Cautions for mounting of IC
Note1 : For external part constant, the recommended value is described. Since the constant may differ during actual use
with the set mounted, be sure to consider optimization.
Note2 : The differential input antenna application is described. Single input with pin 1 only is also possible.
Note3 : If the spike noise between MPU and IC is large during communication, it is recommended to add limiting
resistors R1, R2, and R3 between MPU and IC. 0
at 1.8V.
Note4 : To reduce noise from power supply, add a capacitor between VCC - GND and between VDD - GND.
Note5 : The I2C bus communication line requires pull-up resistors R5 and R6. The commonly-employed resistance value
is 2.2k. Set the pull-up voltage to the same one of VIO of LV24230LP-A. (Supply from the same source as VIO
and VDD is recommended.
Note6 : Please use the INT pin arbitrarily. Recommended to open when unused.
The INT pin becomes unstable at IC startup. To protect MPU from any effects during startup, it is recommended
to add either the pull-up or pull-down resistor to set the non-active mode. (This is not necessary when the MPU
can be set to non-active by a software during initialization.
