Upward Compatibility

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

(memory-to-memory access, one instruction)

• Advanced conditional branching instructions

• Powerful CISC instructions with small code size

CPU Register Set

The CPUs within the H8 family are

designed from the same register set,

allowing complete compatibility.
