In Brief
H8S & CAN derivatives
In this brochure an overview is given as
to why H8S and H8/300H give you the
technical benefits that are demanded by
today’s applications.The purpose is to
give you enough insight into the features
of the H8S and H8/300H family to see
how you can benefit from the
performance, the rich set of peripherals
and the memory options available.To
summarise this:
• High performance CPU with
architecture tailored for high level
language software development
• Industry leading low power, low
voltage options
• Memory line up from 16K to 256K
ROM and 512Byte to 16K RAM,
including many Flash versions up to
256K Flash
•
Very powerful and sophisticated
peripherals designed to reduce CPU
overhead and hence to increase system
performance
• High memory and peripheral
integration to allow single-chip
systems,where previously multi-chip
systems were necessary. Switching
from multi-chip to single-chip will
drastically reduce radiation,board
space requirements and enables the
usage of all pins as ports instead of
using them as busses.
• Full European technical and tool
support provided by Hitachi
Microsystems Europe (HMSE) in
Maidenhead (UK)
There is a strong road map that underlines
Hitachi’s commitment to H8 as an
architecture that will be a dominant player
in the industry for many years to come.
The road map points towards:
• 33MHz at 3.3V H8S devices by the
second half of 2000
• more large memory variants (up to
512K Flash) within year 2000
• high-speed Flash as a standard ROM
technology, as price is decreasing to
fall from OTP levels towards mask
• further decrease in power
consumption by shifting Vcc to 2.2V
and by adding 32kHz subclock
•
future peripherals including 2x
CAN-derivatives,high-current
stepper motor drivers,on-chip
LCDC and much more.As an
