1 Overview
1.1 System Development Kit content
Thank you for purchasing our product. If you take care on the different
hints in this manual you will have great success in software development
with this microcontroller. Please refer to the documents listed in appendix.
The System Development Kit
contains the following parts:
Evaluation-Board HTEB1
CD-ROM
User manual (this document)
RS232 cable (1.8m, DSub9, male-
female)
4 plastic feet for the HTEB1
Carefully remove the board from the shipping carton. Check first if there
are any damages before power on the evaluation board.
1.2 Hardware description
The Hitachi-Tiny-Eval-Board (HTEB1) is a low cost multifunctional
evaluation board for the Hitachi Tiny H8/3664F microcontroller. It can be
used stand alone for software development and testing or as a simple
target board. You can use the Flash-Download-Tool (FDT) for
programming the target code or work with a debug system (E10T) at the
provided connector. The board allows the designer immediately to start
with the software development before his own final target system is
available.
This eval-kit provides some additional hardware e.g. 8 LED’s, a 2*16
Character LCD, 4 key’s, a PC-AT-keyboard connector, an I2C-connector
and more for hard- and software evaluation. All peripherals are used by
some software application notes. Please refer chapter 3.

1.5 Jumpers and switches
JP1 is used for switching the serial interface from 1:1
to crossed connection. If you connect a 1:1 cable (like
the cable that comes with the kit) use the default
setting. If you connect a crossed cable set the jumper
to alternate setting.
JP3 is used for the LCD-LED backlight. If the jumper is
closed (1-2) the backlight will be ON. Remove the
jumper (=open) if backlight operation is not
necessary.
JP2 is used for I2C interface
JP4 is used as an output for the DAC or for PWM

S_PROG/RUN switches between RUN- and
PROG(PROGRAMMING) mode.
KEY_1 (T1) to KEY_4 (T4) are user keys.
RESET_KEY (T7) is for reset.

Main crystal (Q1) can be changed to another
frequency. Therefore a crystal socket is provided.
Please refer to the microcontroller hardware
documentation for recommended devices. The crystal
type should be a HC49 / HC49U type. Eventually
change the capacitors C6/C7 if necessary. If you
change the crystal frequency take care on possible
changes by flash download tool (see FDT manual).
