Overview
NuMicro
™ NUC100/NUC120 Medium Density has up to 80 General Purpose I/O pins can be
shared with other function pins; it depends on the chip configuration. These 80 pins are arranged
in 5 ports named with GPIO
16 pins. Each one of the 80 pins is independent and has the corresponding register bits to control
the pin mode function and data.
NuMicro
™ NUC100/NUC120 Low Density has up to 65 General Purpose I/O pins can be shared
with other function pins; it depends on the chip configuration and package. These 65 pins are
arranged in 4 ports named with GPIOA, GPIOB, GPIOC and GPIOD with each port equips
maximum 16 pins and another port named
The I/O type of each of I/O pins can be configured by software individually as input, output, open-
drain or quasi-bidirectional mode. After reset, the I/O type of all pins stay in quasi-bidirectional
mode and port data register GPIOx_DOUT[15:0] resets to 0x0000_FFFF. Each I/O pin equips a
very weakly individual pull-up resistor which is about 110K
Ω~300KΩ for VDD is from 5.0 V to 2.5
V.
