Description
R8C CPU core
• Number of fundamental instructions: 89
• Minimum instruction execution time:
50 ns (f(XIN) = 20 MHz, VCC = 2.7 V to 5.5 V)
200 ns (f(XIN) = 5 MHz, VCC = 1.8 V to 5.5 V)
• Multiplier: 16 bits × 16 bits → 32 bits
• Multiply-accumulate instruction: 16 bits × 16 bits + 32 bits → 32 bits
