PIC32MX230F064BT-V/SS Overview
An MCU (Microcontroller Unit) is a single-chip computer integrating a CPU core, program memory (Flash), working memory (RAM), and peripheral interfaces. The PIC32MX family sits in the hierarchy as follows: 32-bit MCU -> MIPS M4K architecture -> PIC32 family -> Microchip's mid-range performance tier with USB and mTouch support, designed for cost-sensitive embedded applications requiring more processing power than 8/16-bit MCUs.
Key features include Peripheral Pin Select (PPS) for flexible I/O mapping, Parallel Master Port (PMP) for graphics interfaces, two I2S/SPI modules for codec and serial communications, on-chip temperature measurement, and mTouch capacitive touch button/slider support. The device supports multiple low-power modes for battery-powered applications and integrates a 5-bit comparators and Real-Time Clock Calendar (RTCC).
The PIC32MX230 architecture uses a 5-stage pipeline MIPS32 M4K core with single-cycle multiply and hardware divider. DMA with four channels and automatic data size detection reduces CPU load for data movement. Separate PLLs for CPU and USB clocks provide flexibility, and the USB 2.0 full-speed On-The-Go (OTG) interface enables both host and device roles without an external PHY.
Typical applications include consumer electronics with USB connectivity, industrial control panels with touch interfaces, low-cost graphics displays via PMP, sensor hubs, and battery-powered IoT edge nodes. The mTouch peripheral makes it well-suited for appliance front panels and human-machine interface (HMI) designs.
When designing with the PIC32MX230, observe the 2.3V-3.6V supply range and provide adequate decoupling (100nF plus 10uF bulk) near the VDD pins. The -V suffix denotes the -40C to +105C industrial-grade temperature range suitable for harsh environments.

Typical Applications
PIC32MX230F064BT-V/SS is suitable for 6 applications: USB HID Peripherals and HID Devices, Industrial Control Panels with Touch HMI, Battery-Powered IoT Edge Sensor Hubs, Consumer Audio with I2S Codec Interface, Small Graphical LCD/Segment Display Controllers, USB Barcode/RFID Reader Heads.
USB HID Peripherals and HID Devices
The PIC32MX230F064BT-V/SS suits USB Human Interface Devices such as custom keyboards, mice, game controllers, and HID-class industrial control surfaces thanks to its integrated USB 2.0 Full-Speed OTG controller with separate USB PLL. The 64 KB Flash holds the USB stack, HID report descriptors, and application logic, while 16 KB RAM accommodates USB buffers and HID report data structures. The 40 MHz/66 DMIPS MIPS32 M4K core runs the Microchip Harmony USB stack with ample headroom. PPS reassigns peripherals to free GPIO, easing PCB routing of the USB D+/D- pair on pins 23/24.
Recommended
Industrial Control Panels with Touch HMI
The PIC32MX230F064BT-V/SS is well matched for industrial control panels with mTouch capacitive buttons and sliders. The integrated charge-time measurement unit (CTMU) supports capacitive touch sensing without external components, while the Parallel Master Port (PMP) drives small graphical LCDs for menu and status display. The -40 C to +105 C industrial temperature grade handles factory floor thermal stress. The 10-bit ADC and three comparators handle analog sensor inputs, while the 40 MHz core runs UI logic, debounce, and communication stacks (Modbus, CAN, USB) simultaneously.
Recommended
Battery-Powered IoT Edge Sensor Hubs
The PIC32MX230F064BT-V/SS serves low-power IoT sensor hubs that aggregate analog and digital sensor data and forward it over USB or UART. Multiple low-power modes (Sleep, Idle, Deep Sleep with RTCC wake) reduce quiescent current below 1 uA when idle, ideal for battery-backed installations. The 16 KB RAM buffers sensor history, while the 64 KB Flash stores application code plus a small MQTT or proprietary stack. The two I2C and two SPI/I2S modules connect temperature, humidity, accelerometer, and audio sensors concurrently with PPS-reassignable pin mapping for flexible PCB layouts.
