DS1243Y-120+

Overview

The DS1243Y-120+ is a phantom time chip manufactured by Analog Devices Inc./Maxim Integrated, designed for real-time clock applications. It features a parallel interface and operates within a supply voltage range of 4.5V to 5.5V. The device supports both 12-hour and 24-hour time formats (HH:MM:SS:hh) and utilizes a YY-MM-DD-dd date format. Key functional capabilities include leap year compensation. It draws a maximum current of 7mA at 3.3V during timekeeping operations. The component is housed in a 28-EDIP package with through-hole mounting and functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

Phantom Time Chip architecture for seamless RTC integration
Parallel interface supporting standard timing protocols
Leap year compensation functionality
Dual time format support: HH:MM:SS:hh (12/24 hr)

Applications

Real-time clock modules requiring phantom chip compatibility
Industrial systems needing Y2K-compliant date tracking
Embedded devices utilizing parallel bus architectures

Procurement Notes

Verify the specific suffix 'Y' indicates the commercial temperature grade (0°C to +70°C) as per manufacturer documentation. Confirm that the 28-EDIP package dimensions match the target PCB footprint. Ensure the design accounts for the parallel interface requirements and the specified 4.5V to 5.5V supply voltage constraints for proper operation.

Selection Notes

Select this component when a phantom RTC chip is required instead of a full smart socket module. The DS1243Y-120+ is suitable for designs where space is limited compared to larger RTC packages but a parallel interface is preferred over serial alternatives. Verify that the system power supply remains stable within the 4.5V to 5.5V range to ensure accurate timekeeping performance.

Part Context

This part belongs to the Maxim Integrated line of nonvolatile memory and real-time clock solutions. Phantom chips like the DS1243Y are designed to replace traditional battery-backed SRAM or EEPROMs in systems that require persistent time data without the complexity of managing external battery switching circuits directly on the main logic board.
