Overview
The H8/3028 Group comprises microcontrollers (MCUs) that integrate system supporting functions together with an H8/300H CPU core having an original Hitachi architecture.
The H8/300H CPU has a 32-bit internal architecture with sixteen 16-bit general registers, and a concise, optimized instruction set designed for speed. It can address a 16-Mbyte linear address space. Its instruction set is upward-compatible at the object-code level with the H8/300 CPU, enabling easy porting of software from the H8/300 Series.
