Microcontrollers
Microcontrollers are integrated circuits that combine a processor core, memory and peripheral functions to control electronic systems. They are widely used in industrial control, automotive electronics, consumer devices, communication equipment, medical electronics, IoT products, smart home devices, automation systems and embedded applications.
This category includes 8-bit microcontrollers, 16-bit microcontrollers, 32-bit microcontrollers, low-power MCUs, automotive MCUs, wireless MCUs, general-purpose MCUs and application-specific embedded controllers. These components are commonly selected based on core architecture, clock speed, memory size, interface support, operating voltage, package type, temperature range and application requirements.
TomatoElec supplies original Microcontrollers from recognized semiconductor manufacturers such as STMicroelectronics, Microchip, NXP, Texas Instruments, Renesas, Infineon, onsemi, Analog Devices 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.
