µPD703003A, 703004A, 703025A
V853TM
32-/16-BIT SINGLE-CHIP MICROCONTROLLERS
The µPD703003A, 703004A, and 703025A are members of the V850 FamilyTM of 32-bit single-chip microcontrollers
designed for real-time control operations. These microcontrollers provide on-chip features including a 32-bit CPU
core, ROM, RAM, an interrupt controller, a real-time pulse unit, a serial interface, an A/D converter, a D/A converter,
and PWM.
Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before
designing.

2.3 Pin I/O Circuits and Recommended Connection of Unused Pins
The input/output circuit type of each pin and recommended connection of unused pins are shown in Table 2-1.
Figure 2-1 illustrates the various circuit types using partially abridged diagrams.
When connecting to VDD or VSS via a resistor, a resistance value in the range of 1 to 10 kΩ is recommended.
