• Manufacturer: Hitachi Semiconductor

Preface
The H8/534 and H8/536 are high-performance single-chip Hitachi-original microcomputers,
featuring a high-speed CPU with 16-bit internal data paths and a full complement of on-chip
supporting modules. They are ideal microcontrollers for a wide variety of medium-scale devices,
including both office and industrial equipment and consumer products.
The CPU has a general-register architecture. Its instruction set is highly orthogonal and is
optimized for fast execution of programs coded in the high-level C language. For further speed,
the existing 10-MHz lineup has been extended to include high-speed versions that operate at
16 MHz. Low-voltage versions that operate at 3 V and 2.7 V have also been developed.
On-chip facilities include large RAM and ROM memories, numerous timers, serial I/O, an A/D
converter, I/O ports, and other functions for compact implementation of high-performance
application systems.
H8/534 and H8/536 are available in both a ZTAT
version* with on-chip PROM, ideal for the
early stages of production or for products with frequently-changing specifications, and a masked-
ROM version suitable for volume production.
This manual gives a hardware description of the H8/534 and H8/536. For details of the instruction
set, refer to the H8/500 Series Programming Manual, which applies to all chips in the H8/500
Series.
