Functional Description

❐

STORE to QuantumTrap nonvolatile elements is initiated by

software, hardware, or AutoStore on power down

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 incor-

porate 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.

❐

RECALL to SRAM initiated on power up or by software

■

High Reliability

❐

Infinite Read, Write, and RECALL cycles

1 Million STORE cycles to QuantumTrap

20 year data retention

Real Time Clock

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.
