功能描述

The Cypress CY14B101KA/CY14B101MA combines a 1-Mbit nvSRAM 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.
