CYONS2001
DC General Purpose I/O Specifications
GPIOs are arranged into four ports. Ports 0, 1, and 2 have eight GPIO pins and Port 3 has four GPIO pins. Port 1 has an optional low
drop out (LDO) regulator that adjusts the port’s output voltage to 1.8, 2.5, or 3.0 V. Additionally, each GPIO pin can be independently
set to one of four drive modes: strong drive, open drain, pullup, or high-Z analog.
Rise and fall times are specified for 10% and 90% voltage values.
The following tables list guaranteed maximum and minimum specifications for the voltage range of 2.7 V to 3.6 V at the DVDD pin,
and over the temperature range 5 °C ≤ T_A ≤ 45 °C. Typical parameters apply to 3.3 V at 25 °C and are for design guidance only.
