Overview
The STK17TA8-RF35 is a non-volatile SRAM device manufactured by Simtek, featuring an AutoStore architecture that automatically transfers data from volatile SRAM to non-volatile memory upon power loss. The component provides a storage density of 128K x 8 bits with a maximum access time of 35 ns. It integrates a real-time clock (RTC) for timestamping events and includes a battery-backed voltage regulator to maintain RTC operation during main power failure. The device operates asynchronously and is designed for applications requiring reliable event logging and data retention without external backup power management.
Feature Summary
- AutoStore technology for automatic data preservation during power transitions
- Integrated real-time clock (RTC) with calendar and alarm functions
- 128K x 8 bit memory organization with 35 ns access speed
- Battery-backed voltage regulator for continuous RTC operation
Applications
- Event data recorders in industrial systems
- Power failure logging in telecommunications equipment
- Data acquisition systems requiring timestamped records
- Embedded controllers needing non-volatile configuration storage
Part Context
This part belongs to the STK17TA8 family of AutoStore nvSRAMs, which combines the speed of SRAM with the persistence of EEPROM or FRAM technologies. Unlike standard SRAM, it retains data without constant power, and unlike flash, it offers unlimited endurance cycles. The 'RF35' suffix typically denotes the package type and speed grade within the Simtek product line.
