Functional Description  
High reliability  
The Cypress CY14B101KA/CY14B101MA combines a 1-Mbit  
nvSRAM 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.  
Infinite Read, Write, and RECALL cycles  
1 million STORE cycles to QuantumTrap  
20 year data retention  
Real time clock (RTC)  
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)  
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.
