Interface - I/O Expanders, PCF8575TS/118 is a single chip device that extends the number of available digital input/output (I/O) lines to a binary system, typically a microprocessor. The device is designed to extend the number of I/O pins beyond what is physically available on the microprocessor by using a serial data line. The PCF8575TS/118 increases the number of I/O lines available from a microprocessor by up to 16 I/O pins. It supports both Totem-Pole and Open-Drain Input/Outputs. The device has sixteen ports, each one of which is individually programmable as an input or output line. There are two input/outputs (DIPs), 8-bit Bidirectional data bus lines, and a Serial Input/Output Line. The device also features a Serial Input pin, PWRDWN pin, OE pin, and an interrupt output pin.

The PCF8575TS/118 includes a 16-bit Non-Volatile Static Random Access Memory (SRAM), which can be used to save the data when the device is powered down. The data can be re-populated when the device is power up again. The device also has a set of register latch inputs that are used to store the data in the registers during a power cycle. The data stored in the registers is stored in 8-bit banks, so the device can store up to sixteen bits of data. The device also includes an internal 5V regulator to ensure that the device is protected against surges and other adverse conditions.

The PCF8575TS/118 is mainly used in applications such as industrial automation and control, automotive, consumer electronics, medical devices, and smart home devices. In industrial applications, the device is typically used to provide additional I/O lines for communications, sensing, and control of industrial machinery. In automotive applications, the device is typically used to provide additional I/O lines for communications, sensing, and control of automotive systems. In consumer electronic applications, the device typically used for audio and video switching, controlling, and power management. In medical applications, the device can be used for sensing and monitoring systems.

The working principle of PCF8575TS/118 is simple. First, the data is written to the device’s RAM and then the appropriate control bits are set to enable the desired I/O lines. The data can then be read from the device by setting the appropriate control bits. The data can then be written back to the device by setting the appropriate control bits. The device also features an interrupt signal that can be used to invoke an interrupt handler in the system.

In conclusion, the PCF8575TS/118 is a single chip device that extends the number of available digital input/output (I/O) lines to a binary system. It is mainly used in industrial applications. The device features a 16-bit non-volatile static random access memory (SRAM), 8-bit bidirectional data bus lines, and a serial input/output line. The working principle of the device is simple, data is written and read to and from the device by setting the appropriate control bits. The interrupt signal available on the device can be used to invoke an interrupt handler in the system.
