AVR® DB Family of Microcontrollers
Microchip's AVR DB family of microcontrollers is designed for demanding analog applications
Microchip Technology's AVR DB family builds upon the low-power performance of the AVR core with a world-class selection of core independent peripherals (CIPs) and a fully loaded intelligent analog portfolio, giving users the freedom to design tomorrow’s solutions today. Featuring three on-chip operational amplifiers (op amps), this family is unparalleled in its signal conditioning capabilities. With its multi-voltage I/O (MVIO), the AVR DB is a perfect companion microcontroller (MCU) in complex designs with multiple power domains.
This family of MCUs leverages on-board CIPs and a 5 V operation mode for increased noise immunity while also reducing system latency by using the powerful event system and configurable custom logic (CCL) peripherals. The AVR DB family’s MVIO allows true level-shifted bidirectional communication with devices on a different power domain. Users can use the AVR DB family for real-time control functions in industrial control, home appliance, automotive, Internet of Things (IoT), and other applications. For low-latency control applications and capacitive touch user interfaces, Microchip's AVR DA MCUs are a great option.
The AVR DB family is recommended for safety-critical applications targeting both industrial and automotive products (IEC 61508 and ISO 26262). It also offers the MPLAB XC8 Functional Safety Compiler License, a TÜV SÜD certified compiler package that supports 8-bit PIC® and AVR microcontrollers. Documents such as FMEDA reports and safety manuals are available on request.
