The Cypress CY14B512P combines a 512-Kbit nvSRAM with a full-featured real time clock in a monolithic integrated circuit 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。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). The STORE and RECALL operations can also be initiated by the user through SPI instruction.

Dear valued customer,

Thank you for choosing our products. They come with all the know-how and passion that our engineers have put into it. As you probably already know, Cypress is now Infineon. This is a major step for our company, but also for the good of you.
