• Manufacturer Part Number: HD6432670
• Description: (HD64F267x Series) 16-Bit Microcomputer
• Manufacturer: Hitachi

The H8S/2678 Series and H8S/2678R Series are microcomputers (MCU) made up of the
H8S/2600 CPU employing Hitachi's original architecture as their cores, and the peripheral
functions required to configure a system.
The H8S/2600 CPU has an internal 32-bit configuration, sixteen 16-bit general registers, and a
simple and optimized instruction set for high-speed operation. The H8S/2600 CPU can handle a
16-Mbyte linear address space.
This LSI is equipped with direct memory access controller (DMAC and EXDMAC) and data
transfer controller (DTC) bus masters, ROM and RAM memory, a 16-bit timer pulse unit (TPU), a
programmable pulse generator (PPG), an 8-bit timer (TMR), a watchdog timer (WDT), a serial
communication interface (SCI and IrDA), a 10-bit A/D converter, an 8-bit D/A converter, and I/O
ports as on-chip peripheral modules required for system configuration
A high functionality bus controller is also provided, enabling fast and easy connection of DRAM,
SDRAM, and other kinds of memory.
A single-power flash memory (F-ZTAT
this LSI's ROM. The F-ZTAT version provides flexibility as it can be reprogrammed in no time to
cope with all situations from the early stages of mass production to full-scale mass production.
This is particularly applicable to application devices with specifications that will most probably
change.
This manual describes this LSI's hardware.
