CHAPTER 5 CONTROL CIRCUITY

5. Introduction to the chapter

Here you can find information about reset circuit and quartz crystal locations.

5.1 Reset

STM32-P407 reset circuit includes R65 (10 KΩ), R66(560 Ω), C45(100 nF), STM32F407ZGT6 pin
25 (NRST) and a RESET button. The RESET is also connected to the proto area.

5.2 Clock

25 MHz quartz crystal Q1 is connected to pins 23 and 24 of the processor.

Real time clock (RTC) Q2 is found at pins 8 and 9 of the processor.
