128Kx8 Autostore nvSRAM With Real-Time Clock FEATURES nvSRAM Combined With Integrated Real-Time Clock Functions (RTC, Watchdog Timer, Clock Alarm, Power Monitor) Capacitor or Battery Backup for RTC 25, 45 ns Read Access & R/W Cycle Time Unlimited Read/Write Endurance 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 20-Year Non-volatile Data Retention Single 3 V +20%, -10% Power Supply Commercial and Industrial Temperatures 48-pin 300-mil SSOP Package (RoHS-Compliant) STK17TA8 DESCRIPTION The Simtek STK17TA8 combines a 1Mb non-volatile static RAM (nvSRAM) with a full-featured real-time clock in a reliable, monolithic integrated circuit. The 1Mbit nvSRAM is a fast static RAM with a nonvolatile Quantum Trap storage element included with each memory cell. 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. 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, o……
