Maxim Integrated DS1330WP-100+ Overview

The DS1330WP-100+ from Maxim Integrated is a high-performance, nonvolatile (NV) SRAM with a storage capacity of 256k x 8 bits. This memory device combines the access speed of SRAM with the nonvolatility of EEPROM, ensuring data retention without the need for a battery backup in the event of power loss. It is particularly well-suited for applications requiring frequent or rapid data updates, where the risk of data corruption due to power failure must be minimized.

Key Features

• Integrated Power-Fail Deselect Circuitry: The DS1330WP-100+ includes automatic power-fail chip deselect circuitry which switches to nonvolatile mode during a power failure, ensuring data integrity.
• High-Speed Read and Write Operations: With fast access times, the device provides the high-speed read and write operations of traditional SRAM, making it ideal for real-time applications.
• Unlimited Write Cycles: Unlike EEPROM, the DS1330WP-100+ allows for unlimited write cycles, enhancing its endurance and reliability for write-intensive applications.
• Nonvolatility: The device's nonvolatile elements ensure that data is retained for over 10 years without the need for an external battery.
• Low-Power Operation: It is designed for low-power consumption, making it suitable for battery-powered and portable devices.

Applications

The DS1330WP-100+ is ideal for a wide range of applications, including:

• RAID systems
• Industrial controls
• Networking equipment
• Medical devices
• Aerospace and defense systems

Technical Specifications

• Memory Size: 256k x 8 bits
