3.3 Electrical Information for Digital I/O
The three types of digital I/O on the Q2686 Wireless CPU
1.8Volt CMOS and Open drain.
The three types are described below:
*Absolute maximum ratings
All 2.8V I/O pins do not accept input signal voltage above the maximum
voltage specified above, except for the UART1 interface, which is 3.3V tolerant.
Internal 1V8 power supply
*Absolute maximum ratings
