Analysis of Non-Vibration of EP9302 RTC Oscillator
Zhaohui Jing · Journal of Physics Conference Series · 2019
The paper analyzes the problem of the non-vibration of the RTC oscillator of the ARM9 microprocessor EP9302. It points out the main causes of the problem and the matters that need attention in the circuit design. It also gives an example of a solution to solve such problems. The program has been tested in the environment with high temperature and low temperature. The results show that the ratio of the RTC circuit that does not vibrate at -10 degrees Celsius is reduced from greater than one percent to four out of ten thousand, which can be used by the relevant design and application personnel of EP9302.
