Maxim Integrated DS1748D - Real-Time Clock with Embedded NV SRAM

The DS1748D from Maxim Integrated is a high-performance, low-power real-time clock (RTC) with an integrated 32KB NV SRAM. This product is specifically designed to provide a reliable timekeeping solution with the added benefit of non-volatile memory storage, making it ideal for applications that require data retention without a power supply.

This RTC is equipped with a built-in power-sense circuit that detects power failures and automatically switches to the backup energy source, ensuring uninterrupted operation and timekeeping. The DS1748D operates over a wide voltage range and features a programmable clock output for versatility in various system designs.

Key Features:

• Integrated NV SRAM: 32KB of non-volatile static RAM allows for data storage that is preserved even during power loss.
• Automatic Backup: The built-in power-fail detect circuit switches to the backup energy source, ensuring data and timekeeping integrity.
• Low Power Consumption: Designed for energy efficiency, the DS1748D is suitable for battery-powered applications.
• Programmable Clock Output: The RTC provides a programmable square-wave output for various clock requirements.
• Wide Operating Temperature Range: The device functions reliably across a broad temperature spectrum, making it suitable for harsh environments.
• Serial Interface: Easy integration with microprocessors through the industry-standard serial interface.
• Long-Term Reliability: With Maxim Integrated's commitment to quality, this RTC is designed for long-term dependable performance.

The DS1748D is housed in a 28-pin, 600-mil EDIP package, offering a compact footprint for space-constrained applications. Its non-volatile feature set makes it a perfect fit for systems that need to maintain settings, calibration data, log events, or any critical data during power loss events. Applications ranging from industrial control systems, network servers, to medical devices can benefit from the robust features of the DS1748D RTC with embedded NV SRAM.

Maxim Integrated's DS1748D provides a synchronized clock/calendar functionality and a secure memory storage solution in a single package, streamlining design efforts and reducing component count for system developers.
