In the era of intelligent connectivity where time becomes critical data, the precision and reliability of system time are absolutely vital.

Whether it's precise billing from a smart meter, data recording from an industrial sensor, or every screen wake-up from a smartwatch, there must be a stable and reliable real-time clock (RTC) chip behind it as the time guardian.

Today, we proudly introduce the high-performance real-time clock module from EPSON – EPSON RX8900CE is not only a time recorder but also the cornerstone of system stability and low-power operation, built with EPSON's advanced quartz crystal technology.

Why Choose EPSON RX8900CE? Four Core Advantages

EPSON RX8900CE is not just an RTC chip; it represents EPSON's deep technical accumulation, designed specifically to meet the requirements of demanding application scenarios.

1. Ultimate Precision, Beyond Standards

Built-in high-precision compensated crystal oscillator (DTCXO): RX8900CE integrates a high-precision 32.768kHz crystal unit with an annual error controlled within ±5 minutes (at +25°C).

This far exceeds ordinary RTC chips, meaning your equipment won't need to worry about time 'drifting' throughout its long lifecycle.

2. Ultra-Low Power, Extended Battery Life

In timekeeping mode, its power consumption is as low as only 160nA (typical value).

This means longer standby time and more enduring battery life for battery-powered IoT terminals and smart wearable devices.

It's the ideal choice for creating 'maintenance-free' products.

3. Strong Anti-Interference and Stability

Built-in voltage detection and time stamp function: When the system encounters unexpected power loss or voltage fluctuations, the chip can automatically record the time of the event.

This provides critical basis for system diagnosis and data recovery.

Excellent shock and vibration resistance ensures stable operation in complex industrial and automotive environments.

4. Simplified Design, Fast Time-to-Market

Adopts miniaturized packaging to save valuable PCB space.

Compatible with I²C bus interface for easy connection with various host MCUs, greatly simplifying hardware design and software driver development processes.

This helps accelerate your product time-to-market.
