SH67P54/K54/P53/K53 Evaluation board (EVB)
The SH67P54/K54/P53/K53 EVB is used to evaluate the SH67P54/K54/P53/K53 chip's function for the development of
application program. It contains of a SH67V54 chip to evaluate the functions of SH67P54/K54/P53/K53. The following figure
shows the placement diagram of SH67P54/K54/P53/K53 EVB.

V2.1 2/11
There are two configurations of SH67P54/K54/P53/K53 EVB in application development: ICE mode and stand-alone mode.
In ICE mode, the ICE (motherboard) is connected to the EVB by ICE interface.

(a) ICE mode
In standalone mode, the EVB is no longer connected to the motherboard, but the Flash (or EPROM) must be inserted to the
socket that stored the application program.

The process of program evaluation on SH67P54/K54/P53/K53 EVB
User can use Sino Wealth Rice66 Integrated Development Environment (IDE) to emulate the program and produce the
obj file. Rice66 IDE is a real-time in-circuit emulator program. It provides real-time and transparent emulation support for the
SH6X series 4-bit micro-controller. And integrate assembler can create binary (*.obj) file and the other files.
Use Flash (or EPROM) In standalone mode
Rice66 IDE is built-in with an object file depart function. The command ”Split object file” can separate the one 16 bits object
file into two 8 bits files, which contain the high and low bytes respectively.
Write the high/low byte obj file to Flash (or EPROM) and insert them to EVB (ROMH and ROML). Then, user can
evaluate the program in standalone mode.

External VCC input for stand alone mode:
J1, J2 -The external power input when the EVB worked in stand-alone mode. The voltage of Vcc must be
5V±5%.
Interface to ICE:
J4, J5 -connect to RICE66 2.0, or connect to RICE66 3.0 with a transition board.
J8 -connect to RICE66 3.0 directly.
Interface to test the EV chip operating current
JP2 - User can test the EV chip current through JP2
Note: In ICE mode, the current value is correct only when the RICE66 runs in external clock from EVB mode. (Select the
“external clock from EVB” in OSC Frequency Config manual.)

Diagnostic LED:
Power LED: The LED will be turned on when the EVB is powered.
HALT LED: The LED will be turned on when the system is in HALT mode.
STOP LED:
The LED will be turned on when the system is in STOP mode.
Oscillator setting:
The SH67P54/K54/P53/K53 EVB supports 2 on board oscillators, one is low frequency oscillator (OSC: 32KHz Crystal or
262KHz RC) and the other is high frequency oscillator (OSCX: 400K –4MHz Ceramic or Internal 4MHz ).

The internal resistors of LCD bias can be selected by software in SH67P54/K54/P53/K53.When large LCD panel is used,
user can set the value of $07 to increase the bias current for better LCD performance. But it will cost more power, User
can also use external parallel connection resistances for complex bias current.
Notes: To avoid somewhat leakage current, it is necessary to set LCD driver to the 1/4 duty before the system enters a
STOP mode.
