− | The '''μCOM-4''' | + | The '''μCOM-4''' line is an [[microprocessor family|extended family]] of [[4-bit architecture|4-bit]] [[microcontroller]]s developed by [[NEC]] in the late 1970s. This family was designed to be low-cost, mass-produced, [[microcontroller]]s for [[electronic cash register|ECRs]], industrial controllers, appliance controllers, games, toys, scientific calculators, and other consumer electronics. The μCOM-4 line is based on the {{nec|μPD751}}, the first Japanese single-chip microprocessor. |
