MPN: PIC32MX230F064DT-V/PT ✓ Hoạt độngPIC32MX230F064DT-V/PT Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and peripheral interfaces such as timers, ADC, and communication buses. The PIC32MX230 sits within the broader taxonomy of embedded controllers (32-bit MCU -> MIPS-based MCU -> PIC32 family -> Microchip 8/16/32-bit portfolio), serving as a bridge between 8-bit PIC16/PIC18 designs and higher-performance Cortex-M parts. The MIPS32 M4K core delivers 1.5 DMIPS/MHz, supporting deterministic real-time control alongside rich connectivity for HMI and audio applications.
Key features include 0.5 mA/MHz active current for low-power designs, 1 ns high-resolution timer capture for precise measurements, on-chip temperature sensor, 34 general-purpose I/O pins with PPS remapping, and an automotive-grade -V temperature rating of -40 C to +105 C. The device supports both industrial (AEC-Q100 not mandatory) and automotive-grade deployments where extended thermal range and ruggedness are required, making it suitable for under-hood and harsh-environment nodes.
The architecture combines a 5-stage MIPS pipeline with single-cycle multiply and hardware divide, enabling deterministic interrupt latency for motor-control and audio codec loops. Internal oscillator options and flexible clock switching reduce external component count, while the PMP module directly drives TFT LCDs without an external gate-driver ASIC. USB 2.0 full-speed with on-chip transceiver and dedicated DMA channels simplifies tethered peripherals such as HID, CDC, and audio class devices.
Typical applications include automotive body electronics, consumer audio interfaces with I2S codecs, low-cost TFT HMI panels, capacitive-touch user interfaces, USB HID peripherals, and industrial sensor hubs. The combination of USB, audio interfaces, and graphics PMP within a compact 44-TQFP footprint makes the PIC32MX230 particularly attractive for cost-sensitive multimedia nodes.
When designing with this MCU, allocate adequate decoupling (100 nF per VDD/VSS pair plus a 4.7 uF bulk), keep the 40 MHz trace lengths short, and use the PPS feature to remap peripherals to convenient pins rather than re-routing the PCB. For USB designs, the 90 ohm differential pair must be routed with controlled impedance.

Ứng dụng tiêu biểu
PIC32MX230F064DT-V/PT phù hợp cho 6 Áp dụngs: Automotive Body Electronics Modules, USB Audio / I2S Codec Interfaces, Low-Cost TFT HMI Panels, Capacitive Touch User Interfaces, USB HID Peripheral Devices, Industrial Sensor Hubs.
Automotive Body Electronics Modules
The PIC32MX230F064DT-V/PT fits automotive body modules thanks to its AEC-Q100 qualification, -40 C to +105 C automotive-V temperature range, and 34 GPIO with Peripheral Pin Select. At 40 MHz it drives CAN-capable companion transceivers, body control logic, and LIN master tasks via UART. The 0.5 mA/MHz active current keeps sleep-mode quiescent drain low for always-on body nodes, while PPS allows pin reassignment without PCB rework when the BOM changes.

USB Audio / I2S Codec Interfaces
The PIC32MX230F064DT-V/PT serves USB audio class (UAC1) devices by combining USB 2.0 full-speed OTG with two I2S/SPIs. At 40 MHz it streams 16-bit/48 kHz stereo audio from a host to a delta-sigma DAC without DMA overruns. The integrated USB transceiver eliminates external PHY cost, while 16 KB SRAM buffers two stereo frames at 48 kHz. AEC-Q100 qualification makes it attractive for automotive infotainment auxiliary audio inputs.
Được đề xuất
Low-Cost TFT HMI Panels
The PIC32MX230F064DT-V/PT drives small TFT LCDs via the Parallel Master Port (PMP) without an external gate-driver ASIC. Up to 16 address lines and 8/16-bit data width let the PMP interface directly with ST7789V and ILI9341 controllers in 8-bit 8080 mode. PPS remaps PMP to convenient pins, while 64 KB Flash holds a full-color GUI framework plus custom fonts. The 44-TQFP provides enough I/O for both display and capacitive-touch buttons via mTouch.
Được đề xuất
Capacitive Touch User Interfaces
The PIC32MX230F064DT-V/PT supports mTouch capacitive-touch buttons and sliders via the on-chip CTMU and ADC, eliminating external touch ICs. Up to 13 ADC channels drive a 4x4 button matrix plus a 100 mm slider, all scanned within 4 ms at 40 MHz. The automotive -V temperature grade suits industrial control panels, while PPS frees up timer pins for backlight PWM control without conflicting with touch channels.
Được đề xuất
USB HID Peripheral Devices
The PIC32MX230F064DT-V/PT implements USB HID class devices (keyboards, mice, game controllers, custom HID) using the on-chip USB 2.0 full-speed transceiver and 1 KB of dedicated USB RAM. At 40 MHz the MIPS32 M4K core handles HID report parsing, debouncing, and LED/RGB animations within the 1 ms USB frame budget. The 64 KB Flash accommodates USB stacks plus vendor-specific report descriptors.
Được đề xuất
Industrial Sensor Hubs
The PIC32MX230F064DT-V/PT aggregates data from multiple sensors via I2C/SPI buses and forwards them via USB CDC or UART. Two I2C buses plus two SPIs allow simultaneous connection of a 9-DoF IMU, environmental sensor, and external ADC without bus contention. The 1 ns timer resolution enables precise timestamping for vibration and flow metering, and the -V temperature grade supports outdoor and factory-floor deployments.

Ghi chú thiết kế
Estimated: at 40 MHz active, typical core current is approximately 20 mA (0.5 mA/MHz x 40) plus USB and I/O drive. Total VDD budget is therefore around 25-30 mA. Add a 4.7 uF bulk capacitor and a 100 nF ceramic on each VDD/VSS pair within 5 mm of the pins. Use a low-noise LDO such as MCP1790-3002E for the analog AVDD rail if ADC accuracy below 1 LSB is required.
Route the USB D+/D- pair as a 90 ohm differential with matched length within 150 mil; keep total length under 50 mm and avoid splits in the reference plane below the traces. Place the 12 MHz crystal within 5 mm of OSC1/OSC2 with short traces and a grounded guard ring. The 44-TQFP thermal pad is not present; a copper pour under the package tied to VSS improves EMI performance by 2-4 dB.
Do not exceed 3.6 V on any pin including during hot-plug events on USB VBUS. MCLR must have a 10 kohm pull-up and a 100 nF capacitor to ground for proper reset; missing the capacitor causes spurious resets during ESD strikes. When using PPS, lock the PPS registers before sleep mode or peripheral mapping will reset on wake. For automotive -V grade designs, validate that your firmware complies with ISO 26262 ASIL requirements independently - the part itself is AEC-Q100 qualified, not ASIL rated.
Estimated: at 25 C ambient with continuous 40 MHz operation and full USB activity, junction temperature rise is approximately 25 C (using Microchip thermal model theta_JA = 60 C/W for 44-TQFP 4-layer JEDEC board). At +105 C automotive ambient this yields Tj of +130 C - within the +150 C max but with minimal margin. For continuous high-activity designs, consider the larger 64-pin variants with better thermal dissipation.
