Overview

The PIC32MX250F128B is a high-performance 32-bit microcontroller featuring a MIPS32 M4K core operating at up to 50MHz. This device stands out in the PIC32MX family by integrating a Full-Speed USB 2.0 OTG controller and 32KB of SRAM in a compact 28-pin package, making it ideal for space-constrained embedded connectivity applications.

Why Choose This Part

This MCU offers significant I/O flexibility with 5V-tolerant pins and a Parallel Master Port for efficient communication with external displays or memory. The inclusion of hardware DSP instructions and a 4-channel DMA controller allows for high-throughput data handling without overtaxing the CPU.

Applications

USB Peripheral Design
Utilizing the integrated USB OTG controller to create custom HID devices, CDC virtual COM ports, or mass storage class peripherals.
Digital Audio Processing
Leveraging the I2S interface and DSP instructions for basic audio streaming, filtering, and processing tasks.
Industrial Serial Gateways
Acts as a bridge between legacy UART/SPI/I2C equipment and modern USB-enabled industrial control systems.
User Interface Controllers
Driving small displays and managing capacitive touch inputs using the Parallel Master Port (PMP) and integrated ADC.
