The Maxim Integrated DS1314E+ is a state-of-the-art nonvolatile controller designed to maintain the integrity of data in the event of a power failure. This advanced component ensures that data is safely transferred from SRAM to nonvolatile storage when a power loss is detected, and automatically restores it once power is reinstated.

Key Features

• Automatic Backup and Restore: The DS1314E+ automatically switches to the backup battery when main power is lost and initiates a nonvolatile backup or restore operation, ensuring data protection and reliability.
• Write Protection: Includes a precision power-monitoring circuit that write-protects memory when VCC falls below a factory-set threshold, preventing data corruption.
• Low Power: Designed for energy efficiency, it operates with a low standby current, making it ideal for battery-backed applications.
• Wide Operating Range: Functions over a wide voltage range of 2.0V to 5.5V, providing flexibility across various power supply specifications.
• Surface-Mount Package: Available in a compact, surface-mount package, the DS1314E+ is suitable for space-constrained applications.

Applications

The DS1314E+ is versatile and can be used in a variety of applications where data integrity during power loss is crucial. This includes:

• RAID systems
• Industrial controllers
• POS terminals
• Telecommunications equipment
• Medical monitoring devices

Technical Specifications

With a robust set of technical specifications, the DS1314E+ is designed to meet the needs of demanding applications. It features:

• Direct connection to SRAM
• Redundant nonvolatile controller for high reliability
• Automatic chip deselect when VCC falls below the minimum VCC threshold
• Industrial temperature range (-40°C to +85°C)
• 20-Pin (300 mils) SO package

Maxim Integrated's DS1314E+ nonvolatile controller is a reliable solution for systems that cannot afford data loss during power failures.
