Microchip's AVR DD family builds on the low-power performance of the AVR architecture, with an excellent selection of Core Independent Peripherals (CIPs) and a fully loaded smart analog portfolio, giving users the freedom to innovate their designs. With its comprehensive feature set, including multi-voltage input/output (MVIO), the AVR DD series is ideal for complex applications or as a companion microcontroller (MCU) in complex designs with multiple power domains.
This family of MCUs utilizes on-board CIP and 5 V run modes to improve noise immunity, while also reducing system latency through the use of a robust event system (EVSYS) and configurable custom logic (CCL) peripherals. The MVIOs of the AVR DD series allow true level-shifting bidirectional communication with devices on different power domains, eliminating the need for level shifters. The flexibility of this series makes it ideal for real-time control functions in industrial control, home appliances, automotive, Internet of Things (IoT) and other applications. The AVR DB MCU is an excellent choice for signal conditioning functions, with three on-chip operational amplifiers (op amps). Microchip's AVR DA MCUs are an excellent choice for low-latency control applications and capacitive touch user interfaces.
Microchip recommends the AVR DD family for safety-critical applications for industrial and automotive products (IEC 61508 and ISO 26262). They also offer the MPLAB® XC8 Functional Safety Compiler License, a TÜV SÜD certified compiler package supporting 8-bit PIC and AVR MCUs. Documents such as FMEDA reports and safety manuals are available upon request.
