µPD784044(A), 784046(A)
16-BIT SINGLE-CHIP MICROCONTROLLER
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, µPD78F4046^Note, that can operate on the same supply voltage as the mask ROM
model, and many development tools are under development.
Note Use for functional evaluation only.
The functions are described in detail in the following User’s Manuals. Be sure to read these manuals when
designing your system.
