MCHPAVR32DU28 microcontroller

Overview

The AVR32DU28-I/STX is a Microchip AVR DU-series 8-bit microcontroller with 32 KB of flash, 4 KB of SRAM, and an internal core clock up to 24 MHz. It adds integrated USB, a 10-bit ADC, and common serial interfaces like UART, SPI, and TWI, making it a compact general-purpose MCU for embedded control and connectivity tasks.

Why Choose This Part

This part combines a modest memory footprint with useful on-chip peripherals, so it can handle practical embedded tasks without adding much external logic. Integrated USB and standard serial interfaces reduce BOM complexity and simplify board design. The AVR architecture is familiar to many embedded engineers, which can shorten bring-up time for straightforward control applications.

Applications

Getting Started

Start with Microchip's AVR DU-family development ecosystem, using MPLAB X IDE and the AVR-GCC toolchain. For hardware bring-up, use a compatible Microchip development board or a custom PCB with the recommended programming/debug interface for the AVR DU family. Verify clocking, USB power and signal routing, and ADC reference choices early in the design to avoid integration issues.
