Microchip AVR128DB28-I/SO AVR Microcontroller, 128kB RAM, 28-Pin SOIC

The Microchip Microcontrollers feature the well-known AVR CPU, running at up to 24 MHz. It is designed to bring capacitive touch sensing and real-time control functions to applications including industrial control, home appliance products, automotive, and Internet of Things (IoT). It uses the latest Core Independent Peripherals with low-power features and 5V operation for increased noise immunity. The Event System, Configurable Custom Logic (CCL), along with intelligent analog peripherals like 12-bit differential ADC, Zero-Cross Detect (ZCD), DAC together with the ASC and MVIO makes it well suited for sensor applications, IoT end nodes and other applications where signal conditioning or level-shifting is needed.
