DATA SHEET
MOS INTEGRATED CIRCUIT
µPD784035(A), 784036(A)
16/8-BIT SINGLE-CHIP MICROCONTROLLER
The µPD784036(A) is a product of the µPD784038 sub-series in the 78K/IV series. A stricter quality assurance
program applies to the µPD784036(A) than the µPD784036 (standard product). In terms of the NEC quality, the
µPD784036(A) is classified as the special grade.
The µPD784036(A) contains various peripheral hardware such as ROM, RAM, I/O ports, 8-bit resolution A/D and
D/A converters, timers, serial interface, and interrupt functions, as well as a high-speed, high-performance CPU.
In addition, the µPD78P4038(A) (one-time PROM or EPROM product), which can be operated within the same
power supply voltage ranges as masked-ROM products, and development tools are supported.
For specific functions and other detailed information, consult the following user’s manual.
This manual is required reading for design work.
