The CY14B101KA-SP45XI is a 1-Mbit non-volatile SRAM with a full featured real time clock in a monolithic integrated circuit.

This SRAM is read and written an infinite number of times, while independent nonvolatile data resides in the nonvolatile elements. The real time clock function provides an accurate clock with leap year tracking and a programmable, high accuracy oscillator.
