The Microchip ATTINY826-XUR is an 8-bit AVR MCU from the tinyAVR® 2 family, built around a 20 MHz core with 8 KB Flash program memory and 1 KB SRAM.
The I²C, SPI, and UART/USART serial interfaces cover the common sensor and display buses used in embedded control.
Housed in a 20-SSOP (0.209" body width, 5.30 mm wide) surface-mount package.
It runs at 20 MHz with 8 KB Flash, 1 KB SRAM, and 128 bytes of EEPROM. The 8 KB Flash is typical for small-footprint control firmware — enough for sensor polling, simple communication stacks, and PWM generation.
Yes, it includes an internal oscillator, so no external crystal is needed for most applications. This saves board space and two I/O pins that would otherwise be tied to the crystal circuit.
