CY8C5888. How to connect to the battery only RTC (real-time clock)?. What pin supply this device?
What is the device complete name. Also are you using a 5lp kit or some other one or is this your design? Also are you using the RTC component or are you using a clock device that is external to the board?
Welcome in the forum.
The RTC is a pure software solution and not designed for battery backup. To maintain this you will need an additional RTC chip or a means to receive a clock radio.
Thanks for the reply
