ATTINY841-MU (MICROCHIP)

The ATTINY841-MU is a 8-bit high-performance picoPower AVR RISC-based Microcontroller combines 8kB ISP flash memory, 512B 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 analogue comparators, 2 full duplex USARTs with Start Frame wake up from power down, master/slave SPI serial interface, slave I?C 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 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.
