The AVR SD series is a cost-effective solution introduced by Microchip for entry-level applications. This series retains the ease of use and low power consumption characteristics of the traditional AVR core while undergoing significant cost optimisation, making it particularly suitable for price-sensitive consumer electronics and simple control applications. The AVR SD series offers flash memory options ranging from 4KB to 32KB, operates at frequencies up to 20MHz, and includes a 12-bit ADC, PWM, and basic communication interfaces (UART/SPI/I²C). Its most notable advantage lies in its ultra-low power design, with a sleep mode current as low as 0.1μA, effectively controlling BOM costs for high-volume applications such as smart toys, remote controls, and small appliance control boards. In practical applications, the AVR SD series has been widely adopted in LED lighting systems, environmental monitoring modules, and electronic training kits.

The AVR DD series represents the perfect combination of small packaging and high integration, making it particularly suitable for space-constrained applications. This series offers small package options ranging from 14 to 32 pins, integrating a wealth of peripheral resources in an extremely small board area, including a 12-bit ADC, analog comparator, multiple PWM outputs, and USART interface. The innovative feature of the AVR DD series is its ‘peripheral interconnect’ functionality, which allows direct interaction between different peripherals without CPU intervention, significantly enhancing real-time response capabilities. The AVR DD series is particularly favoured for smart home sensor nodes and miniature IoT devices, with its compact size and low operating voltage as low as 1.8V making it an ideal choice for battery-powered portable devices.

The AVR DB series is optimised for motor control and power conversion applications, enhancing the standard AVR architecture with dedicated motor control peripherals, including high-resolution PWM (up to 144MHz), window watchdog timers, and hardware overcurrent protection. A notable feature of the AVR DB series is its 5V-rated I/O ports, which offer enhanced interference resistance in industrial environments. The AVR DB series excels in applications such as brushless DC (BLDC) motor drives, digital power conversion, and industrial lighting control, with its hardware-accelerated mathematical operations significantly improving the execution efficiency of closed-loop control algorithms.

The AVR EB series is positioned as a high-performance 8-bit solution, suitable for applications requiring strong processing capabilities while still needing to control costs. This series offers up to 128KB of flash memory and 16KB of SRAM, making it one of the most memory-rich models in the AVR family. The AVR EB series introduces a dual-zone flash memory design, supporting secure wireless firmware updates during application programming (IAP), a feature that makes it highly favoured in IoT edge devices. The AVR EB series' event system and multi-channel DMA controller significantly reduce the CPU load, enabling it to efficiently handle complex tasks such as multi-sensor data fusion, demonstrating unique advantages in applications such as smart home gateways and industrial sensor hubs.

As the new flagship of the AVR family, the AVR EA series represents the pinnacle of 8-bit AVR architecture. While maintaining excellent energy efficiency, this series significantly enhances processing performance and peripheral functionality. Core innovations of the AVR EA series include a hardware multiplier, enhanced analogue front end (up to 14-bit ADC), and advanced encryption engine, enabling it to handle applications with high performance and security requirements. The AVR EA series is rapidly gaining adoption in fields such as medical devices, payment terminals, and industrial communication modules, with its hardware encryption acceleration features particularly suited for applications requiring secure boot and data encryption.

The AVR DU series is an innovative product designed for ultra-low power consumption and autonomous operation. The series adopts Microchip's latest picoPower technology, optimising power consumption to the extreme while maintaining processing capabilities. The most prominent feature of the AVR DU series is its autonomous peripheral system, which allows peripherals such as analogue comparators, ADCs, and timers to operate independently and trigger each other while the CPU is in sleep mode, enabling true ‘set-and-forget’ operation mode. The AVR DU series excels in applications such as energy harvesting devices, long-term deployed wireless sensor nodes, and wearable devices, with its innovative power management architecture extending battery life by several times.
