機能概要

The Cypress CY14MX064Q combines a 64 Kbit nvSRAM with a nonvolatile element in each memory cell with serial SPI interface. メモリは各 8 ビットの単語 8K として構成されています。組み込み不揮発性エレメントには、QuantumTrap テクノロジが組み込まれており、世界でも最高レベルの信頼性を誇る不揮発性メモリを作り上げます。回数に制限のない読み取りと書き込みをSRAMで可能にする一方、高い信頼性を提供する不揮発性データ記憶域をQuantumTrapセルで実現しています。Data transfers from SRAM to the nonvolatile elements (STORE operation) takes place automatically at power-down (except for CY14MX064Q1B). On power-up, data is restored to the SRAM from the nonvolatile memory (RECALL operation). You can also initiate the STORE and RECALL operations 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.
