This is an Obsolete Application Note
The document AN2300 - User Interface - Non-Volatile Memory Controller with Realtime Clock has been marked as obsolete. The obsolete version of this application note is still available with the below description but may not be complete or valid any longer. If you have any questions or require support in regards to the below application note content, please click here and create a technical support case.

This Application Note describes a PSoC® non-volatile memory controller. It is used to retain the values in the CMOS SRAM for long periods of time when the primary power supply is disconnected or falls below the minimum specified voltage. This design uses a battery as the secondary power supply. Also, a realtime clock is included for a very robust solution.
