Functional Description  
RECALL to SRAM initiated by software or power up  
High reliability  
The Cypress CY14B104KA/CY14B104MA combines a 4-Mbit  
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 infinite number of times, while independent nonvolatile  
data resides in the nonvolatile elements.  
Infinite read, write, and recall cycles  
200,000 STORE cycles to QuantumTrap  
20 year data retention  
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 one time alarms or periodic  
seconds, minutes, hours, or days. There is also a programmable  
watchdog timer for process control.  
Single 3V +20%, –10% operation  
Data integrity of Cypress nvSRAM combined with full featured  
Real-Time-Clock
