DS1315S-5+

Overview

The DS1315S-5+ is a Phantom Time Chip combining a CMOS real-time clock and nonvolatile memory controller. It tracks hundredths of seconds, time, date, and year with automatic leap year correction up to 2100. The device operates at +5V (4.5V to 5.5V) in the commercial temperature range (0°C to +70°C). Communication uses a serial bit stream pattern recognition protocol without requiring address space. It supports battery backup for external SRAM via redundant BAT1/BAT2 inputs and provides power-fail detection with write protection.

Feature Summary

Phantom Time Chip interface using 64-bit serial pattern recognition
Automatic leap year correction valid through 2100
Nonvolatile SRAM controller with redundant battery switching
Power-fail detection and write protection circuitry

Applications

Systems requiring nonvolatile timekeeping without address bus overhead
Applications needing battery-backed SRAM management
High-reliability systems utilizing redundant battery attachment

Procurement Notes

Verify the package marking 'DS1315 56' to confirm the specific variant. Ensure the design accommodates the 16-pin SO (300 mils) footprint. Confirm that the system voltage remains within the 4.5V to 5.5V range for this specific part number.

Selection Notes

Select this component when a dedicated address bus for RTC communication is unavailable or undesirable. The 64-bit pattern recognition method eliminates address conflicts. Verify that the application environment stays within the 0°C to +70°C commercial temperature limit; use the industrial variant for wider ranges.

Part Context

This part belongs to the DS1315 family of Phantom Time Chips. The 'S' suffix indicates the 16-pin Small Outline package. The '-5+' designation specifies the +5V operating voltage and lead-free/RoHS-compliant construction. Other variants include PDIP and TSSOP packages with different voltage or temperature ratings.

Replacement Considerations

Direct pin-compatible replacements within the same package and voltage require checking the ordering information table. Variants like DS1315N-5+ offer the same electrical characteristics but with an extended industrial temperature range (-40°C to +85°C).
