H8
General Registers
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
