Quality Control: Learn More
The Analog Devices Inc./Maxim Integrated DS1251W-120IND is a 512KB Parallel Phantom Time Chip, designed for robust timekeeping applications. This electronic component features an internal Real Time Clock (RTC) with a 32-DIP Module (0.600", 15.24mm) package, suitable for through-hole mounting. Key functionalities include leap year support and non-volatile SRAM for data retention. The interface operates in parallel, with time formats supporting HH:MM:SS:hh (12/24 hr) and date formats of YY-MM-DD-dd. Operating within a temperature range of -40°C to 85°C, it requires a supply voltage between 2.97V and 3.63V, with a typical timekeeping current draw of 7mA at 3.3V. This device is commonly integrated into industrial control systems, data logging equipment, and telecommunications infrastructure.
