CY14B101K  
1 Mbit (128K x 8) nvSRAM With Real Time Clock  
Features  
Functional Description  
Data integrity of Cypress nvSRAM combined with full featured  
Real Time Clock (RTC)  
The Cypress CY14B101K combines a 1 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 an infinite  
number of times, while independent, nonvolatile data resides in  
the nonvolatile elements.  
Watchdog timer  
Clock alarm with programmable interrupts  
Capacitor or battery backup for RTC  
25 ns, 35 ns, and 45 ns access times  
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 alarm or  
periodic seconds, minutes, hours, or days. There is also a  
programmable watchdog timer for process control.  
Hands off automatic STORE on power down with only a small  
capacitor  
STORE to QuantumTrap™ initiated by software, device pin, or  
on power down  
RECALL to SRAM initiated by software or on power up  
Infinite READ, WRITE, and RECALL cycles  
High reliability  
Endurance to 200,000 cycles  
Data retention: 20 years at 55°C  
10 mA typical ICC at 200 ns cycle time  
Single 3V operation +20%, –10%  
Commercial and industrial temperature  
SSOP package (ROHS compliant)
