ATTINY861A-SU Datasheet PDF - Microchip

The ATTINY861A-SU is a 8-bit high-performance picoPower AVR RISC-based Microcontroller combines 8kB flash memory, 512B EEPROM, 512B SRAM, 16 general purpose I/O lines, 32 general purpose working registers, an 8-bit timer/counter with compare modes, an 8-bit high speed timer/counter, a universal serial interface (USI), internal and external Interrupts, an 11-channel 10-bit A/D converter, programmable watchdog timer with internal oscillator and four software selectable power saving modes. The device operates between 1.8 to 5.5V. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.
