DS2404S-001

Real Time Clock Overview

The DS2404S-001 is a Real-Time Clock (RTC) IC and binary counter manufactured by Analog Devices Inc./Maxim Integrated. It features 512 bytes of SRAM and communicates via the 1-Wire interface. The device operates on a supply voltage ranging from 2.8V to 5.5V, with a maximum current consumption of 500µA at 5V. It is housed in a 16-SOIC package (0.295 inch width) and supports an operating temperature range of -40°C to 85°C. Key functional characteristics include alarm capabilities, square wave output, and binary time formatting.

Real Time Clock Procurement Notes

Verify component authenticity due to discontinued status. Confirm RoHS compliance requirements as the part is listed as non-compliant. Check for valid manufacturer documentation to ensure pinout and electrical specifications match design needs before integration.

Real Time Clock Selection Notes

Select this component when a combined RTC and memory solution is required on a single 1-Wire bus. Ensure the system voltage aligns with the 2.8V to 5.5V operational range. Consider the 16-SOIC footprint for PCB layout constraints and verify that binary time format compatibility exists with the host processor.

Real Time Clock Part Context

This part belongs to the EconoRAM series from Maxim Integrated. It serves as a specialized peripheral for microcontroller systems needing time-stamping and volatile/non-volatile data retention without complex parallel interfaces. The 'S' suffix typically denotes the SOIC package variant within the DS2404 family.
