MCHPPIC32MX230F256B-I/SP
Overview
The PIC32MX230F256B-I/SP is a 32-bit MIPS32 M4K-based microcontroller featuring a high-density 256KB Flash and 16KB RAM in a through-hole 28-pin SPDIP package. It operates at 40MHz and integrates a full-speed USB 2.0 OTG controller along with standard serial interfaces. This specific variant is a rare example of a high-performance 32-bit MCU available in a breadboard-friendly DIP format.
Why Choose This Part
The primary advantage is the 28-pin SPDIP package, allowing 32-bit performance on a breadboard or through-hole PCB. It includes 5V-tolerant I/O pins, which simplifies interfacing with legacy 5V digital logic. The integrated USB 2.0 OTG and 4-channel DMA controller provide high-throughput data capabilities typically found in much larger pin-count devices.
Applications
Getting Started
Development is primarily done using the Microchip MPLAB X IDE and the XC32 compiler. For hardware debugging and programming, a PICkit 4 or MPLAB Snap is required to interface with the 2-wire ICSP pins. Engineers often use a 3.3V LDO and a 10uF ceramic capacitor on the VCAP pin for internal regulator stability.
