LC89058W-E
7.5 Points to Notice about Replacing
• When replacing the LC89057W-VF4A-E with the LC89058W-E, it may be necessary to review the circuit pattern
design of the printed circuit board in advance depending how the device is used. Particular attention should be
directed to pins 44 to 48 whose I/O functionality can be set according to the INT pin setting. This section contains
the notes and cautions to be observed when replacing the LC89057W-VF4A-E with the LC89058W-E. For details of
the INT pin, see Chapter 9, Initial System Settings and Chapter 10, Description of Demodulation Function.
• Refer to the specifications of LC89057W-VF4A-E when replacing LC89058W-E with LC89057W-VF4A-E.

Figure 7.1 Change from LC89057W-VF4A-E to LC89058W-E (when the INT pin is set to pull-down)
• In this case, the system that doesn't use a modulation function or a general-purpose I/O function can be replaced with
LC89058W-E.
• After the replacement, LC89058W-E is used on condition that it pins 44 to 47 connect with GND and pin 48 open.
