Real Time Clock (RTC)
Let me start by giving you some background on my device, my device is battery operated, when the battery is in its turned on when its not its off, I use a RTC to keep track of the amount of time that passes between uses of my device, it has an independent battery to keep the RTC powered. I'm currently using a M41T94MQ6E (RTC with 44B of Ram that communicates through SPI) and a 25AA320A (32K memory storage) for my RTC information storage.
Is it possible to replace all that functionality on the CY8C5568AXI-060? I basically need to know when my device is turned on and how much time passes between the periods where its turned off. I have a small coil cell battery on my board that powers the RTC when the primary battery is not in the device.
