8-bit Microcontrollers AVR® DB Family of Microcontrollers Summary Microchip’s AVR® DB family brings unprecedented analog capability and real-time control functionality to the popular and powerful AVR core. The AVR DB combines integrated level shifters and three highly configurable op amps with the latest Core Independent Peripherals (CIP) to create a device that not only excels as a standalone processor, but is also a perfect companion MCU in designs with multiple power domains. Coming in 28- to 64-pin packages, with up to 128 KB Flash and operating at up 24 MHz across the full supply voltage range of 1.8V to 5.5V the new AVR DB MCUs are ready to meet the needs of a diverse range of applications. Designed for Demanding Analog Applications Intelligent analog peripherals, like 12-bit differential ADC, op amps, Zero-Cross Detect (ZCD), 10-bit DAC and Multi Voltage I/O make the AVR DB family ideal for analog signal conditioning, interfacing sensors and IoT end nodes. The family uses the latest Core Independent Peripherals with lowpower features and 5V operation for increased noise immunity in harsh environments. Multi Voltage I/O (MVIO) The AVR DB includes a unique MVIO option on PORT C. This means that Port C can be interfaced to a different voltage than the rest of the device. This second voltage can be either higher or lower than the main Vdd and level shifting will be completely transparent for the user. This allows seamless bi-directional communication with devices or modules running on a different voltage domain without using external level shifters, saving cost and board space. www.microchip.com/8bit Operational Amplifiers (OPAMP) The AVR DB includes 3 highly configurable operational amplifiers that are perfect for analog signal conditioning. Each op amp has its own optional feedback resistor network allowing a wide range of configurations, many without the need for external components. Inverting and non-inverting amplifiers, filters and instrumentation amplifiers can easily be configured without writing code, by using Microchip’s graphical code building tools MPLAB® Code Configurator (MCC) and Atmel START code builder. The op amps are also supported by MPLAB Mindi™ Analog Simulator which allow full analog simulation of the operation and performance of the analog signal conditioning configuration. Functional Safety The AVR-DB family is recommended for safety critical applications targeting both industrial and automotive products (IEC 61508 and ISO 26262). Necessary documentation such as FMEDA report and Safety Manual can be provided on request. Safety certified development tools are also available for this product. Please contact your local Microchip sales office or your distributor for more information. High-Performance Analog • • • • • • • • • The 12-bit differential Analog-to-Digital Converter (ADC) with conversion speeds of 130 ksps provides accurate and timely analog signal acquisition. Triggering signals and notifications can be transmitted to other peripherals without CPU intervention, enabling robust and deterministic response to system events. The 10-bit DAC output can either be available on an external pin or it can be used to generate an adjustable reference voltage for the Analog Comparator (AC). The AVR-DA features up to three ACs, each having a dedicated DAC reference. 16-bit Real-Time Clock and Periodic Interrupt Timer Configurable Custom Logic (CCL) peripheral Up to 10-channel Peripheral Event System Configurable, internally generated Reference Voltage USART/SPI/dual-mode TWI Available with up to 54 I/O Available in 28-, 32-, 48- and 64-pin packages 1.8V to 5.5V operating voltage range –40˚ to +125˚C operating temperature range Get Started Now All AVR MCUs are fully supported by our comprehensive development ecosystem, which includes MPLAB X Integrated Development Environment (IDE) and Studio—our free IDEs with built-in GCC compiler, and our powerful MPLAB Code Configurator and Atmel START code configuration tools generating factory-validated C-code to help you get your design started correctly.
