I am unable to use the RTC PFC8523. i am getting the following in the dmesg:
pi@raspberrypi:~ $ dmesg | grep rtc
[ 5.725960] rtc-pcf8523 1-0068: failed to set xtal load capacitance: -121
[ 5.726604] rtc-pcf8523: probe of 1-0068 failed with error -121
PCF8523 Error in dmesg

Using 5 volt for VCC.

Re: PCF8523 Error in dmesg
Try switching to 3V for VCC. The Pi is a 3V board.

Re: PCF8523 Error in dmesg
I get the same thing on 3 volt, but i will try again and see. Also, if this is only a 3 volt item then you need to change the description.
"Equipped with PCF8523 RTC - it can run from 3.3V or 5V power & logic!"

Re: PCF8523 Error in dmesg
It's not 3V only. But you need to match power to your board's logic level. From link above.
In your case, it's 3.3V.This chip can be powered by 3-5VDC so there is now on-board regulator. To power the board, give it the same power as the logic level of your microcontroller - e.g. for a 5V micro like Arduino, use 5V

Ahh gotcha. I have it on 3.3v pin and i am not showing ID #68 in my i2cdetect output:
pi@raspberrypi:~ $ sudo i2cdetect -y 1

60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --
I have confirmed the voltage on the rtc and it matches whats coming out of the pi. Could i have hosed it when connecting to 5v??

Re: PCF8523 Error in dmesg
This is what i get when i did a full restore, before and after adding the dtoverlay=i2c-rtc,pcf8523 to the config.txt. This is on both a rpi 3b+ and a 4 4gb:

Re: PCF8523 Error in dmesg
Attaching to 5V would not have damaged the PCF. You risk damaging the Pi's pin though, since VCC sets the voltage level.
Do you have another I2C device and/or another Pi? (or even something like an Arduino board)

Re: PCF8523 Error in dmesg
Ah, I think I missed this. Doing the same on both. Hmmm. Not sure. It should show up with the I2C scan. Even without a battery installed.This is on both a rpi 3b+ and a 4 4gb:
Let's replace it and see what happens. Send an email to [email protected] with a link to this thread and your order number and they can send you a replacement PCF8523 RTC.
