ATtiny28L

The ATtiny28 is a low-power CMOS 8-bit Microcontroller based on the AVR RISC archi- tecture. By executing powerful instructions in a single Clock cycle, the ATtiny28 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 the 32 Registers are directly con- nected to the Arithmetic Logic Unit (ALU), allowing two independent Registers to be accessed in one single instruction executed in one Clock cycle. The resulting architec- ture is more code efficient while achieving throughputs up to ten times faster than conventional CISC Microcontrollers By ATMEL Corporation
