The XRA1403IL24-F is a 16-bit GPIO expander featuring an SPI interface, designed to operate within a voltage range of 1.65V to 3.6V. It includes 16 general-purpose I/Os (GPIOs) that can be individually configured as inputs or outputs, with options for high, low, or three-state output modes. The device supports 5V tolerant inputs and has internal 100K ohm pull-up resistors that can be enabled or disabled for each GPIO. The XRA1403IL24-F allows for programmable interrupt configurations, including rising edge, falling edge, or both, and features a maximum standby current of 1µA at +1.8V. It operates with an SPI clock frequency of up to 26MHz and provides 3kV HBM ESD protection. The device is available in both 24-pin QFN and TSSOP packages, making it suitable for various applications, including personal digital assistants, cellular phones, and battery-operated devices.
