S-35199A01-HRT1

Real Time Clock Overview

The S-35199A01-HRT1 is a Real Time Clock (RTC) integrated circuit manufactured by ABLIC Inc. It provides clock and calendar functions via a 3-wire serial interface. The device supports alarm capabilities and leap year adjustments. It operates with a time format of HH:MM:SS in either 12-hour or 24-hour modes. The component is housed in a compact 12-UFBGA, WLBGA package.

Real Time Clock Feature Summary

• Supports 3-wire serial communication for space-constrained designs
• Includes hardware alarm functionality
• Automatically handles leap year calculations

Real Time Clock Applications

• Compact electronic devices requiring precise timekeeping
• Systems utilizing 3-wire serial interfaces
• Applications needing automated leap year adjustment

Real Time Clock Procurement Notes

Verify the specific ordering suffix HRT1 to confirm the package type and tape/reel configuration. Ensure compatibility with the required 3-wire serial protocol and voltage levels. Confirm that the 12-UFBGA footprint matches the target PCB design constraints.

Real Time Clock Selection Notes

Select this component when a small form factor RTC is required. The 3-wire interface reduces pin count compared to standard I2C or SPI alternatives. Consider the WLBGA package for applications with strict size limitations.

Real Time Clock Part Context

This part belongs to ABLIC's line of real-time clock ICs designed for low-pin-count applications. It integrates calendar and timekeeping functions into a single compact package suitable for portable and embedded systems.

Real Time Clock Replacement Considerations

Check for direct substitutes within the S-35199 series from ABLIC. Verify pinout and interface compatibility before replacing with other RTC brands.
