DATA SHEET  
MOS INTEGRATED CIRCUIT  
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, µPD78F4046Note, 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.  
µPD784046 Subseries User’s Manual - Hardware : U11515E  
78K/IV Series User’s Manual - Instruction  
: U10905E

In this document, in addition to the µPD784044(A) and µPD784046(A), the µPD784044(A1), 784044(A2)  
784046(A1), and 784046(A2) are also explained. However, unless otherwise specified, the µPD784046(A) is  
treated as the representative model throughout this document.  
The information in this document is subject to change without notice.
