RTC chips can provide precise time information for systems, helping to achieve functions such as timing control, event recording, and timestamp generation. In various fields such as communications, power, industrial control, automotive electronics, security monitoring, instrumentation, smart healthcare, smart cities, smart homes, smart appliances, and consumer electronics, the application of RTC chips is becoming more and more popular.
Facing intense market competition and more application scenarios, Dapu has launched a new upgraded separate RTC - INS5T8563. This chip is designed to fully consider the requirements of modern electronic devices for high precision, low power consumption, low cost, high stability, and environmental adaptability.
INS5T8563 is an industrial-grade and low-power RTC chip with I²C interface and versatile functions. It not only provides accurate year, month, week, day, hour, minute, and second timing, but also supports programmable clock output, interrupt output, low voltage detection, timers and alarms. With outstanding performance, it can be widely used in various electronic products and devices such as industrial control, security monitoring, automotive electronics, smart homes, smart appliances, consumer electronics and AIoT fields.
Functional Structure:
INS5T8563 consists of an Oscillator, RTC core, Power Management, I²C Interface, Interrupt/Fout circuit and Registers.

Among them, the oscillator is mainly used to activate the external crystal oscillator, and the RTC core is responsible for generating standard time signals. The chip also configures with 17 addressable 8-bit parallel registers, controlling register status, year, month, week, day, hour, minute, second, alarm, and timer. In terms of power management, the chip can provide current for digital circuits, oscillation circuits, reference circuits, and startup circuits. At the same time, I²C provides users with a human-machine read/write interface, allowing users to freely program various functional outputs for easy and convenient use to meet diverse needs. In addition, the chip’s interrupt output circuit can also output different frequencies (32K/1024/32/1Hz), timing interrupts and alarm interrupts.
