DS17285S-3/T&R

Real Time Clock Overview

The DS17285S-3+ is a Real-Time Clock (RTC) integrated circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features a multiplexed parallel interface and includes 2 kB of non-volatile static RAM (NVSRAM). The device supports calendar and clock functions with date formats of YY-MM-DD-dd and time formats of HH:MM:SS in 24-hour mode. It operates within a supply voltage range of 2.7 V to 3.7 V and is housed in a 24-pin SOIC package. The component is designed for surface-mount installation and functions within an operating temperature range of 0°C to +70°C.

Real Time Clock Procurement Notes

Verify the specific suffix against manufacturer documentation, as standard availability may vary. Confirm RoHS compliance status through official datasheets or certification declarations prior to integration. Ensure the selected variant matches the required voltage and interface specifications for the target application design.

Real Time Clock Selection Notes

Select this component when a parallel interface is required alongside significant onboard storage for real-time applications. The 2.7 V to 3.7 V operating range suits low-voltage digital systems. Verify that the 24-pin SOIC footprint aligns with the PCB layout constraints and that the commercial temperature range meets environmental requirements.

Real Time Clock Part Context

This part belongs to the DS17285 series of real-time clocks from Maxim Integrated. These devices are engineered to provide accurate timekeeping and substantial non-volatile memory in a single package, facilitating simplified system designs for embedded applications needing both RTC and SRAM functionalities.

Real Time Clock Replacement Considerations

Consult official cross-reference guides for verified substitutes. Ensure any replacement maintains compatibility with the multiplexed parallel interface and provides equivalent NVSRAM capacity.
