PIC32MX230F064BT-V/SO 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash for program code and SRAM for data), and programmable peripherals onto one die. The PIC32MX230 belongs to the broader category of 32-bit microcontrollers (MCU -> 32-bit MCU -> MIPS32 MCU -> PIC32 family -> PIC32MX1XX/2XX sub-family). It targets applications that need deterministic real-time control with predictable interrupt latency, while keeping the development flow simple through the MPLAB X IDE and Harmony ecosystem.
Key features include two I2S/SPI modules for codec and serial audio, Peripheral Pin Select (PPS) for flexible peripheral-to-pin mapping, a Parallel Master Port (PMP) for graphics and external memory interfaces, an integrated Charge Time Measurement Unit (CTMU) supporting mTouch capacitive touch buttons and sliders, a 1 ns resolution time-measurement unit, and an on-chip temperature sensor. Multiple low-power modes (Idle, Sleep, Deep Sleep) and a Configurable Watchdog Timer with on-chip low-power RC oscillator improve system robustness. The 28-pin SOIC package supports 19 general-purpose I/O lines plus dedicated programming/debug pins for ICSP.
Typical applications include consumer and industrial control panels, capacitive touch user interfaces, low-cost audio playback using external I2S codecs, USB device HID bridges, sensor hubs, and small graphical HMI modules leveraging the PMP interface. Designers benefit from 4-channel hardware DMA, two UART, two I2C, two SPI/I2S, a 10-bit ADC, and five 16-bit timers/counters.
When designing with this part, place a 0.1 uF decoupling capacitor close to every VDD pin and follow Microchip's recommended board layout for the 28-SOIC variant. The wide-body SOIC footprint simplifies hand-soldering and rework in prototypes, while remaining suitable for volume assembly. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the standalone manufacturer datasheet.

主な用途
PIC32MX230F064BT-V/SO の用途: 6 件s: Capacitive Touch User Interface, Low-Cost Audio Playback (I2S Codec), Industrial Control Panel, Sensor Hub Module, USB HID Device Bridge, Small Graphical HMI (PMP LCD).
Capacitive Touch User Interface
The PIC32MX230F064BT-V/SO is well suited for capacitive touch HMI panels thanks to its integrated Charge Time Measurement Unit (CTMU) that supports Microchip's mTouch library. The CTMU provides 1 ns time measurement resolution, allowing reliable detection of button presses and slider positions through overlays up to 5 mm thick. With 64 KB Flash and 16 KB SRAM, the MCU comfortably runs touch scanning firmware plus a small UI state machine, while the 19 GPIO pins expose multiple wake-up sources for low-power touch wake. Design tip: route touch sensors on a separate ground-pour island and use the on-chip temperature sensor to compensate sensitivity across -40C to +105C operating range.
おすすめ
Low-Cost Audio Playback (I2S Codec)
The PIC32MX230F064BT-V/SO can drive external I2S audio codecs for playback applications such as voice prompts, sound effects, or simple music players. It includes two I2S/SPI modules, both DMA-capable, that can stream 16-bit 44.1 kHz audio with minimal CPU load (under 10% utilization). The 16 KB SRAM holds short audio buffers while the 64 KB Flash stores compressed audio assets. Compared to a software-PWM solution, dedicated I2S delivers lower EMI and cleaner audio quality. Connect the MCU's I2S bit-clock and word-select lines to the codec, with DMA handling background data movement from Flash to the I2S TX buffer.
おすすめ
Industrial Control Panel
The PIC32MX230F064BT-V/SO fits industrial control panels that need deterministic real-time control plus communication interfaces. Its two UART modules support RS-232/RS-485 links to PLCs or HMIs, while the two I2C ports drive sensor arrays and EEPROM storage. The -V temperature grade (-40C to +105C) tolerates factory-floor environments, and the 28-SOIC wide-body package simplifies hand-soldering during prototype bring-up. Hardware DMA offloads repetitive register-to-memory transfers, freeing the 40 MHz MIPS32 M4K core to handle the Modbus or proprietary control protocol stack.
おすすめ
Sensor Hub Module
The PIC32MX230F064BT-V/SO is a good fit for compact sensor hubs that aggregate readings from multiple I2C/SPI sensors and forward them over UART or USB. The 4-channel hardware DMA enables simultaneous sensor polling without CPU intervention, while the I2C fast-mode (400 kHz) and SPI up to the bus-clock rate keep latency predictable. The on-chip temperature sensor can be used alongside external sensors for environmental compensation. With only 19 GPIO pins, the PPS feature lets you remap peripherals dynamically as the hub supports different sensor boards.
おすすめ
USB HID Device Bridge
The PIC32MX230F064BT-V/SO in the PIC32MX1XX/2XX family can act as a USB Full-Speed device using its on-chip USB peripheral and integrated transceiver, presenting as a HID class device to a host PC. The 16 KB SRAM is sufficient for HID report buffers, and 64 KB Flash holds the device stack plus application logic. The dual I2S/SPI modules let the same firmware drive external LEDs or audio feedback in response to host commands. A common pattern is a USB-to-UART bridge with added GPIO control, leveraging the two hardware UART modules alongside the USB endpoint.
おすすめ
Small Graphical HMI (PMP LCD)
The PIC32MX230F064BT-V/SO exposes a Parallel Master Port (PMP) that directly drives small parallel LCDs (up to QVGA monochrome), making it appropriate for graphical HMI in appliance front panels, thermostat displays, and instrument readouts. The PMP can run in master mode with up to 16-bit data width, and DMA channels push frame-buffer data to the LCD with minimal CPU load. 64 KB Flash can store font tables and small bitmaps, while 16 KB SRAM serves as the active frame buffer for QVGA monochrome at 1 bpp. Pair with a small SPI-connected touch controller for complete HMI on one chip.

主な差別化要因
- Wide-body 28-SOIC for easier hand-soldering and rework （vs PIC32MX230F064BT-V/ML (QFN variant))
- V temperature grade (-40C to +105C) for automotive/industrial （vs PIC32MX170F256BT-I/SO)

設計ノート
Place a 0.1 uF decoupling capacitor as close as possible to every VDD pin (1, 13, 28) and a bulk 10 uF tantalum or ceramic capacitor near the package. The PIC32MX230F064BT-V/SO has multiple VDD pins that must all be connected; floating a single VDD can cause reset instability. For battery-powered designs, leverage the Deep Sleep mode (typical current ~1 uA) by gating the 40 MHz system clock and waking on CTMU touch or external interrupt.
The 28-SOIC wide-body package (7.5 mm body width) provides generous pad spacing for hand-soldering and rework, but still requires thermal relief on power pins to avoid dry joints during reflow. Keep PGECx/PGEDx traces short and routed away from high-frequency switching nodes to preserve ICSP debug reliability. Route the analog AVSS/AVDD pair (where used) as a star ground to minimize digital switching noise coupling into ADC conversions.
Do not assume pin names across PIC32MX families map 1:1 - the PIC32MX230F064BT-V/SO differs from the PIC32MX1XX/2XX 44-pin variants in exposed peripheral counts. Always verify the specific pinout in the family datasheet DS61168G before PCB layout. A common pitfall is omitting the external pull-up on the SDA1/SCL1 I2C lines, which the MCU does not provide internally. Also note that PPS mappings must be unlocked before configuration changes; firmware failing to unlock PPS appears as silent peripheral failure.
コンプライアンス情報
RoHS and REACH compliant per Microchip product page. -V temperature grade supports automotive-grade applications but is not formally AEC-Q100 qualified; refer to Microchip's automotive-grade part numbers for that certification.
