16 MHz AVR core with 125°C ceiling
The Microchip ATTINY1606-SF is an 8-bit AVR MCU from the tinyAVR™ 0 series, which carries a Functional Safety (FuSa) designation. It runs at 16 MHz with an internal oscillator, eliminating the external crystal for many designs. The 16 KB Flash program memory, 1 KB SRAM, and 256 bytes of EEPROM provide enough headroom for small control loops, sensor fusion, or communication stacks using I²C, SPI, or UART/USART.
