The Microchip ATTINY861V-10MUR is an 8-bit AVR MCU from the ATtiny family, clocked at 10 MHz with 8 KB of Flash program memory, 512 bytes of SRAM, and 512 bytes of EEPROM. The 11-channel 10-bit ADC handles analog sensor inputs directly — think thermistor, photodiode, or potentiometer — without an external converter.
Memory and peripheral fit for small-footprint control
With 8 KB Flash and 512 bytes each of SRAM and EEPROM, this part targets applications where the firmware fits in a few thousand lines of C — simple state machines, pulse counting, I²C or SPI sensor polling via the USI, and PWM dimming.
Lifecycle and supply chain
For BOM planning, this removes the risk of a sudden last-time-buy notice. The part is ROHS3 compliant.
