6. ESD Protections
External ESD protections are available on the WISMO Series Development Kit for the following
signals:
•
SIM interface signals: SIM-VCC, SIM-IO, SIM-CLK, and SIM-RST
Other interface signals protected on the WISMO218 are as follows:
• UART1 signals with the ADM3307 transceiver
•
UART2 signals with the LTC2804 transceiver
Caution:
As the test points at the center of the WISMO Series Development Kit are not protected against ESD
discharge and they are directly connected to the signal pins of the WISMO218 or the WISMO228,
users must be careful when using these TP signals.
