5 / 923 page  Rev. 2.00, 09/03, page v of xxx Preface The H8/3028 Group comprises high-performance single-chip microcontrollers that integrate system supporting functions together with an H8/300H CPU core. 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. The on-chip supporting functions include ROM, RAM, 16-bit timers, 8-bit timers, a programmable timing pattern controller (TPC), a watchdog timer (WDT), a serial communication interface (SCI), an A/D converter, a D/A converter, I/O ports, a DMA controller (DMAC), and other facilities. The three-channel SCI has been expanded to support the ISO/IEC7816-3 smart card interface. Functions have also been added to reduce power consumption in battery-powered applications: individual modules can be placed in standby, and the frequency of the system clock supplied to the chip can be divided down under software control. The address space is divided into eight areas. The data bus width and access cycle length can be selected independently in each area, simplifying the connection of different types of memory. Seven MCU operating modes (modes 1 to 7) are provided, offering a choice of data bus width and address space size. With these features, the H8/3028 Group offers easy implementation of compact, high-performance systems. Versions with either flash memory (F-ZTAT *) or mask ROM as the on-chip ROM are available. This enables users to respond quickly and flexibly to changing application specifications from the initial production stage through full-scale volume production. This manual describes the H8/3028 Group hardware. For details of the instruction set, refer to the H8/300H Series Programming Manual.
