The Cypress CY14B256KA combines a 256-Kbit nonvolatile static RAM with a full featured real time clock in a monolithic integrated circuit. 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。The SRAM is read and written an infinite number of times, while independent nonvolatile data resides in the nonvolatile elements.
The real time clock 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.
