MOS INTEGRATED CIRCUIT
µPD784035, 784036, 784037, 784038
16/8-BIT SINGLE-CHIP MICROCONTROLLER
The µPD784038 is a product of the µPD784038 sub-series in the 78K/IV series. It 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 (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.
