Hi everybody!
I have got a question concerning the Real Time Clock of the LPC2119 processor: Is it possible to save the values of the RTC (i.e. the time and date) with a battery as the only power source (i.e. without external 1.8V / 3.3V supply) ? If so, how does this work in detail? Thanks in advance.
No, I didn't. But I did set up an experiment, and it worked. I connected a gold-cap via some components to the 1.8V pin and switched the processor in power-down mode. Now, I only have to check how long time and date are preserved. Thanks for your reply.
