The Analog Devices DS1744W-120+ is a non-volatile timekeeping RAM that integrates a Real-Time Clock (RTC), NV SRAM, crystal, and power-fail control circuit. It offers Y2K compliance and supports leap years, ensuring accurate timekeeping up to the year 2100.
This device features a parallel interface for accessing clock registers identically to static RAM. It operates with a supply voltage range of 2.97V to 3.63V and consumes approximately 2mA at 3.3V. The integrated 32KB NV SRAM provides data retention without external power.
The DS1744W-120+ is supplied in a 28-pin EDIP through-hole package, suitable for direct board mounting. Its operating temperature range is 0°C to 70°C, making it appropriate for standard commercial applications. The device also includes features like power-fail write protection and a battery voltage-level indicator flag.
The operating voltage for the DS1744W-120+ is 3.3V, with a supply range of 2.97V to 3.63V.
The DS1744W-120+ is available in a 28-EDIP package and a 28-DIP Module (0.600", 15.24mm).
The operating temperature range for the DS1744W-120+ is 0°C to 70°C.
Key features include integrated NV SRAM and Real-Time Clock, Y2K compliance with automatic leap-year compensation, 3.3V operation, 32KB memory size, and a parallel interface.
