赛普拉斯 CY14B104K 和 CY14B104M 将 4 Mbit 的非易失性静态 RAM (nvSRAM) 和功能齐全的 RTC 整合在了一个单片集成电路中。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,而独立的非易失性数据则存储在非易失性组件中。

The RTC function provides an accurate clock with leap year tracking and a programmable, high accuracy oscillator. The alarm function is programmable for periodic minutes, hours, days, or months alarms. There is also a programmable watchdog timer for process control.

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. 

Reliability and business continuity are of utmost importance for us. Hence, we remain fully committed to honoring existing customer and distributor relationships. This includes offering the legacy Cypress product portfolio. We thank you very much for your trusting support.
