Overview

The PIC32MX250F128D-I/PT is a 32-bit microcontroller featuring a MIPS32 M4K core operating at up to 50MHz. It integrates 128KB of Flash and 32KB of RAM, providing a balanced memory-to-performance ratio for mid-range embedded applications. This device is particularly noted for its integrated USB 2.0 On-The-Go (OTG) support and specialized hardware for capacitive touch sensing.

Why Choose This Part

The MIPS16e mode significantly reduces firmware footprint, allowing for up to 40 percent smaller code size compared to standard 32-bit instructions. Its hardware-based CTMU simplifies the implementation of capacitive touch without heavy CPU overhead, while the high-speed 1.1 Msps ADC provides precise sensor data acquisition.

Applications

USB Audio Devices
Utilizes the integrated I2S interface and USB OTG support to create high-quality digital audio peripherals.
Capacitive Touch Panels
Leverages the Charge Time Measurement Unit (CTMU) to implement mTouch sensing for buttons, sliders, and wheels.
Consumer Peripherals
Serves as a main controller for USB-connected consumer electronics requiring low-power sleep modes and fast wake-up times.
Embedded Control Systems
Provides reliable performance in industrial environments using its 1.1 Msps ADC and fail-safe clock monitor.
