SPI general purpose I/O expanders
General purpose I/O expanders provide GPIO expansion for most microprocessor families allowing designers to save the GPIOs on microprocessors for other important functions.
As more features and processing requirements, such as LED control, hardware control monitors, and humidity sensors in the computing space are added to applications, the limited numbers of GPIOs on microprocessors are becoming more valuable. By implementing our I/O expanders, designers can utilize the microprocessor GPIOs for important functions and use the I/O expander for other duties including system monitoring, ACPI power switches, sensors, push buttons, LEDs, fans, etc.
GPIO are ideal for adding fan and LED control to systems. They are also ideal for monitoring system functions and accepting push-button inputs.
Our new products provide General Purpose Input (GPI) expansion capabilities for SPI-bus systems.
