Mobile I/O Expander & Keypad Controller
Analog Devices' family of mobile I/O expanders are ideal for smartphone designs and portable devices that require a large extended keypad and/or expanded I/Os such as inventory scanners, medical equipment, and meter readers. Microprocessors in portable systems are GPIO constrained due to the number of functions they must interface with and control. They are also power hungry, making them inefficient for debouncing, polling, and key press scanning algorithms. ADI’s family of mobile I/O expanders offloads key scan and GPIO functions from the CPU, freeing up the processor for higher priority functions while saving energy.
