TKD's Real-Time Clock (RTC) modules integrate a high-precision 32.768kHz crystal unit with ultra-low power consumption (2.2μA typ. @3V) and high-accuracy timekeeping. The modules feature a built-in Digital Temperature-Compensated Crystal Oscillator (DTCXO), achieving ±5ppm frequency stability over the full temperature range. The automotive-grade RTC (TR8804), built with a MEMS tuning-fork crystal resonator and qualified to AEC-Q100/Q200, delivers stable high-precision second-pulse signals across -40~105℃. Widely deployed in smart meters, industrial control, IoT, and automotive electronics including BMS, T-BOX, and ADAS.
TKD RTC modules integrate a high-precision 32.768kHz crystal unit, with typical current consumption as low as 2.2μA@3V, delivering ultra-low power consumption. The modules support a wide operating voltage range of 1.8~5.5V and feature integrated battery backup switching functionality, making them ideal for long-term precision timekeeping in battery-powered applications such as smart wearables, IoT terminals, and smart meters.
TKD RTC modules feature a built-in Digital Temperature-Compensated Crystal Oscillator (DTCXO), achieving ±5ppm frequency stability over the full temperature range (equivalent to approximately 0.2 minutes of monthly time deviation). The automotive-grade TR8804 employs a MEMS tuning-fork crystal resonator with an integrated high-precision temperature compensation IC, delivering high-accuracy time base output across a wide temperature range of -40~125℃, with support for 32.768kHz temperature-compensated signal output and high-precision second-pulse signal output.
TKD automotive-grade RTC modules (TR8804/TR8804C) are AEC-Q100 qualified, complying with international automotive-grade standards. The products employ a MEMS tuning-fork crystal resonator with an integrated high-precision temperature compensation IC, hermetically sealed in a high-strength ceramic package. They are widely deployed in BMS (Battery Management System), T-BOX (Telematics BOX), ADAS (Advanced Driver Assistance System), smart cockpits, infotainment systems, and other core automotive electronic applications.
TKD's automotive-grade crystal resonators have passed our stringent qualification audits, demonstrating exceptional supply capability and quality management system recognition. With full-scenario coverage across body, ADAS, and cockpit domains, TKD is a trusted domestic supply chain partner.
TKD products deliver stable performance and high reliability, with 17 models certified on our HiSilicon platforms. As a leading domestic crystal oscillator R&D manufacturer, TKD is a key partner in our frequency control device supply chain.
TKD's 1612-size 19.2MHz crystal resonator was the first to pass Qualcomm Snapdragon AR1+ Gen1 platform certification and achieve mass production. Its ultra-low ESR and miniaturized package perfectly fit our AI glasses, enabling extreme thinness and extended battery life.
