Epson is a company that independently develops IC and crystal technology, with its own IC and crystal oscillator production lines. So we can package the RTC IC+crystal unit+external junction capacitor together to form an independent RTC module. There is no need to connect crystals and matching capacitors on the periphery. Epson RTC can simplify customer design and production.

Clock accuracy: calibration of clock accuracy, crystal screening, and extra detection

Stability of oscillators: matching testing, saving profits from crystal units, and designing oscillation circuits

The above TRC products are mainly divided into four categories based on the application environment:

1. A high-precision RTC (High Stability) with temperature compensation function, applied in application environments with high precision requirements for the entire temperature range, such as gas meters, electricity meters, and other instruments. The highest accuracy at full temperature can be achieved+ -3.4ppm@-40 ~85 degrees.

2. Low power RTC, this type of RTC has ultra-low power consumption characteristics, only 0.13uA. When using a backup battery EDLC, it can be used for up to 13 weeks. The ordinary MCU's built-in clock can stand by for less than 2 weeks. Mainly used in equipment with ultra long standby function requirements, such as gas detection, alarm detection, etc.

3. The third type is RTC compatible with the SOP-8 series, and Epson's real-time clock modules are an excellent supplier in terms of global supply. The most commonly used product in the market is the SOP-8 packaged RTC. Epson's RX8010 series is compatible with this type of RTC. And there is no need for an external crystal circuit. It can be directly replaced and used. Economical and fast replacement. For example, applications with low requirements such as industrial control, equipment counting and timing, etc

4. The last category is the ultra small packaging RTC, which is only the size of a regular 3225 crystal and has a power consumption of only 0.3uA. And there is no need for an external crystal circuit. Low price and excellent performance. Mainly used in small package design, such as smartwatches, IoT communication modules, and small modules.
