功能概述

The Cypress CY14V101Q3 combines a 1 Mbit nvSRAM with a nonvolatile element in each memory cell with serial SPI interface. 该存储器采用“128 K 字,每字 128 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。断电时,数据会从 SRAM 自动转移到非易失性元件中(“存储”操作)。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.
