Designed for modern, space-constrained, and power-sensitive applications, this MCU packs a significant punch with its robust feature set, making it an ideal choice for a wide array of embedded projects.

Key Features of the ATTINY816-MBT-VAO

At its core, the ATTINY816 is built around the high-performance AVR® CPU with hardware multiplier, enabling efficient processing for complex tasks. A standout feature is its impressive memory configuration, offering 8 KB of Flash, 512 Bytes of EEPROM, and 512 Bytes of SRAM.

One of the most significant advantages of this microcontroller is its rich set of integrated peripherals. It includes:

Event System (EVSYS): This allows peripherals to communicate and trigger actions independently of the CPU, drastically reducing power consumption and enabling ultra-responsive real-time control.

12-bit Differential ADC with Computation (ADC0): This advanced ADC can perform analog filtering and oversampling in hardware, offloading these tasks from the CPU and providing more accurate results.

Three Configurable Custom Logic (CCL) blocks: These allow for the creation of simple logic functions without software intervention, further enhancing real-time performance and design flexibility.

Three 16-bit Timer/Counters (TCA, TCB, TCD): These are crucial for waveform generation, motor control, and precise timing operations.

Serial Communication Interfaces: It is equipped with USART, SPI, and I2C, providing seamless connectivity with a vast ecosystem of sensors, displays, and other peripheral devices.

Low-Power Operation: The device supports multiple sleep modes and can operate down to 1.8V, making it perfect for battery-powered applications.

The -MBT-VAO suffix specifically denotes a 20-pin VQFN package, which is compact and suitable for automated assembly processes in high-volume production.
