This manual describes the hardware features of the V850ES/HF2 single-chip microcontroller, including power supply voltage range, I/O voltage, pin configuration, clock source, and memory mapping.
This manual introduces the NEC V850ES/HF2 32‑bit single‑chip microcontroller, describing its hardware architecture, pin assignments, CPU registers, and on‑chip peripheral functions. It also explains conventions used throughout the document and lists related reference manuals and development tools.
The document includes detailed electrical specifications, recommended handling of unused CMOS pins, ESD protection measures, and power‑on/off sequencing. An appendix provides the complete instruction set list for software developers.

Unused CMOS input pins should be connected to VOP or GND via a resistor, using pull‑up or pull‑down circuitry to fix the input level.
Use anti‑static containers, ground workbenches and operators, keep the environment humid, and avoid insulating materials that build up static electricity.
