Functional Description

The Cypress CY14B108K/CY14B108M combines a 8-Mbit

nonvolatile static RAM (nvSRAM) with a full featured RTC in a

monolithic integrated circuit. The embedded nonvolatile

elements incorporate QuantumTrap technology producing the

world’s most reliable nonvolatile memory. The SRAM is read and

written infinite number of times, while independent nonvolatile

data resides in the nonvolatile elements.

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.
