APPENDIX PERIPHERAL CIRCUIT BOARDS FOR S1C63656
A.1.2 S5U1C63658P2
The S5U1C63658P2 board provides the R/f converter function that supports resistive sensors such as a
thermistor and resistive humidity sensors.
The following explains the names and functions of each part of the S5U1C63658P2 board.
(1) R/f converter monitor pins and external part connecting socket (Channel 0)
These monitor pins are used to check the operation of R/f converter channel 0. The socket is used to
connect external resistors and a capacitor for R/f conversion.
Mount resistors and a capacitor on the platform attached with the S5U1C63658P2 and then connect it
to the onboard socket.
(2) R/f converter monitor pins and external part connecting socket (Channel 1)
These monitor pins are used to check the operation of R/f converter channel 1. The socket is used to
connect external resistors and a capacitor for R/f conversion.
Mount resistors and a capacitor on the platform attached with the S5U1C63658P2 and then connect it
to the onboard socket.
