描述 Description

Overview
The H8/3004 and H8/3005 are 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.
The on-chip system supporting functions include RAM, a 16-bit integrated timer unit (ITU), a watchdog timer (WDT), a serial communication interface (SCI), an A/D converter, I/O ports, and other facilities.
Two MCU operating modes—modes 1 and 3—offer a choice of address space size.
