The DS1747WP-120+ is a highly reliable, non-volatile RAM (NVRAM) integrated circuit (IC) component. It is manufactured by Maxim Integrated, a well-known company specializing in analog and mixed-signal semiconductors.
Overview:
The DS1747WP-120+ provides a combination of CMOS and NMOS circuits to form a non-volatile SRAM (NVSRAM) with a real-time clock/calendar (RTC) functionality. This IC is designed to retain data without any power supply and offers high-speed access to memory.
Key features:
1. Non-volatile storage: The DS1747WP-120+ utilizes the NVSRAM architecture, enabling it to store data even in the absence of power. It combines the benefits of both volatile and non-volatile memory by employing an integrated lithium coin cell battery backup and a backup power-fail detection circuit.
2. Real-time clock/calendar: The integrated RTC provides highly accurate timekeeping capabilities with a built-in oscillator circuit and a 32-bit counter. The RTC component supports leap years and offers a clock accuracy of ±2 minutes per month.
3. High-speed access: The IC component provides fast access times to the memory, offering access times as low as 45ns. This feature makes it suitable for applications requiring quick data retrieval and storage.
4. Low power consumption: The DS1747WP-120+ is designed to minimize power consumption, making it suitable for battery-powered devices
