The SLG7IO is a portfolio of pre-configured GreenPAK™ I/O expander standard designs that extend GPIO capability and consolidate digital control functions. The collection includes GPIO and I²C- or SPI-controlled expansion options, from compact 6-GPIO implementations to designs supporting larger input and output counts. Each standard design is ready for evaluation and can be customized for specific I/O counts, control logic, interface behavior, and package requirements. These designs were configured using the Go Configure™ Software Hub and can be further modified to meet custom requirements upon request.
