Epson announced two new Real Time Clock (RTC) module families – the Epson RX4901CE and RX8901CE family for industrial and commercial markets and the Epson RA4000CE and RA8000CE family for the automotive market. These new solutions expand Epson’s current line of RTC modules, integrating the crystal unit and IC into a single package for ease of implementation in a range of commercial and automotive applications. They move toward higher efficiency, lower power, higher accuracy over extended temperatures, and higher integration of functionality, Epson continues to invest in its RTC portfolio to address the most demanding market needs. The new RTC modules offer system builders a variety of options that deliver the best combination of features and price points with trusted industry-leading technology.
The Epson RX4901CE and RX8901CE Family
The RX4901CE and RX8901CE are ideal for a variety of applications, including utility smart meters, surveillance security systems, industrial factory automation equipment, commercial smart lighting systems, and other small electronic products. The RX4901CE and RX8901CE RTC modules have an integrated 32.768 kHz digital temperature compensated crystal oscillator (DTCXO). The modules include a rich feature set with up to three event detection pins, and functions such as a time stamp function that can record up to 32 dates and times when an external or internal event occurs, as well as the basic RTC functions such as time and calendar, time alarm, wakeup timer, and time update interrupts. With the combination of an auto power switching function, which includes a control circuit to prevent reverse current to the main power supply, a continuous temperature-corrected 32.768 kHz clock generation, and Seiko Epson’s original low current consumption technology, the RX4901CE and RX8901CE realize long battery life on various systems.
The Epson RA4000CE and RA8000CE Family
They Ideal for battery management systems, in-vehicle networking and infotainment systems, the RA4000CE and RA8000CE are automotive RTC modules with integrated 32.768 kHz digital temperature compensated crystal oscillator (DTCXO). This module includes various functions such as a second-to-year clock/calendar with a leap-year correction, time alarm, wakeup timer, time update interrupts, clock output, a time stamp function that can record two times and dates when an external or internal event occurs and reset self-monitoring functions. These products are compliant with AEC-Q100 and low-power operation, making them suitable for automotive applications.
