Atmel ATtiny1634 8-Bit AVR® Microcontroller

Atmel ATtiny1634 8-Bit AVR® Microcontroller

Atmel's ATtiny1634 8-Bit AVR® Microcontroller is based on the AVR® enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATtiny1634 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. The AVR® core combines a rich instruction set with 32 general purpose working registers. All 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in a single instruction, executed in one clock cycle. The resulting architecture is compact and code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.
