PIC32MX230F064B-I/SP Visão geral
What is a PIC32MX microcontroller? The PIC32MX is a family of 32-bit microcontrollers from Microchip based on the MIPS32 M4K architecture. It is a member of the broader microcontroller (MCU) category within microcontrollers and microprocessors, which itself falls under digital integrated circuits and semiconductors. The PIC32MX family bridges 8-bit PIC microcontrollers and 32-bit ARM Cortex-M devices, offering deterministic MIPS performance, generous on-chip memory, and rich peripherals including USB, I2S, PMP graphics interface, and Peripheral Pin Select (PPS) for flexible signal routing.
Key differentiating features of the PIC32MX230F064B-I/SP include Peripheral Pin Select (PPS) for remappable digital I/O, two I2S/SPI modules for codec and serial communication, a Parallel Master Port (PMP) for graphics and external memory interfacing, mTouch capacitive touch support, and a 1 ns resolution Input Capture module for high-precision time measurement. The 28-SPDIP package is pin-through-hole, ideal for prototyping, hobbyist designs, and legacy equipment requiring a DIP footprint.
Technically, the device offers five 16-bit general-purpose timers, a 10-bit ADC with up to 1 Msps conversion rate, and CIP (Core Independent Peripherals) that offload tasks from the CPU. The instruction set is a superset of the 16-bit PIC24/dsPIC instruction set, providing familiar development for legacy PIC developers while delivering 32-bit throughput.
Typical applications for this MCU include low-cost 32-bit control boards, capacitive touch user interfaces, audio playback with I2S codecs, USB device peripherals, and prototyping on breadboards where the DIP package simplifies rework. It is also well suited for industrial sensor aggregation and small graphics interfaces using the PMP.
When designing with the PIC32MX230F064B-I/SP, ensure your programmer/debugger (such as MPLAB PICkit 4 or ICD 4) supports the PGECx/PGEDx ICSP pins on the 28-SPDIP. For high-frequency or noise-sensitive analog designs, route VDD/VSS pairs with decoupling close to the pins and consider the brown-out reset thresholds for battery-powered designs.

Aplicações típicas
PIC32MX230F064B-I/SP é adequado para 7 aplicaçãos: USB Device Peripherals, Audio Playback with I2S Codecs, Capacitive Touch User Interfaces, Graphics Interfaces via PMP, Industrial Sensor Aggregation, Educational and Hobbyist Prototyping, Precision Time Measurement.
USB Device Peripherals
The PIC32MX230F064B-I/SP is well matched to USB 2.0 full-speed device applications thanks to its integrated USB 2.0 full-speed transceiver and 16 KB of SRAM. The MCU runs the Microchip Harmony USB device stack or MLA USB stack at 40 MHz CPU, providing up to 64 KB Flash for HID, CDC, MSD, or custom vendor class firmware. Its 28-SPDIP through-hole package is ideal for prototypes and low-volume industrial USB products where rework-friendly soldering is preferred over QFN. Compared to a discrete USB interface chip + 8-bit MCU, the integrated USB peripheral reduces BOM cost and PCB area.
Recomendado
Audio Playback with I2S Codecs
The PIC32MX230F064B-I/SP supports two I2S modules for interfacing with external audio DACs and ADCs, making it suitable for low-cost audio playback devices and basic audio recorders. Its 64 KB Flash stores modest WAV/ADPCM audio decoders, and 16 KB SRAM accommodates short audio buffers. The 40 MHz MIPS32 M4K core provides adequate processing throughput for sample-rate conversion and simple DSP effects. Industrial temperature grade (-40C to +85C) supports automotive and industrial audio installations where the SPDIP through-hole footprint simplifies field serviceability.
Recomendado
Capacitive Touch User Interfaces
The PIC32MX230F064B-I/SP supports Microchip's mTouch capacitive touch sensing library, enabling touch buttons, sliders, and proximity sensors using standard GPIO pins through the integrated Charge Time Measurement Unit (CTMU). Its 40 MHz core runs the touch decoding algorithm with sub-1 ms response time, and 16 KB SRAM accommodates small UI state machines. The 28-SPDIP package suits through-hole industrial control panels where mechanical rigidity and ease of lead-forming are valued. Designers can drive up to 10-15 touch electrodes via Peripheral Pin Select.
