Functional Description
The Cypress CY14B116K/CY14B116M combines a 16-Mbit nvSRAM with a full-featured RTC in a monolithic integrated circuit. The nvSRAM is a fast SRAM with a nonvolatile element in each memory cell. The memory is organized as 2048 K bytes of 8 bits each or 1024 K words of 16 bits each. The embedded nonvolatile elements incorporate the QuantumTrap technology, producing the world’s most reliable nonvolatile memory. The SRAM can be re……
