Product Overview: DS1743WP-150 from Maxim Integrated

The DS1743WP-150 is a high-quality, nonvolatile memory module designed and manufactured by Maxim Integrated. This robust product is an ideal solution for systems that require reliable data retention upon power loss, without the need for an external battery. The DS1743WP-150 integrates a full-function real-time clock (RTC), SRAM, power-fail control circuit, and lithium energy source into a compact 34-pin PowerCap Module (PCM).

Key Features

• Nonvolatile Timekeeping: The DS1743WP-150 features an RTC that maintains seconds, minutes, hours, day, date, month, and year information, with automatic leap year compensation valid up to 2100.
• Integrated Power Source: It includes a self-contained energy source that ensures data retention and clock functionality for over 10 years in the absence of external power.
• High-Speed SRAM: With 64KB of static RAM, it provides ample storage for critical data that must be preserved during power loss.
• Power-Fail Control: The module automatically switches to its internal lithium battery when a power-fail event is detected, ensuring data integrity and clock operation.
• Industrial Temperature Range: The device operates effectively over an industrial temperature range of -40°C to +85°C, making it suitable for harsh environments.
• Surface-Mountable: The PowerCap Module allows for direct surface mounting to a printed circuit board, facilitating a secure and reliable connection for industrial applications.
