功能概述
The Cypress CY14B512Q1/CY14B512Q2/CY14B512Q3 combines a 512-Kbit nvSRAM with a nonvolatile element in each memory cell with serial SPI interface. 该存储器采用“64 K 字,每字 64 位”的组织方式。嵌入式非易失性组件通过采用量子井技术,打造出世界上最可靠的非易失性存储器。SRAM 能够实现无限次读写循环,而量子井单元则能够提供高度可靠的非易失性数据存储空间。Data transfers from SRAM to the nonvolatile elements (STORE operation) takes place automatically at power-down (except for CY14B512Q1). On power-up, data is restored to the SRAM from the nonvolatile memory (RECALL operation). The STORE and RECALL operations can also be initiated by the user through SPI instruction.
