Overview
The H8/3217 Series is a series of single-chip microcomputers integrating a CPU core together with a variety of peripheral functions needed in control systems.
The H8/300 CPU is a high-speed processor featuring powerful bit-manipulation instructions, ideally suited for realtime control applications. The on-chip supporting modules include ROM, RAM, four types of timers (16-bit free-running timer, 8-bit timer, PWM timer, and watchdog timer), a serial communication interface, I2C bus interface (option), host interface, and I/O ports.
Note that the H8/3212 and H8/3202 have a subset specification that does not include certain of the on-chip supporting modules.
The H8/3217 Series can operate in single-chip mode or in two expanded modes, depending on the memory requirements of the application. The operating mode is referred to in this manual as the MCU mode (MCU: MicroComputer Unit).
In addition to the mask ROM versions, ZTAT™* versions are available with electrically programmable ROM that can be programmed at the user site.
