Editing nec/μcom-4 (section)

== Families ==
The μCOM-4 was original divided into two separate domains:

===μCOM-42===
The '''{{nec|μCOM-42}}''' was specifically marketed for [[electronic cash register]]s (ECRs), [[Point of Sale]] (POS), and [[electronic scale]] applications. The μCOM-42 chips were specifically designed for controlling 8x4 keyboards, 8-digit displays, and various ECR-type printers. The μCOM-42 had a separate, modified instruction set, compared with the rest of the μCOM-4 families.

===μCOM-43/44/45===
The '''{{nec|μCOM-43}}/{{nec|μCOM-44|44}}/{{nec|μCOM-45|45}}''' was marketed as a general-purpose microcontroller suited for a large array of low-cost consumer and industrial applications. These MCUs shared a common instruction set.

* '''{{nec|μCOM-43}}''' - high-end family of MCUs, offering complete support for the entire [[/isa|μCOM-4 ISA]].
* '''{{nec|μCOM-44}}''' - mid-range family of MCUs, providing a subset of 58 instructions at a reduced cost.
* '''{{nec|μCOM-45}}''' - low-end family of MCUs, providing a subset of 58 instructions and less memory at the cheapest price.
