2. Circuitry Examples
The following diagrams show examples of a circuit for serial programming when you design peripheral circuit of
MCU.
2.1. M16C/60 (except [2 Power supplies]), M16C/80, M32C/80 (except [2 Power supplies]), R32C/100 (except
[2 Power supplies]) Series, and M16C/24 Group and selecting “Standard serial I/O mode 1 (Clock
synchronous)”
[Circuitry Examples]
Note 1. When stand-alone programming, the power supply of S550-SFWv3 is provided by the user target board
via Vcc pins. Connect the power source of the board to the Vcc terminal directly.
Note 2. Isolate TXD, RXD, SCLK, and BUSY terminals from the MCU peripheral circuit, in case the jumper,
analog switching, three-state, etc. are built in when serial programming. Isolation can be omitted when the
signals to the peripheral circuit are in output status when seen from the target CPU. When pulling-up these
signals, the resistance should be more than 4.7kΩ.
Note 3. Execute the same procedure as “Note 2” for CE terminal. You may also choose to pull-up the terminal and
isolate without connecting to CE terminal on S550-SFWv3. When it is not used in the peripheral circuit,
you may fix it at H level on the board directly.
Note 4. Execute the same procedure as “Note 2” for EPM terminal. You may also choose to pull-down the
terminal and isolate without connecting to EPM on S550-SFWv3. When it is not used in the peripheral
circuit, you may fix it at L level on the board directly.
Note 5. Connect CNVss terminal to the CNVss on S550-SFWv3 by pulling-up or pulling-down with more than
4.7kΩ resistance.
Note 6. When the reset circuit on your target board is CR delay circuit or open collector output, or it is a circuit
with constant current load of less than tens of micron amperes, connect to the RESET terminal on
S550-SFWv3 directly. Execute the same procedure as “Note 2” for CMOS output.
Note 7. Vss terminal is signal ground. Be sure to connect it.
* Please check the hardware manual or the Data sheet of each microcomputer along with this connection
circuitry example.

[Circuitry Examples]
Note 1. When stand-alone programming, the power supply of S550-SFWv3 is provided by the user target board
via Vcc pins. Connect the power source of the board to the Vcc terminal directly.
Note 2. Isolate TXD, RXD, SCLK and BUSY terminals from the MCU peripheral circuit, in case the jumper,
analog switching, three-state, etc. are built in when serial programming. Isolation can be omitted when the
signals to the peripheral circuit are in output status when seen from the target CPU. When pulling-up these
signals, the resistance should be more than 4.7kΩ.
Note 3. Execute the same procedure as “Note 2” for CE, P16 and RP terminals. Connect the CE terminal to CE
terminal on S550-SFWv3, or connect either P16 or RP terminal to CE or EPM on S550-SFWv3. You may
also choose to pull-up the CE terminal, or pull-up the P16 terminal and pull-down the RP terminal, then
isolate from MCU peripheral circuit without connecting to CE or EPM terminal on S550-SFWv3. When it
is not used in the peripheral circuit, you may fix the CE terminal at H level, or the P16 terminal at H level
and EPM terminal at L level on the board directly.
Note 4. Connect CNVss terminal to the CNVss on S550-SFWv3 by pulling-down with more than 4.7kΩ or more
resistance. Do not connect a capacitor to this terminal. For other circuits, please consult with us.
Note 5. When the reset circuit on your target board is CR delay circuit or open collector output, or it is a circuit
with constant current load of less than tens of micron amperes, connect to the RESET terminal on
S550-SFWv3 directly. Execute the same procedure as “Note 2” for CMOS output.
Note 6. Vss terminal is signal ground. Be sure to connect it.
* Please check the hardware manual or the Data sheet of each microcomputer along with this connection
circuitry example.
