I/O Expanders are devices that expand the current number of available input and output channels with respect to the systems controller. In practical terms, there is need for more input and output pins to control devices such as LCDs, segment LEDs, keypads or register additional buttons or switches, while at the same time reducing costs. I/O Expanders can provide these I/O pins at a low cost and, depending on the specific application, provide a simple solution for the overall design. One example of an I/O Expander is the Texas Instruments TCA9535DBR.
The TCA9535DBR I/O Expander provides 16 Expanders ports that can be used to access additional inputs or outputs. There are 4 input ports, 8 output ports, 2 input and output ports, and 1 port that can be configured as either an input or output. The TCA9535DBR also provides interrupt capability, which allows the user to simplify applications that require data to be processed in real time. In addition, the TCA9535DBR has programmable pull-up/pull-down resistors on each port for enhanced performance.
The main applications for the TCA9535DBR include systems that need access to multiple input and output connections, such as security control panels, embedded systems, monitoring systems, industrial systems and automotive systems. The device is also used in communications systems where multiple ports are needed to access different types of communication and data processing devices.
This I/O Expander works in the following way: first, the system controller communicates with the Expander via the two-wire bus interface using commands such as setting the ports direction, reading and writing data and configuring the interrupt system. The ports can be set as input or output and the port data states can be read or written. The device also supports interrupts, so if an input port state changes or a value is written to an output port, an interrupt can be generated.
The TCA9535DBR provides the user with a low cost and easy-to-use solution for the interface with multiple inputs and outputs. This provides an easy way to control additional LCDs, segment LEDs, keypads or register additional buttons or switches. In addition, the device offers advantages such as programmable pull-up/pull-down resistors and interrupt capability. All these features make this I/O Expander a great solution for various applications.
