RA-8565SA (for Automotive I2C-Bus Interface Real Time Clock Module)

Epson has launched a real-time clock module (RTC) RA-8565SA specifically designed for the automotive industry, which complies with the AEC-Q200 automotive standard and has the advantages of low power consumption, high precision, high stability, and wide temperature applicability. Built in 32.768kHz crystal oscillator with a frequency tolerance of only 5 ± 23ppm (TA=25 ℃), CLKOUT as the output pin (N-channel open drain output). The working temperature can reach up to 125 ℃, meeting the requirements of the automotive industry, greatly improving the efficiency and applicability of the system. The characteristics of miniaturization and low loss make the RA-8565SA series in car clock chip an ideal choice for in car RTC modules due to its advantages of high operating temperature, low power consumption, and high precision. It can be widely used in car audio equipment, instrument panel car navigation systems, ECU, etc., and can provide more accurate clock signal output in car environments with drastic temperature changes.
