8-Bit AVR [r] Microcontroller with 8K bytes In-System Programmable Flash

The AT90S8515 is a low-power CMOS 8-bit microcontroller based on the AVR [r] enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the AT90S8515 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
