Microchip Technology AVR® DB 8-Bit Microcontrollers
Microchip Technology AVR® DB 8-Bit Microcontrollers are designed to bring analog signal conditioning, real-time control, and multi-voltage operation to applications including industrial control, home appliances, and Internet of Things (IoT). The AVR DB MCUs operate at up to 24MHz across the full supply voltage range of 1.8V to 5.5V. These devices include 32KB, 64KB, and 128KB Flash variants in 28- to 64-pin package options.
The AVR DB MCUs build 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. The Analog Signal Conditioning (ASC) module includes three on-chip operational amplifiers (OPAMPs), enabling signal conditioning without external components. The Multi-Voltage I/O system allows safe bidirectional communication with systems running at a different voltage. The Event System, Configurable Custom Logic (CCL), along with intelligent analog peripherals makes the AVR DB MCUs well-suited for sensor applications, IoT end nodes, and other applications where signal conditioning or level-shifting is needed.
The Microchip Technology AVR DB MCUs are fully supported by a comprehensive development ecosystem. The free MPLAB® X Integrated
Development Environment (IDE) and Studio includes a built-in GCC compiler. The powerful MPLAB Code Configurator and Atmel START code configuration tools generate factory-validated C-code, enabling quick design.
Functional Safety Ready
The Microchip Technology AVR DB Microcontrollers are recommended for safety-critical applications targeting both industrial and automotive products (IEC 61508 and ISO 26262). Necessary documentation such as the FMEDA report and Safety Manual can be provided by Microchip on request.
