- The TCA9548A adapter allows seamless communication with multiple I2C devices that share identical addresses on the same I2C port of the main control board. This capability enables you to connect up to 8 identical addresses after integrating just one expander. - Each expander comes with a default address of 0x70, which can be modified to any address between 0x70 and 0x77 as required. This flexibility means you can theoretically cascade up to 8 expanders, allowing for a total of 64 devices with the same address to be connected and operated efficiently via the same I2C port. - The TCA9548A expansion board is fully compatible with IIC Bus and System Management Bus (SMBus). It features: - Active Low Reset Input for hot insertion - Low standby current to minimize power consumption - No interference during power-up - Support for voltage levels of 1.8V, 2.5V, 3.3V, and 5V - Level shifting capabilities for enhanced functionality - Programmable control registers allow precise selection of individual SCn/SDn channels or combinations of channels for tailored communication. - In the event of a timeout or malfunction, the system master can reset the TCA9548A by setting the /RESET input to low. A power-on reset will disable all channels and initialize the I2C/SMBus state machine, ensuring reliable operation without the need to power down the device. Use Scenarios: 1. Connect multiple temperature sensors with identical I2C addresses in a smart home system to monitor various rooms simultaneously. 2. Integrate several identical displays in an automated data visualization setup, managing them efficiently through a single I2C port. 3. Use in robotic applications where multiple identical sensors need to relay information back to a central controller without address conflicts.
