DESCRIPTION

The µPD784046(A) is a model in the µPD784046 subseries within the 78K/IV series. A stricter quality assurance program applies µPD784046(A) compared to the µPD784046 (standard model). (In terms of NEC’s quality grading, this is a ”special” grade product.)

The µPD784046(A) is provided with many peripheral hardware functions such as ROM, RAM, I/O port, 10-bit resolution A/D converter, timer, serial interface, and interrupt functions, in addition to a high-speed, high-performance CPU.

The µPD784046(A) is under development.

Moreover, a flash memory model, µPD78F4046Note, that can operate on the same supply voltage as the mask ROM model, and many development tools are under development.
