STK17TA8  
128Kx8 Autostore nvSRAM With Real-Time Clock  
DESCRIPTION  
FEATURES  
The Simtek STK17TA8 combines a 1Mb non-volatile  
static RAM (nvSRAM) with a full-featured real-time  
clock in a reliable, monolithic integrated circuit.  
• nvSRAM Combined With Integrated Real-Time  
Clock Functions (RTC, Watchdog Timer, Clock  
Alarm, Power Monitor)  
The 1Mbit nvSRAM is a fast static RAM with a non-  
volatile Quantum Trap storage element included  
with each memory cell.  
• Capacitor or Battery Backup for RTC  
• 25, 45 ns Read Access & R/W Cycle Time  
• Unlimited Read/Write Endurance  
The SRAM provides the fast access & cycle times,  
ease of use and unlimited read & write endurance of  
a normal SRAM. Data transfers automatically to the  
non-volatile 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 Non-volatile STORE on Power Loss  
• Non-Volatile STORE Under Hardware or Software  
Control  
• Automatic RECALL to SRAM on Power Up  
• Unlimited RECALL Cycles  
• 200K STORE Cycles  
The real time clock function provides an accurate  
clock with leap year tracking and a programmable,  
high accuracy oscillator. The Alarm function is pro-  
grammable for one-time alarms or periodic minutes,  
hours, or days alarms. There is also a programma-  
ble watchdog timer for processor control.  
• 20-Year Non-volatile Data Retention  
• Single 3 V + 20%, -10% Power Supply  
• Commercial and Industrial Temperatures  
• Small Footprint SSOP Package (RoHS-  
Compliant)
