1. FA Equipment
Power Switching for Low Current Consumption
Frequent battery replacement is required due to the high leakage current of the power switching circuit and rapid battery drainage.
Epson's RTC module, which has a built-in MOS switch for power switching, automatically switches the power. By reducing the leakage current, customers can reduce the frequency of battery replacement.
2. Smart Meters
Time Stamp for Tamper Detect Protection
- Need to monitor and record time when a malicious disassemble or destroy the smart meter is made
- Need to detect an unarthorized operation
The stand-alone RTC module with timestamp function receives input directly from external sensors and records it in internal memory. At the time of system setup, you can access the RTC module to check the presence or absence of a time stamp and time information to confirm the presence or absence of unauthorized operation and its time.
3. In-vehicle Cluster Meters
High Accurate Time Information under High Temperature Conditions
Customers have complained that the clocks are frequently out of alignment due to the high temperature fluctuations inside the car.
Epson's high-precision RTC modules conform to AEC-Q100/200 are deliver the equivalent of 9 seconds per month over a wide operating temperature range, potentially reducing end-user complaints.
4. Network Equipment
High Accurate Time Information Guarantees Characteristics when Trouble Occurs
It is connected to the network and synchronized with NTP (Network Time Protocol) under normal conditions, but it wants to guarantee holdover characteristics in case of failures.
RTC module with integrated DTCXO (Digital Temperature Compensated Xtal Oscillator) is the most accurate grade available up to +/- 3.4 ppm. Since it takes 0.9 seconds per day to convert to time, it can be used as reliable time information.
5. Security Equipment
High Accurate Time Information makes Encryption of security equipment
Security devices connected to the network are at risk of being cracked and having their data rewritten.
The standalone RTC module with high frequency accuracy (+/-3.4 ppm) and resolutions up to 1/1024th of a second provides network-independent timestamp data, including time information, for data encryption.
