The DS1553-100+ is a high-precision, full-featured timekeeping RAM designed by Maxim Integrated that combines a binary counter and 64KB of nonvolatile static RAM. It is engineered to provide a complete solution for timekeeping and memory storage in a wide array of applications, including telecommunications, networking, industrial systems, and data-logging.

This versatile component is more than just a clock or memory chip; it integrates a real-time clock/calendar and a power-fail control circuit into a single package, ensuring that timekeeping and data retention are maintained even in the event of a power loss. The DS1553-100+ operates in a wide voltage range and features a long-life battery, which is included in the module to provide years of uninterrupted operation.

Key Features:

• Real-Time Clock/Calendar: Tracks time in seconds, minutes, hours, days, date, month, and year, with leap-year compensation valid up to the year 2100.
• Nonvolatile Memory: 64KB of static RAM preserves data with no power supply for over 10 years.
• Automatic Power-Fail Chip Deactivation: When VCC falls below a certain threshold, the device automatically switches to battery backup mode, protecting the clock and RAM data.
• Programmable Watchdog Timer: A safeguard feature that can be set to reset the system if the software becomes unresponsive.
• Programmable Alarm: Can be set to trigger on a specific minute, hour, day, or date, providing versatile scheduling capabilities.
• Industrial Temperature Range: Operates reliably in environments ranging from -40°C to +85°C.
• Simple Integration: Encased in a 28-pin EDIP or surface-mount package, it is easy to integrate into existing designs.

The DS1553-100+ is a durable and reliable choice for systems that require accurate timekeeping and data integrity through power cycles. With its integrated battery backup and robust feature set, this product is an ideal selection for critical applications where maintaining accurate time and data is paramount.

Whether you are designing a new system or upgrading an existing one, the DS1553-100+ from Maxim Integrated provides the performance and reliability needed for your timekeeping and memory storage needs.
