Jeking Daily Post: RX-8025T

#High-Precision, #Low-Power, #I2C-Interface, #DTCXO, #Wide-Temperature **Introduction to the RX-8025T RTC Chip** The RX-8025T is a high-precision real-time clock (RTC) chip developed by Epson, designed for applications requiring accurate timekeeping and low power consumption. Featuring an integrated digital temperature-compensated crystal oscillator (DTCXO), this I²C-compatible device delivers exceptional timing accuracy across a wide temperature range. With its compact 10-pin SSOP package and built-in 32.768 kHz oscillator, the RX-8025T eliminates the need for external crystals, simplifying PCB design and improving system reliability. **Key Features and Performance** The RX-8025T stands out with ±3.8 ppm accuracy thanks to its internal DTCXO, ensuring minimal time drift even under fluctuating environmental conditions. It operates on a wide supply voltage from 1.6V to 5.5V, making it suitable for both battery-powered and industrial systems. The chip consumes only 0.8 μA at 3V typical, enabling long-term operation in backup power mode. Additional features include leap year correction (from 2000 to 2099), programmable alarm and periodic interrupt functions, and a 32.768 kHz frequency output with OE control. Its support for I²C bus high-speed mode (up to 400 kHz) ensures fast and reliable communication with microcontrollers. **Main Application Scenarios** This RTC chip is widely used in smart meters (electricity, water, and gas), industrial automation, security systems, medical devices, and embedded systems that require precise timestamping. Its high accuracy and ultra-low power make it ideal for FTU (Feeder Terminal Units) and other critical infrastructure where time integrity must be maintained during power outages. **Jeking Electronic Limited – Your Trusted Partner** Jeking Electronic Limited offers genuine RX-8025T chips with stable supply and technical support.
