The Cypress CY14B256KA combines a 256-Kbit nonvolatile

static RAM with a full featured real time clock 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

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.