Recommended
Consumer Audio with I2S Codec Interface
The PIC32MX230F064BT-V/SS integrates two SPI/I2S modules, enabling direct connection to audio codecs such as the Microchip/Wolfson WM8904 or AKM AK4556 for stereo audio playback and record paths. The 40 MHz MIPS32 M4K core performs USB audio class enumeration plus sample-rate conversion at standard 48 kHz with negligible CPU load. The 16 KB RAM holds stereo audio buffers, while the RTCC timestamps recordings. The -40 C to +105 C industrial range covers in-vehicle and outdoor audio installations including intercoms, marine audio, and PA accessories.
Recommended
Small Graphical LCD/Segment Display Controllers
The PIC32MX230F064BT-V/SS drives small graphical TFT or monochrome LCD panels through the Parallel Master Port (PMP), supporting 8-bit and 16-bit data widths and dedicated control signals (RD, WR, RS, CS). Combined with the 64 KB Flash storing frame buffers and font tables, plus 16 KB RAM for partial-screen updates, the MCU can refresh small color QVGA displays at modest frame rates for menus and dashboards. The PMP timing is configured in software, enabling adaptation to a wide range of display controllers including ILI9341, ST7735, and SSD1963.
Recommended
USB Barcode/RFID Reader Heads
The PIC32MX230F064BT-V/SS powers USB-attached barcode scanners and RFID readers using the integrated USB 2.0 Full-Speed OTG with HID or CDC profiles. The 10-bit ADC digitizes analog sensor outputs from CCD or CMOS image sensors at modest frame rates, while the two UART/I2C channels connect to RFID modules and external EEPROM. The RTCC timestamps scans for audit logging, and the 64 KB Flash stores symbology decoders for Code 128, QR, and Data Matrix. PPS allows the USB pins and peripheral functions to be remapped, simplifying RF-sensitive PCB layouts.

Key Differentiators
- Integrated USB 2.0 Full-Speed OTG with separate USB PLL (vs PIC32MX130F064BT-V/SS)
- Industrial -V temperature range up to +105 C (vs PIC32MX230F064BT-I/SS)
- Compact 28-SSOP form factor with 5.30 mm body width (vs PIC32MX230F064BT-V/SO)
- mTouch capacitive touch and PMP graphics integrated (vs PIC32MX130F064BT-V/SS)
Design Notes
Decouple VDD (pin 13) and AVDD (pin 7) with a 100 nF ceramic capacitor placed within 5 mm of each supply pin, plus a shared 10 uF bulk tantalum or ceramic capacitor on the board-level 3.3 V rail. The PIC32MX230 has separate analog and digital supplies; connect AVSS to VSS at a single point near the MCU to avoid ground loops in ADC measurements. For USB designs, keep the VBUS sense line clean and add a 4.7 uF capacitor on the VBUS pin if used as a power source.
Route the USB D+ (pin 23) and D- (pin 24) pair as a 90-ohm differential trace with matched lengths and continuous ground reference, kept under 50 mm total length. Place the USB series ferrite bead and ESD protection (such as USBLC6-2SC6) within 10 mm of the connector. The 12 MHz crystal or external oscillator traces to OSC1/OSC2 must be short and guarded by a ground ring to minimize EMI. With Peripheral Pin Select, route high-speed peripherals (I2S, SPI) on adjacent GPIO banks to simplify the layout.
Estimated: MCLR (pin 1) must have a 10 kohm pull-up to VDD and a 100 nF capacitor to ground for proper reset; omitting the cap or using a weak pull-up can cause intermittent failures in noisy environments. Do not exceed 3.6 V on any I/O; the PIC32MX230 is NOT 5 V tolerant and direct connection to 5 V logic will damage the part. For ICSP programming, reserve pins RB0 and RB1 for PGED1/PGEC1 and avoid reassigning them via PPS in production firmware unless a dedicated programmer header is provided.
The PIC32MX230F064BT-V/SS SSOP package has a typical theta-JA of 80 C/W without copper cooling. Estimated: at maximum CPU activity (40 MHz, all peripherals active), the on-chip power dissipation is roughly 60 mW, producing a junction temperature rise of about 4.8 C above ambient - well within the 105 C limit. In enclosed industrial environments, however, ensure that ambient plus self-heating stays below 95 C to provide margin for transients during USB enumeration bursts.
Compliance Information
RoHS and REACH compliant per Microchip product page. Not AEC-Q100 qualified; the -V temperature grade is industrial (-40 C to +105 C) but not automotive-grade. For AEC-Q100 qualified Microchip 32-bit MCUs consider the PIC32MX SAM-based automotive variants.
