- The TCA9548A I2C Multiplexer Adapter enables seamless communication with multiple I2C devices that share identical addresses on a single I2C port. With 8 I2C interfaces, it allows for efficient management of bi-directional data transfer across the I2C bus. - Key Features: - Compatibility: Works with IIC Bus and System Management Bus (SMBus). - Flexible Voltage Support: Operates at voltage levels of 1.8V, 2.5V, 3.3V, and 5V, accommodating various devices. - Active Low Reset Input: Provides reliable reset functionality without needing to power off the device. - Hot Insertion Support: Allows for the addition or removal of devices without disrupting the system. - Low Standby Current: Ensures energy efficiency during operation. - Control and Configuration: - The programmable control register lets users select individual SCn/SDn channels or combinations of channels, providing customized control over device connections. - The default address is set to 0x70, with the option to change it between 0x70 and 0x77, enabling up to 8 expanders to be cascaded. This means you can connect up to 64 devices with identical addresses on a single I2C port. - Practical Applications: - Sensor Networks: Ideal for projects requiring multiple identical sensors, such as temperature or humidity sensors, connecting seamlessly to a single microcontroller. - IoT Devices: Perfect for Internet of Things applications where numerous devices need to communicate over a single bus without address conflicts. - Embedded Systems: Useful in complex embedded systems where various modules need to share the same communication lines without interference. - In case of a timeout or malfunction, the TCA9548A can be reset by setting the /RESET input to Low. A power-on reset automatically selects all channels, initializing the I2C/SMBus state machine for reliable operation.
