PIC32MX230F256DT-V/PT 개요
A 32-bit microcontroller integrates a processor core, memory, and peripherals on a single chip. Within the embedded system hierarchy, the MCU sits at the control layer above discrete logic and below application processors. The PIC32MX family, based on the MIPS32 M4K RISC core, occupies the performance tier of Microchip's PIC portfolio, delivering roughly 1.4 DMIPS/MHz and about 83 DMIPS at maximum clock speed while consuming only 0.5 mA/MHz typical.
Key features include the 256KB self-programmable flash, 16KB SRAM, a 10-bit 1 Msps ADC, two I2S/SPI modules for audio codecs, Peripheral Pin Select (PPS) for flexible pin mapping, a Parallel Master Port for graphics interfaces, and USB 2.0 full-speed device/host/OTG on related family members. The -V suffix denotes the extended automotive temperature range.
The M4K core supports a 5-stage pipeline with prefetch and pre-cache acceleration, so code execution stays close to peak DMIPS even from flash. The RTCC module, 1 ns Core Timer, and five 16-bit timers support precision timekeeping and motor control timing.
Typical applications include automotive body and comfort modules, industrial control panels, touch-enabled consumer appliances using mTouch capacitive sensing, and audio accessory products driven by the I2S interfaces.
For design, budget flash headroom: at 40MHz the core delivers about 56 DMIPS, so plan worst-case interrupt latency with the PPS mapping locked during configuration. Program via ICSP with MPLAB SNAP or ICD tools.

일반적인 애플리케이션
PIC32MX230F256DT-V/PT 적합 용도: 6 애플리케이션s: Automotive Body and Comfort Modules, Industrial Control Panels, Capacitive Touch Consumer Appliances, Audio Accessories and Codecs, IoT Sensor Nodes and Gateways, Graphics-Interface Human-Machine Interfaces.
Automotive Body and Comfort Modules
The PIC32MX230F256DT-V/PT fits automotive body-control and comfort modules because it combines AEC-Q100 qualification with a -40C to +105C operating range, covering under-dash and near-engine temperature environments. Its 256KB flash accommodates protocol stacks for LIN-adjacent lighting and latch control, while five 16-bit timers and the 1 ns Core Timer generate precise PWM for LED dimming and motor-driven flaps. The 10-bit ADC reads potentiometer and NTC sensor inputs, and Peripheral Pin Select lets engineers route UART and SPI to the most convenient physical pins, simplifying harness-aware PCB placement in space-constrained modules.

Industrial Control Panels
In industrial control panels, the PIC32MX230F256DT-V/PT provides a 40MHz, 32-bit control core with enough 256KB flash for HMI logic, Modbus-style UART communication, and state-machine control. The extended temperature rating tolerates cabinet environments near power electronics, and the Parallel Master Port can drive segment LCD or graphics displays through external latches. Its 0.5 mA/MHz typical consumption keeps standby power low in always-on panels, while the 10-bit ADC with up to 1 Msps sampling handles current and voltage monitoring loops. Peripheral Pin Select allows UART and SPI rerouting without PCB respins during panel revisions.
추천
Capacitive Touch Consumer Appliances
The PIC32MX230F256DT-V/PT supports mTouch capacitive touch buttons and sliders using Microchip's charge-transfer sensing on its ADC channels, making it a single-chip solution for appliance fascia controls such as cooktops, coffee machines, and air purifiers. The 40MHz MIPS32 M4K core executes touch-decimation and debouncing algorithms alongside application logic within the 256KB flash and 16KB SRAM budget. Peripheral Pin Select frees convenient pins for touch electrodes, and the extended -40C to +105C range survives kitchen environments. PWM outputs drive indicator LEDs and buzzer feedback, reducing BOM count versus discrete touch controller plus MCU designs.

