− | + | The '''Hitachi HMCS40''' is a [[microprocessor family|family]] of [[4-bit architecture|4-bit]] [[microcontroller]]s developed by [[Hitachi]]. Two types of each component were manufactured, one using [[PMOS logic]] for low cost and another using [[CMOS]] where lower power was more desired than cost. | |
