Echtzeituhr-RTC-ICs sind Timing-Komponenten, die genaue Zeit- und Kalenderinformationen in elektronischen Systemen aufrechterhalten, auch wenn die Hauptstromversorgung ausgeschaltet ist. Sie werden häufig in Embedded-Systemen, Industrieelektronik, Unterhaltungselektronik, Kommunikationsgeräten, Medizintechnik, Automobilelektronik, IoT-Produkten, Messgeräten und Datenlogger-Anwendungen eingesetzt.

Diese Kategorie umfasst Real-Time-Clock-ICs, batteriegepufferte RTCs, Low-Power-RTCs, I2C-RTCs, SPI-RTCs, Kalenderuhr-ICs und verwandte Clock-/Timing-Komponenten. Die Auswahl erfolgt häufig nach Zeitgenauigkeit, Backup-Stromversorgung, Schnittstellentyp, Alarmfunktionen, Betriebsspannung, Stromaufnahme, Gehäusetyp und Anwendungsanforderungen.

TomatoElec liefert originale Echtzeituhr-RTC-ICs von anerkannten Halbleiterherstellern wie Microchip, NXP, STMicroelectronics, Renesas, Texas Instruments, Analog Devices, onsemi, Infineon und weiteren wichtigen Marken. Als lagerführender Lieferant und unabhängiger Distributor für elektronische Komponenten bietet TomatoElec Bestandsunterstützung, Originalbauteil-Beschaffung und BOM-Sourcing für internationale Kunden.
