PRODUCTION DATA
All unused pins must be left as no connect (NC) pins. Table 7-3 provides a list of NC pins.
FUNCTION | SIGNAL DESCRIPTION | PIN NUMBER | ACCEPTABLE PRACTICE |
---|---|---|---|
DIO | Digital input or output | 3, 9, 10, 12, 18, 19, 22, 42, 53, 54 | Wake up I/O source should not be floating during hibernate. All the I/O pins will float while in Hibernate and Reset states. Ensure pullup and pulldown resistors are available on board to maintain the state of the I/O. Leave unused GPIOs as NC |
No Connect | NC | 20, 21, 33, 39, 41, 45 | Unused pin, leave as NC. |
SOP | Configuration sense-on-power | 23, 24, 34 | Leave as NC (Modules contain internal 100 kΩ pull down resistors on the SOP lines). An external 10 kΩ pull up resistor is required for factory restore. See Section 9.5. |
Reset | RESET input for the device | 35, 36 | There is an internal 100 kΩ pull-up resistor option from the nRESET pin to VBAT_RESET. Note: VBAT_RESET is not connected to VBAT1 or VBAT2 within the module. The following connection schemes are recommended:
