simplifies PCB layout and routing congestion on the 28-QFN. Lock the pin assignments in firmware using PPS configuration registers before peripheral initialization, as PPS mapping cannot be changed at runtime. Reserve PGED1/RB0 and PGEC1/RB1 for in-circuit programming; avoid assigning PPS functions that conflict with these debug pins or with MCLR (pin 28).
Do not exceed the 3.6 V absolute maximum on VDD or AVDD; add a TVS diode on USB VBUS if the design powers from USB. Configure the PLL for 48 MHz operation before enabling USB, as Full-Speed USB requires a precise 48 MHz clock. The MCLR pin must be pulled high with a 10 kΩ resistor and a 100 nF decoupling capacitor to ground; floating MCLR causes spurious resets. Avoid leaving unused I/O pins floating - configure them as outputs or enable the internal weak pull-ups to reduce EMI.
