µPD703003
V853TM
32/16-BIT SINGLE-CHIP MICROCONTROLLER
The µPD703003 is a member of the V850 FamilyTM of 32-bit single-chip microcontrollers designed for real-time
control operations. This microcontroller provides on-chip features, including a 32-bit CPU core, ROM, RAM, interrupt
controller, real-time pulse unit, a serial interface, an A/D converter, a D/A converter, and PWM signal units.
See the following manuals for a detailed description of this product’s functions. Be sure to use these
manuals as a reference for design.

2.3 I/O Circuits of Pins and Processing of Unused Pins
Table 2-1 lists I/O circuit type of respective pins and processing method (recommended connection method) when
not used. 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.
