The Maxim Integrated DS1747WP-120IND is a robust, full-featured nonvolatile timekeeping RAM that combines a binary counter, a 64-byte NV SRAM control area, and 2K x 8 NV SRAM into a single device. Designed for industrial applications, it operates at a voltage range of 2.7V to 3.6V and includes an integrated crystal and a lithium energy source that can maintain data and real-time clock operations for over 10 years in the absence of external power.

This device is specifically engineered to withstand harsh industrial environments with its wide operating temperature range of -40°C to +85°C. The DS1747WP-120IND is encapsulated in a power-cap package which provides a high level of protection against environmental factors such as moisture and contaminants, making it an ideal choice for mission-critical systems where data integrity and reliability are paramount.

Key features of the DS1747WP-120IND include:

• Integrated, factory-sealed crystal and battery
• 10 years of minimum data retention in the absence of external power
• Real-time clock (RTC) counts seconds, minutes, hours, day, date, month, and year with leap-year compensation valid up to 2100
• 128 bytes of user-accessible nonvolatile memory for control/configuration data
• 2K x 8 nonvolatile static RAM for user-defined data storage
• Programmable alarm and interrupt function for system wake-up on demand
• Automatic power-fail chip deselect and write-protection
• Industrial temperature range (-40°C to +85°C) suitable for harsh environments

The DS1747WP-120IND is particularly suitable for applications that require long-term data retention and accurate timekeeping even in the absence of power, such as embedded systems, utility meters, industrial controllers, point-of-sale terminals, and medical devices. Its integration of memory, real-time clock, and power source in a single package simplifies design, reduces board space requirements, and enhances overall system reliability.

Maxim Integrated's commitment to quality and reliability is evident in the DS1747WP-120IND, making it a trusted component for industrial applications that cannot afford to compromise on performance.
