Details
The PCA9555DWR stands out as a comprehensive 16-bit I/O expander designed for operation within a voltage range of 2.3-V to 5.5-V VCC. It offers versatile remote I/O expansion for various microcontroller families via the I2C interface, making it a valuable component for different applications. The device includes two 8-bit Configuration, Input Port, Output Port, and Polarity Inversion registers, allowing for convenient input or output selection and polarity inversion. Upon power up, the I/Os default to inputs, but the system master can easily configure them as outputs by modifying the I/O configuration bits. The corresponding Input or Output register efficiently stores data for each input or output, ensuring seamless data management. Moreover, the Polarity Inversion register allows for the inversion of the Input Port register to cater to diverse system requirements. The accessibility of all registers by the system master further enhances the PCA9555DWR's usability in various applications, providing a comprehensive solution for I/O expansion and integration
