The Atmel AT90S1200 is an 8-bit RISC microcontroller based on the AVR enhanced RISC architecture. It features 1K byte of in-system programmable Flash memory, 64 bytes of SRAM, 15 general purpose I/O lines, 32 general purpose working registers, one 8-bit timer/counter with compare modes, internal and external interrupts, a programmable serial UART and three software selectable power saving modes. It executes powerful instructions in a single clock cycle, enabling it to achieve throughputs approaching 1 MIPS per MHz, allowing the system designer to optimize power consumption versus processing speed.
