Maxim Integrated DS1245WP-150 Nonvolatile SRAM

The Maxim Integrated DS1245WP-150 is a robust, high-performance 1024k Nonvolatile SRAM designed to deliver reliable data retention while eliminating the complexities, overhead, and system level reliability problems caused by battery-backed SRAM. With an access time of 150ns, it provides the high-speed data access expected from volatile SRAM, coupled with the non-volatility of EEPROM.

This innovative memory solution combines a fully static nonvolatile SRAM, a control circuit, and Lithium energy source which ensures data integrity and retains data in the absence of an external power supply. The DS1245WP-150 is specifically designed for a wide array of applications that require long-term data retention, such as data collection devices, industrial controllers, and mission-critical systems, where the preservation of data is paramount.

Key features of the DS1245WP-150 include:

• Integrated Power-Fail Deselect Circuitry: This feature automatically switches to the onboard battery when external power fails, ensuring data preservation without any user intervention.
• Write Protection: The device includes a write protect feature that, when enabled, prevents accidental data alteration during power transitions.
• Low Energy Consumption: The DS1245WP-150 is designed for low power consumption, helping to extend the life of the onboard battery and reduce the overall power requirements of the system it is used in.
• High Reliability: Data is maintained for over 10 years in the absence of power, making it an incredibly reliable choice for critical applications.
• Easy Integration: The 32-pin JEDEC standard 600-mil EDIP package allows for easy integration into a variety of system designs without the need for additional hardware or complex firmware.

The DS1245WP-150 operates over an industrial temperature range (-40°C to +85°C), making it suitable for use in environments with extreme temperatures. Its nonvolatility and durability make it an ideal choice for applications that not only require fast and unlimited read/write cycles but also must safeguard data against unexpected power outages.

With Maxim Integrated's reputation for quality and reliability, the DS1245WP-150 Nonvolatile SRAM is a secure and maintenance-free memory solution that meets the needs of demanding industrial applications.
