CY14B256K Description
The Cypress CY14B256K bines a 256 Kbit nonvolatile static RAM with a full featured real-time-clock in a monolithic integrated circuit. The embedded nonvolatile elements incorporate QuantumTrap technology producing the world’s most reliable nonvolatile memory. The SRAM can be read and written an infinite number of times, while independent, nonvolatile data resides in the nonvolatile elements.
