Real-time clocks (RTCs) and timers are essential components in industrial automation, consumer electronics, and embedded systems, rather than a specific brand. Leading manufacturers include Microchip Technology (USA), Texas Instruments (USA), Maxim Integrated (USA), NXP Semiconductors (Netherlands), and STMicroelectronics (Switzerland). These companies produce RTCs and timers that provide accurate timekeeping, event scheduling, and system synchronization for applications like smart meters, medical devices, and IoT systems. Products range from standalone RTC ICs to integrated timer modules with features like battery backup and temperature compensation. Industrial suppliers like Radwell and Grainger distribute these components alongside other automation and control equipment.
