STK17TA8  
128k X 8 AutoStore™ nvSRAM  
with Real Time Clock  
Features  
Description  
nvSRAMCombinedwithIntegratedRealTimeClockFunctions  
(RTC, Watchdog Timer, Clock Alarm, Power Monitor)  
The Cypress STK17TA8 combines a 1 Mb nonvolatile static RAM  
(nvSRAM) with a full featured real time clock in a reliable,  
monolithic integrated circuit.  
Capacitor or Battery Backup for RTC  
25, 45 ns Read Access and Read/Write Cycle Time  
Unlimited Read/Write Endurance  
The 1 Mb nvSRAM is a fast static RAM with a nonvolatile  
Quantum Trap storage element included with each memory cell.  
The SRAM provides the fast access and cycle times, ease of use  
and unlimited read and write endurance of a normal SRAM. Data  
transfers automatically to the nonvolatile storage cells when  
power loss is detected (the STORE operation). On power up,  
data is automatically restored to the SRAM (the RECALL  
operation). Both STORE and RECALL operations are also  
available under software control.  
Automatic nonvolatile STORE on Power Loss  
Nonvolatile STORE Under Hardware or Software Control  
Automatic RECALL to SRAM on Power Up  
Unlimited RECALL Cycles  
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  
minutes, hours, or days alarms. There is also a programmable  
watchdog timer for processor control.  
200K STORE Cycles  
20-Year nonvolatile Data Retention  
Single 3 V +20%, -10% Power Supply
