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.  
Full featured Real Time Clock  
Watchdog timer  
Clock alarm with programmable interrupts
