A 32-bit RISC microprocessor "V810" that has 5-stage pipeline structure and a 1 Kbyte, direct-mapped instruction cache realizes 2.5 MHz operation at 0.9 V with 2.0 mW power consumption. The supply voltage can be reduced to 0.75 V. To overcome narrow noise margin, all the signals are set to have rail-to-rail swing by pseudo-static circuit technique. The chip is fabricated by a 0.8 µm double metal-layer CMOS process technology to integrate 240,000 transistors on a 7.4 mm7.1 mm die.
