Maxim Integrated DS1747W-120IND Nonvolatile Timekeeping RAM

The DS1747W-120IND is a high-performance, nonvolatile timekeeping RAM module developed by Maxim Integrated. This robust product integrates a full-function, binary-coded decimal (BCD) clock/calendar, 512K x 8 nonvolatile static RAM, power-fail control circuit, and battery into a single monolithic chip. Designed with precision and reliability in mind, the DS1747W-120IND is an ideal solution for demanding applications that require long-term data retention and timekeeping, even in the absence of power.

Featuring a durable industrial temperature range of -40°C to +85°C, the DS1747W-120IND is specifically tailored for use in harsh environments, making it perfect for industrial applications. The device is housed in a 34-pin PowerCap Module (PCM) which not only provides a direct connection to a motherboard but also supports surface-mount technology, enhancing its robustness and ease of integration into various systems.

Key attributes of the DS1747W-120IND include:

• Integrated Power-Fail Write Protection: Ensures that all data is nonvolatile and protected during power loss, preventing data corruption and loss.
• Real-Time Clock: Tracks seconds, minutes, hours, day, date, month, and year information with leap-year compensation valid up to the year 2100.
• Low Energy Consumption: Optimized for low power usage, which is critical for battery-backed memory and timekeeping devices.
• Battery Backup: Comes with a replaceable lithium battery, ensuring long-term reliability of the clock and data retention.
• Automatic Power-Fail Chip De-Select and Write-Protection: Activates during power transitions, safeguarding the memory contents.
• 512K x 8 Nonvolatile Static RAM: Offers ample storage for critical data that must be preserved during power outages.

The DS1747W-120IND from Maxim Integrated is more than just a memory chip; it's a comprehensive timekeeping solution that provides peace of mind for systems requiring consistent performance and data integrity under varying conditions. With its integrated features and industrial-grade design, the DS1747W-120IND stands out as a reliable component for mission-critical applications in fields such as telecommunications, networking, and industrial control systems.
