Figure 7.4 Change from LC89058W-E to LC89057W-VF4A-E (when the INT pin is set to pull-down)
• It is necessary to review the circuit pattern of the printed circuit board to change the pull-up resistor of pin 35 to the
pull-down resistor because pins 44 to 47 is used as general purpose I/O input function.
• It is necessary to review the circuit pattern of the printed circuit board because the I/O setting of pin 48 differs from
each other.
• After the replacement, the RXOUT2 output of LC89057W-VF4A-E cannot be used.

• After the replacement, pins 44 to 47 can be used as general purpose I/O output function. However, it is necessary to
review the circuit pattern of printed circuit board because pin 48 has to GND.
• After the replacement, the RXOUT2 output of LC89057W-VF4A-E cannot be used.
