In addition, the AVR DA family of MCUs brings additional value to embedded real-time control systems. The integrated event system enables inter-peripheral communication without involving the CPU. Events are latency free and never lost, providing enhanced real-time performance and predictability for reliable and safe designs. By reducing the time the CPU needs be active, the overall power consumption of the application is reduced.

The configurable custom logic peripheral enables the setup of logical functions internally, eliminating the need for external components, reducing board space and bill of material costs. With the new advanced analog features like the 12-bit differential ADC, the AVR DA family of MCUs can measure small amplitude signals in noisy environments, making them well suited for sensor node applications in harsh environments.
The AVR DA family of MCUs’ high memory density and SRAM-to-flash ratio make it attractive for both wireless and wired connected sensors nodes, as well as other stack-intensive applications.
Development Tools
Microchip’s AVR DA family of MCUs offers several options for software and hardware support. Software support includes Microchip’s MPLAB® X, MPLAB Xpress and Atmel Studio, code configuration tools including MCC and START, and compilers including GCC, XC8 and the IAR Embedded Workbench. A functional safety certified version of the XC8 compiler is available via Microchip’s Functional Safety Ready program. Hardware support is included in debuggers/programmers including MPLAB PICkit4, MPLAB SNAP, Atmel ICE and the AVR128DA48 Curiosity Nano evaluation kit.
