Infineon 1Mbit 25ns NVRAM, 16-Pin SOIC, CY14V101Q3-SFXI

The Cypress CY14V101Q3 combines a 1 Mbit nvSRAM with a nonvolatile element in each memory cell with serial SPI interface. The memory is organized as 128 K words of 8 bits each. The embedded nonvolatile elements incorporate the QuantumTrap technology, creating reliable nonvolatile memory. The SRAM provides infinite read and write cycles, while the QuantumTrap cell provides highly reliable nonvolatile storage of data. Data transfers from SRAM to the nonvolatile elements (STORE operation) takes place automatically at power-down. On power-up, data is restored to the SRAM from the nonvolatile memory (RECALL operation). Both STORE and RECALL operations can also be initiated by the user through SPI Instruction.
