The STK11C88-S45I is a 64Kb nonvolatile static RAM (nvSRAM) manufactured by Cypress Semiconductor Corp. It's designed to provide the speed of SRAM with the non-volatility of EEPROM, combining these features to ensure data retention even when power is lost. This particular model has a slower access time than other models in the series.
Applications
- Data logging systems
- Industrial automation equipment
- Medical instrumentation
- Point-of-sale (POS) terminals
- Networking devices
Features
- 64Kb (8K x 8) memory organization
- SRAM-like read/write cycles with 45 ns access time
- Automatic nonvolatile STORE on power-down
- Software controlled STORE and RECALL functions
- Unlimited read and write cycles to SRAM
- 1 million STORE cycles to nonvolatile memory
- Data retention of 10 years minimum
- Single 5V power supply
- Industry-standard pinout
Benefits
- Data Security: Ensures data is preserved during power loss events.
- High Performance: Offers fast SRAM access times for quick data manipulation.
- Simplified System Design: Automatic STORE function eliminates the need for external circuitry.
- Long-Term Reliability: Guarantees data retention for a minimum of 10 years.
- Easy Integration: Standard pinout simplifies integration into existing systems.
Additional Details
The STK11C88-S45I is built utilizing Cypress's nonvolatile technology, integrating SRAM cells with nonvolatile SONOS (Silicon-Oxide-Nitride-Oxide-Silicon) memory elements. The automatic store feature copies the SRAM data to the nonvolatile memory array when power is lost, preventing data corruption. Software controlled STORE and RECALL allow for manual data backup and restoration. For detailed specifications, including timing diagrams, power consumption, and package information, refer to the Cypress Semiconductor datasheet for the STK11C88 series. Be sure to note the 'S45I' designation for specific performance characteristics and temperature range.
