The Hitachi HD35404 was a 4-bit microprocessor first produced first quarter of 1975 by Hitachi.[1] The HMCS-4 used pMOS technology and was architecturally compatible with the Intel 4004. The chip came in 16-pin DIP packages. The HD35404 was part of the Hitachi HMCS-4, an Intel MCS-4 clone. The HD35404 was the first microprocessor produced by Hitachi which paved their way into the microprocessor market.
