PRELIMINARY  
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 can be 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  
STOREtoQuantumTrapinitiatedbysoftware, devicepin,  
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 @55°C  
• 10 mA typical ICC at 200 ns cycle time  
• Single 3V operation +20%, –10%  
• Commercial and industrial temperature  
• SSOP package (ROHS compliant)
