Support for the ATtiny841 within Atmel Studio 6.1 requires a device support package: DOWNLOAD

The high-performance Atmel picoPower 8-bit AVR RISC-based microcontroller combines 4KB ISP flash memory, 512-Byte EEPROM, 128B SRAM, 12 general purpose I/O lines, 32 general purpose working registers, an 8-bit timer/counter with two PWM channels, two 16-bit timer/counters with two PWM channels, internal and external interrupts, an 12-channel 10-bit A/D converter, 2 On-chip analog comparators, 2 full duplex USARTs with Start Frame wake up from power down, master/slave SPI serial interface, slave I2C serial interface, programmable gain stage (1x, 20x, and 100x) for 12 differential ADC channel pairs, programmable watchdog timer with internal oscillator, internal calibrated oscillator, and four software selectable power saving modes. The device operates between 1.7-5.5 volts.

By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.
