Section 4 User System Interface Circuits
4.1 User System Interface Circuits
Some signals from the optional EV-chip unit are connected to ICs and pull-up resistors.
Figures 4.1 through 4.12 show user system interface circuits. Use the figures as a reference in
determining the values of the pull-up resistors.

Notes: 1. If the product revision of the R0E570800VKK00 EV-chip unit is a letter from A to H
at shipment from the factory, the value of the pull-up resistor will be 47 kΩ.
2. If the product revision of the R0E570800VKK00 EV-chip unit is a letter from A to H
at shipment from the factory, neither the LVTH16244 nor CB3T16211 will be
mounted. Signals from the user system are connected to EP1K100FC.
3. The product revision at the time of shipment from the factory is printed on the edge of
the R0E570800VKK00 board. Check the alphabetic character following the six-digit
number.
