LE910Cx HW User Guide
Logic Level Specifications
Unless otherwise specified, all LE910Cx interface circuits are 1.8V CMOS logic. Only few
specific interfaces (such as MAC, USIM and SD Card) are capable of dual voltage I/O.
The following tables show the specifications of the logic level used in the LE910Cx
interface circuits.
Note: Do not connect LE910Cx digital logic signals directly to OEM
digital logic signals with a level higher than 2.7V for 1.8V CMOS
signals.
