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

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.

❐ 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 (RTC)

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.

❐ Full-featured real time clock

❐ Watchdog timer

❐ Clock alarm with programmable interrupts

❐ Capacitor or battery backup for RTC

❐ Backup current of 0.35 µA (Typ)
