STK17TA8 is a 128K x 8 AutoStore™ nvSRAM event data recorder with Real-Time Clock that combines the data integrity of Simtek nvSRAM with a full-featured RTC.
The Simtek STK17TA8 is an integrated circuit combining a 1 Mbit nonvolatile static RAM (nvSRAM) with a full-featured real-time clock. It utilizes Simtek's QuantumTrap™ technology to ensure reliable data storage, allowing the SRAM to be read and written unlimited times while independent nonvolatile data resides in dedicated elements.
The device supports operation at 3V (+20%, -10%) and offers access times of 25ns, 35ns, or 45ns. Key features include a programmable alarm function, a watchdog timer for process control, and capacitor or battery backup options to maintain the RTC supply voltage during power loss.
