Maxim Integrated DS1218S+TR: SmartSocket 256k Nonvolatile SRAM Controller

The DS1218S+TR from Maxim Integrated is a high-performance SmartSocket Controller designed to offer nonvolatile data retention for 256k SRAMs. This innovative controller integrates a precision power-monitoring circuit, a lithium energy source, and a control circuitry in a single chip, ensuring that SRAMs maintain their data integrity during power loss or power-down conditions.

Ideal for applications requiring reliable and long-term data retention without battery maintenance, the DS1218S+TR is perfect for use in a wide range of industries, including telecommunications, computing, medical, and industrial controls. The controller is engineered to automatically switch to the backup energy source in the event of a power failure, seamlessly maintaining the SRAM's contents.

The DS1218S+TR comes in a compact surface-mount package, making it suitable for space-constrained applications. Its compatibility with JEDEC standard 28-pin 600-mil SOICs allows it to be easily integrated into existing designs without the need for significant board rework. The device operates over a wide temperature range, ensuring performance and reliability in diverse operating environments.

Key features of the DS1218S+TR include:

• Automatic battery backup for 256k x 8 SRAMs
• Integrated power-fail detection and write-protection circuitry
• Unconditionally write-protects memory when VCC is out of tolerance
• Reduces system complexity and component count
• Compatible with JEDEC standard 256k SRAMs
• Wide operating temperature range
• Surface-mount package for easy integration

The DS1218S+TR is not only a powerful component for safeguarding data but also a testament to Maxim Integrated's commitment to providing innovative and robust memory solutions. This SmartSocket Controller is a must-have for any application where data integrity and reliability are paramount.
