Preface
The H8/3048B Group is a series of high-performance microcontrollers that integrate system
supporting functions together with an H8/300H CPU core. In addition, the H8/3048F-ONE is
equipped with an on-chip emulator (E10T)*².
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 emulator (E10T)*² has functions that allow it to emulate directly a microcontroller
mounted on the user board. This makes possible on-board program debugging.
The on-chip supporting functions include ROM, RAM, a 16-bit integrated timer unit (ITU), 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 direct memory access controller
(DMAC), a refresh controller, and other facilities. Of the two SCI channels, one 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 operating modes (modes 1 to 7) are provided, offering a choice of data bus width and
address space size.
With these features, the H8/3048B Group can be used to implement compact, high-performance
systems easily.
Versions with either flash memory (F-ZTAT™*¹) 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 H8/3048B Group hardware. For information on H8/3048 Group
products, please refer to the H8/3048 Group Hardware Manual. For details of the instruction set,
refer to the H8/300H Series Programming Manual.
