H8 MCUs: Fully Upward Compatible
H8 CPUs are all CISC-based (Complex Instruction
Set Computation), developed to allow compatibility up
and down the various H8 series. This makes it easy to
move between the product lines in the H8 family.
The CPUs within the H8 family range from 8-bit,
low-power optimized cores, to full 32-bit high-performance
cores that achieve 1MIPS/MHz.
Benefits of H8 CPU cores include:
• Most instructions execute in one clock cycle
• Built-in hardware MAC (H8S/2600 and H8SX only)
• Fast multipliers and dividers
• Enhanced memory addressing schemes
• Advanced conditional branching instructions
• Powerful CISC instructions with small code size
