Real Time Clock datasheet and documents for DS1511W+

DS1511W+

Real Time Clock Overview

The DS1511W+ is a Y2K-compliant real-time clock/calendar integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 3.0V to 3.6V and supports an operating temperature range of 0°C to +70°C. The device features a parallel interface, providing access to timekeeping registers in 24-hour BCD format alongside 256 bytes of battery-backed NV SRAM. Key specifications include automatic leap-year compensation valid up to the year 2100, programmable watchdog timer functionality, and precision power-on reset circuitry. The component is housed in a 28-pin EDIP module package designed for through-hole mounting.

Real Time Clock Procurement Notes

Verify that the specific ordering suffix corresponds to the required voltage and package configuration. Confirm RoHS compliance status and lead-free designation as indicated by the '+' symbol. Ensure the selected variant matches the intended operational temperature range and interface requirements before finalizing procurement orders.

Real Time Clock Selection Notes

Select the DS1511W+ when a standalone encapsulated DIP module with embedded battery and crystal is required. This model is suitable for applications needing a 3.3V supply and through-hole installation. Verify compatibility with systems requiring parallel bus interfaces and dedicated alarm or watchdog timer functionalities.

Real Time Clock Part Context

The DS1511W+ belongs to the DS1501/DS1511 family of Y2K-compliant watchdog real-time clocks. Unlike the DS1501 series which requires external components, the DS1511 integrates the battery and crystal directly into the encapsulated module. This simplifies design implementation while maintaining full register accessibility via a byte-wide parallel interface.