Recomendado
Graphics Interfaces via PMP
The PIC32MX230F064B-I/SP integrates a Parallel Master Port (PMP) for driving small graphical LCDs, OLEDs, and external memory-mapped peripherals. The PMP supports 8-bit and 16-bit parallel data with dedicated address lines, enabling direct interfacing with common graphics controllers without an external bus bridge. Combined with 64 KB Flash for page rendering tables and 16 KB SRAM for framebuffer tiles, the MCU drives small mono or color TFT displays up to QVGA resolution at modest refresh rates. Industrial grade suits HMI panels and instrumentation displays.
Recomendado
Industrial Sensor Aggregation
The PIC32MX230F064B-I/SP is suitable as a sensor hub for aggregating analog and digital sensor data via its 10-bit ADC at up to 1 Msps, UART, I2C, and SPI peripherals. The 32-bit MIPS32 M4K core performs sensor fusion and filtering in real time, while 64 KB Flash accommodates Modbus, CAN, or proprietary protocols via the ECAN module where supported. The -40C to +85C industrial temperature range and 28-SPDIP package suit factory-floor PLC input modules and remote telemetry units where through-hole components improve reliability under vibration.
Recomendado
Educational and Hobbyist Prototyping
The PIC32MX230F064B-I/SP's 28-SPDIP through-hole package makes it ideal for breadboard-friendly learning kits, university microcontroller courses, and hobbyist projects where the MCU must be inserted and removed repeatedly without soldering. The 40 MHz 32-bit MIPS32 M4K core gives students exposure to real-world RISC architecture, while the rich peripheral set (USB, I2S, PMP, ADC, timers) allows a single chip to support a wide curriculum range. Microchip's MPLAB X IDE, XC32 compiler, and Harmony framework provide a complete free toolchain for non-commercial use.
Recomendado
Precision Time Measurement
The PIC32MX230F064B-I/SP's 1 ns Input Capture module enables high-resolution time measurement for ultrasonic distance sensing, pulse-width measurement, motor control feedback, and event timing. Combined with five 16-bit general-purpose timers in a configurable cascade arrangement, the MCU can measure time intervals up to several seconds with sub-microsecond resolution. The 28-SPDIP industrial-grade package suits bench-test instruments, laboratory timers, and field-portable data loggers where mechanical robustness of the through-hole leads is valued over SMT density.

Notas de projeto
The 28-SPDIP through-hole footprint requires standard 0.100 inch (2.54 mm) row spacing pads with through-hole plating. Place one 100 nF decoupling capacitor as close as possible to each VDD pin (pins 7 and 19) and one 10 uF bulk capacitor near the MCU supply entry. Keep crystal traces short and route VSS/VSS pairs with a low-impedance ground pour. For USB applications, the D+/D- traces must be 90 ohm differential impedance-matched and length-matched within 150 mil.
Do not confuse the ICSP pins PGEC1/PGED1 (pins 5/4) with PGEC2/PGED2 (pins 12/13). Either pair can be used for in-circuit programming but the pair must be used together. For new designs, use PGEC1/PGED1 for compatibility with PICkit 3/4 default pinout. The MCLR pin (pin 1) requires a 10 kohm pull-up to VDD for normal operation; do not leave it floating or the MCU will reset intermittently. PGECx/PGEDx must be tri-stated in firmware during runtime to avoid contention.
The PIC32MX230F064B-I/SP typical operating current is below 0.5 mA/MHz at 3.3V, but USB active mode and ADC sampling can increase peak current to 25 mA. For USB bus-powered designs, ensure the upstream VBUS regulator can source at least 100 mA. The on-chip voltage regulator (VCORE) requires a 10 uF + 100 nF decoupling network on the VCAP pin (not brought out to SPDIP, internal). Brown-out reset (BOR) must be configured for the application's minimum VDD to avoid code execution at unsafe voltages.
