Integrated Non-Volatile Memory & Timekeeping

The DS1245Y-100 combines high-density SRAM with a built-in real-time clock and a lithium backup cell in a single compact module. Designed for durability, it retains both memory and accurate timekeeping for at least 10 years, making it ideal for applications where data preservation and timestamping are essential.

Industry-Standard Compatibility & Easy Integration

With its 128K x 8 organization and parallel address/data bus, the DS1245Y-100 is configured to match industry-standard SRAM pinouts. Its DIP-32 form factor allows for straightforward through-hole PCB mounting, ensuring ease of replacement and compatibility with existing systems.

Reliable Performance for Critical Applications

Operating between 0C and +70C, the DS1245Y-100 supports demanding industrial environments. The module features fast 100 ns access, low standby current, and a robust RTC with 2 minutes per month accuracy at 25C, providing reliable performance for data logging, instrumentation, and time-sensitive processes.

FAQs of DS1245Y-100:

Q: How does the DS1245Y-100 retain data and time information during power loss?

A: The DS1245Y-100 features a built-in lithium cell that automatically powers the SRAM and real-time clock when external supply is lost, maintaining both stored data and time information for up to 10 years, ensuring reliability without the need for external backup circuitry.

Q: What applications benefit most from using the DS1245Y-100 module?

A: Applications that require non-volatile data retention and precise timekeeping, such as industrial automation, instrumentation, and data logging systems, benefit greatly from the DS1245Y-100s integrated memory and RTC features. Its reliability and long battery backup make it suitable for time- and date-stamped data storage.

Q: When should the DS1245Y-100 be considered in a project design?

A: The DS1245Y-100 is ideal when a project demands seamless non-volatile memory with integrated timekeeping, especially in applications where power loss can occur. Use it during initial design or when upgrading legacy systems for enhanced reliability and minimal maintenance.

Q: Where is the DS1245Y-100 typically installed in electronic systems?

A: This device is mounted using through-hole technology, fitting securely in any PCB that supports a 32-pin DIP socket. It is commonly found in industrial controllers, data acquisition modules, and electronic record-keeping devices.

Q: What is the process for interfacing with the DS1245Y-100s memory and RTC functions?

A: With its parallel address/data bus and industry-standard pinout, the DS1245Y-100 is easily linked to microcontrollers or logic circuits. Standard SRAM read/write timing applies, and dedicated registers allow for RTC configuration and retrieval.

Q: How does the DS1245Y-100 contribute to system longevity and maintenance reduction?

A: By offering a 10-year minimum data and time retention from its integrated battery, the DS1245Y-100 significantly reduces the frequency of maintenance and the risks associated with memory loss, supporting long-lasting, low-intervention system operation.
