Real Time Clocks Analog Devices, Inc. DS1747WP-120+ Overview
The DS1747WP-120+ from Analog Devices, Inc. is a high-performance integrated circuit specifically designed for real-time clock (RTC) and calendar applications. This precision device ensures reliable timekeeping with a complete clock calendar functionality including seconds, minutes, hours, day, date, month, and year information, which automatically adjusts for months with fewer than 31 days, including corrections for leap year. Encased in a robust 34-pin PCM package, the DS1747WP-120+ also integrates battery-backed non-volatile (NV) SRAM, making it an ideal choice for maintaining accurate time and settings in a variety of applications, particularly when power consistency is an issue.
DS1747WP-120+ Features
The DS1747WP-120+ includes numerous features that make it highly suitable for complex applications that require accurate timekeeping and data integrity. Key features include:
- Integrated battery backup to preserve clock and calendar data and settings.
- Automatic leap year compensation valid up to 2100.
- 34-pin PowerCap Module (PCM) package ensuring durability and ease of integration.
- Low energy consumption, enhancing its utility in battery-driven devices.
- Serial real-time clock, which utilizes minimal power for full clock/calendar functionality.
