0755-82798135UARTs (Universal Asynchronous Receiver Transmitter)
UARTs (Universal Asynchronous Receiver Transmitters) are interface ICs used for asynchronous serial communication between microcontrollers, processors, sensors, modules and external devices. They are widely used in industrial control, communication equipment, embedded systems, consumer electronics, automotive electronics, medical devices, IoT products and test instruments.
This category includes UART interface ICs, serial communication controllers, multi-channel UARTs, bridge ICs, transceiver-related UART devices and related data communication components. These devices are commonly selected based on channel count, baud rate, interface type, FIFO depth, supply voltage, package type and system compatibility.
TomatoElec supplies original UART Interface ICs from recognized semiconductor manufacturers such as Texas Instruments, NXP, Microchip, STMicroelectronics, Analog Devices, onsemi, Diodes Incorporated, Renesas and other major brands. As an in-stock electronic components supplier and independent distributor, TomatoElec provides inventory support, original component sourcing and BOM sourcing services for global customers.
