Microchip ATTINY814-SSNR: A Comprehensive Guide to Features and Applications

The Microchip ATTINY814-SSNR stands as a powerful and versatile 8-bit microcontroller within the modern AVR family, engineered to deliver high performance and flexibility for a vast array of embedded control applications. Its integration of advanced peripherals, robust core architecture, and low-power operation makes it an ideal choice for designers seeking to create efficient and sophisticated electronic systems.

At the heart of the ATTINY814-SSNR lies the high-performance AVR® CPU with hardware multiplier, capable of running at speeds up to 20 MHz. This core ensures efficient data processing and rapid execution of control algorithms. A significant architectural advantage is its Core Independent Peripherals (CIPs), which allow tasks to be handled without constant CPU intervention. This dramatically reduces power consumption and frees up the core to manage more complex operations, enhancing overall system responsiveness and efficiency.

The memory configuration is tailored for data-intensive applications, featuring 8 KB of Flash, 512 Bytes of EEPROM, and 1 KB of SRAM. This provides ample space for application code and data storage. A standout feature of this microcontroller is its sophisticated Event System (EVSYS). This allows peripherals to communicate and trigger actions directly amongst themselves, creating a highly responsive and deterministic system architecture that is perfect for real-time control.

Connectivity is a major strength of the ATTINY814-SSNR. It includes a USART with LIN support, an I2C (Two-Wire Interface), and an SPI (Serial Peripheral Interface), offering multiple standardized options for communicating with sensors, other ICs, and host processors. For analog integration, it is equipped with a high-resolution 14-channel 10-bit ADC, a 16-bit Timer/Counter type B (TCB), and multiple 16-bit Timer/Counters type A (TCA). These features are essential for precision sensing, motor control, and power management applications.

Operating across a wide voltage range (1.8V to 5.5V) and featuring multiple power-down sleep modes, the device is exceptionally well-suited for battery-powered and low-power applications. From consumer electronics and IoT nodes to industrial automation and automotive subsystems, its low current consumption extends battery life significantly.
