概述

Description

The TCA9535RGER is a 16-bit I²C I/O port expander designed to increase the number of GPIO (General Purpose Input/Output) pins available to a microcontroller or microprocessor. It operates through an I²C interface, allowing for easy communication and control over multiple devices using only two wires (SDA and SCL).
With its 16 GPIO pins, the TCA9535 can be configured individually as inputs or outputs, making it suitable for applications requiring multiple digital signals. The device supports interrupt functionality, enabling it to notify the host controller of changes in input states, which is beneficial for efficient power management and responsiveness.
Operating with a supply voltage range of 1.65V to 5.5V, the TCA9535 is versatile for various systems, including low-power applications. Its compact package and ability to daisy-chain multiple devices make it an ideal choice for expanding pin functionality in embedded systems, robotics, and consumer electronics.
