Welcome
to Hitachi's 16-Bit microcontroller family H8/300H.
H8/300H has enjoyed tremendous success since its introduction in 1993 as a successor to
Hitachi's equally successful H8/500 family. Dataquest has found Hitachi's 16-Bit
microcontrollers to be the most successful world-wide as well as in Europe.

At Hitachi Europe we think that this success was driven by our strong commitment to be a
leading force in the microcontroller marketplace and our belief that we must listen to our
customer's requirements and then meet these. As H8/300H is the result of combining many
years of experience of Hitachi with the experience of our customers, H8/300H is an excellent
example where this policy has worked for our customers and Hitachi.
The European Electronics Industry demands full service and support.
At Hitachi, we responded by setting up a European engineering and tool design subsidiary 12
years ago: Hitachi Microsystems Europe (HMSE) based in Maidenhead (UK).
HMSE provides our customers with locally designed and supported tools ranging from
low cost
evaluation boards
to fully featured
real time emulators
based on IBM-compatible PC's at a
very competitive price. Software ranges from Assembler, an ANSI
C-Compiler
via a C-level
debugger to HIOS, Hitachi's real time operating system. To speed development HMSE supplies
MakeApp, a tool that sets up peripherals and creates driver routines on the click of a mouse.
HMSE also offers support and engineering resources for customers wishing to use Hitachi's
ASIC capabilities. This also applies to our
µCBIC
program, enabling our customers to select
one of Hitachi's CPU cores and combine it with peripherals from our library and adding
customer specified logic via VHDL or Verilog.