Audio Accessories and Codecs
With two I2S/SPI modules, the PIC32MX230F256DT-V/PT connects directly to audio codecs and digital amplifiers for Bluetooth-speaker controllers, headphone amplifiers with DSP presets, and intercom nodes. The 40MHz core handles audio metadata parsing, button UI, and volume table generation while the hardware I2S streams sample data to the codec without CPU bit-banging overhead. The 256KB flash holds multiple firmware features such as equalizer profiles, and the 10-bit ADC supports battery-voltage and key monitoring. Careful layout of the I2S clock lines with short traces preserves audio signal integrity in the 44-TQFP footprint.
추천
IoT Sensor Nodes and Gateways
For IoT sensor nodes, the PIC32MX230F256DT-V/PT acts as the local processing and communication hub: dual SPI/I2C buses interface digital sensors and radio modules, while the UART bridges to cellular or LoRa modems. The 256KB flash stores buffering, retry, and OTA-adjacent logic, and the RTCC with battery domain timestamps readings during sleep. At 0.5 mA/MHz typical, firmware can scale clock frequency dynamically to balance latency and battery life. The 10-bit ADC digitizes analog sensors, and Peripheral Pin Select adapts the same PCB to different radio daughterboards without hardware redesign across product variants.
추천
Graphics-Interface Human-Machine Interfaces
The Parallel Master Port (PMP) of the PIC32MX230F256DT-V/PT drives small TFT and monochrome graphic display modules through 8-bit or 16-bit parallel buses, achieving fast screen updates without a dedicated graphics controller. The 40MHz MIPS32 M4K core renders text, menus, and simple bitmaps into a framebuffer within the 16KB SRAM budget for quarter-VGA monochrome panels. SPI can alternatively drive serial displays where pin count is tight. Its extended temperature rating suits industrial HMI panels in outdoor kiosks and factory terminals, and the 256KB flash stores fonts, icons, and multi-language string tables for localized interfaces.

설계 노트
Supply the PIC32MX230F256DT-V/PT from a clean 3.3V rail within the 2.3V to 3.6V range. Fit a 0.1uF ceramic capacitor at every VDD/VSS pin pair, placed within 2-3 mm of the pins, plus 4.7uF-10uF bulk near the device. At 40MHz the core draws roughly 20 mA typical (0.5 mA/MHz per Microchip), so a small LDO such as the MCP1700 series is sufficient; Estimated: 3.3V x 20 mA = 66 mW of core power, negligible thermally even at +105C ambient. Follow the datasheet VCAP recommendation for the internal regulator.
Use the 44-TQFP land pattern per IPC-7351 with a 10x10 mm body and thermal relief under the center of the footprint. Because Peripheral Pin Select remaps digital functions in firmware, route spare traces from high-flexibility I/O to test points and headers before locking the PPS configuration. Keep ICSP programming pins (MCLR, PGD, PGC) on a 5-pin header with a 100 ohm isolation resistor on PGD/PGC when they share circuit functions, so MPLAB SNAP or ICD 4 can attach without fighting attached loads.
Do not exceed the 3.6V absolute supply even transiently - automotive load-dump on shared rails requires a TVS and series protection ahead of the LDO. Configure unused I/O as outputs low or inputs with pull-downs to avoid floating-pin leakage. Flash endurance and erase granularity mean firmware-update routines must write full rows; partial-word writes to configuration words can brick the device. When substituting family members, re-verify the PPS map and oscillator settings in code because peripheral availability differs between PIC32MX130/150/170/230 variants despite identical footprints.
Thermally the PIC32MX230F256DT-V/PT is undemanding: Estimated at 40MHz with 20 mA typical current, dissipation is about 66 mW, and with a typical 44-TQFP theta_JA near 50 C/W the junction rise is roughly 3C above ambient - comfortably within the -40C to +105C range. Thermal concerns only arise when many I/O pins source heavy simultaneous loads; budget per-pin current limits from the datasheet absolute maximums and spread loads across ports.
