XRA1202IG16-F is an integrated interface-I/O (Input / Output) expander chip from TI (Texas Instruments). It is a highly configurable device that expands the capabilities of controllers and processors to control a range of peripheral devices, by providing additional I/O port functionality. It is available in a 32-pin variant, operating at a voltage range of 1.8V to 5.5V.

The XRA1202IG16-F is ideally suited to industrial and process control applications, with its ability to communicate point-to-point with a range of peripheral devices including meters, sensors, and digital-analog devices. It also has the power to process digital signals from very low level current signals or from 5V logic devices. The IC is kept small and compact, making it ideal for a range of physical locations, from harsh temperature zones to confined or restricted areas.

The XRA1202IG16-F chip comes with programmed Input and Output connections on each of its 32-pins, allowing for diverse interfacing possibilities. It enables the user to control multiple devices from a single source, by connecting multiple I/O pins to a single bus. To make it easier to set up, a range of selectable parameters are available, to set the pin’s voltage-level, polarity and output-path configuration.

The chip provides 8 bidirectional I/O channels, 4 general purpose I/O pins, 2 interrupts, and a low-power shutdown mode. A specially designed low-voltage-detector ensures that the chips starts in a known configuration when the power supply is lower than 1.75 volts. Additionally, safety features such as open-drain protection, stop-on-disable input, and inputs-at-power-up bolster its capabilities.

The XRA1202IG16-F chip is available in both affixed-mount and pin-mount packages, for ease of installation and use. Each of these packages also comes with a range of configurable GPIO (General-Purpose Input/Output) ports and a DMA (Direct Memory Access) bus for simplified control.

In general, the XRA1202IG16-F is an ideal chip for interface-I/O (Input/Output) expander applications. It provides a high degree of flexibility, allowing users to tailor the components and pins to different applications. With its array of features, the chip is ideal for a broad range of industrial applications, from process control to web server management. The chip is available in a wide range of variants, giving users the ultimate choice of control boards and chips.
