• Manufacturer Part Number: upd70f3402
• Description: 32-/16-bit Single-chip Microcontroller With Can Interface
• Manufacturer: Renesas Electronics Corporation.

The CPU of the V850E/RS1, which is based on RISC architecture, executes almost all instructions
in one clock cycle due to its five-stage pipeline control.

Instruction set
- Upwardly compatible with V850 CPU
- Multiplication/division instruction
- Saturated calculation instructions (with overflow/underflow detection function)
- 32-bit shift instructions: 1 clock
- Non blocking Load/store instruction with long/short format
- Multiplication can be performed in 1 or 2 clocks due to on-chip hardware multiplier:
- Four types of bit manipulation instructions:
- 16 bits × 16 bits → 32 bits
- 32 bits × 32 bits → 32 bits or 64 bits in one clock cycle.
