4. Operating Configuration and Startup
Procedure
4.1 Standalone operation (S5U1C6F632T1)
With the USB-Serial on Board Writer (S5U1C88000W4) connected, the S5U1C6F632T1 can write programs/data to the internal
flash EEPROM of the S1C6F632 mounted on the S5U1C6F632T1 board. Once a program/data is written, the board can run from a
coin cell for standalone operations. The corresponding connection configurations and startup procedures are described below.
1)
Connecting the USB-Serial on Board Writer
Connect the USB-Serial on Board Writer (S5U1C88000W4) to the CN1 connector on the S5U1C6F632T1 board.
Figure 4.1.1 Connecting the USB-Serial on Board Writer
Caution!
Carefully check the position of Pin 1 in the CN1 connector when connecting. The connector lacks a safeguard to prevent
reversed connections.
2)
Selecting the power supply
Set the power supply input selector switch correctly. When using a coin cell, set the jumper switch to “B.” When using an
external power supply, set the switch to “E.” For more information, refer to “2. Component Names and Functions.”
Caution!
When writing programs/data to the flash memory, use an external stabilized power supply, if at all possible. While it is
possible to write programs/data to the flash memory by using the coin cell as the power source, this may result in write errors
if the voltage of the coin cell drops below required levels.
3)
Writing programs/data using the USB-Serial on Board Writer
Write programs/data to the flash EEPROM by referring to Appendix B “PROM Programming” in the
S1C6F632 Technical
Manual
.
4) Operation
After writing programs/data, turn off the power to the board, disconnect the USB-Serial on Board Writer, then turn on power
once again. When an external power supply is used to write programs/data and the coin cell is used for board operations,
switch the power supply input selector from “E” to “B.”
