Real Time Clock datasheet and documents for DS1501YN+

DS1501YN+

Real Time Clock Overview

The DS1501YN+ is a Y2K-compliant real-time clock/calendar IC manufactured by Analog Devices Inc./Maxim Integrated. It features a parallel interface, 256 bytes of battery-backed NV SRAM, and operates within a voltage range of 4.5V to 5.5V. The device provides century, year, month, date, day, hours, minutes, and seconds data in 24-hour BCD format with automatic leap-year compensation valid up to the year 2100. It includes a programmable watchdog timer, RTC alarm, power-on reset, and battery monitors. The component is housed in a 28-pin PDIP package and supports an operating temperature range from -40°C to +85°C.

Real Time Clock Procurement Notes

Verify the specific suffix 'YN+' against the manufacturer's current ordering information to confirm lead-free status and package type. Confirm availability as distribution channels may vary. Ensure the parallel interface requirements match the target system design before procurement.

Real Time Clock Selection Notes

Select the DS1501YN+ when a parallel interface and high-capacity NV SRAM are required alongside precise timekeeping. Ensure the system power supply aligns with the 4.5V to 5.5V operating range. Consider the 28-pin PDIP package constraints for PCB layout and thermal management within the specified industrial temperature range.

Real Time Clock Part Context

The DS1501 series comprises full-function RTCs designed for applications requiring robust timekeeping and data retention. The DS1501 variant specifically refers to the chip-only version, distinct from the DS1511 module which includes an embedded battery and crystal. This part belongs to the Maxim Integrated line now under Analog Devices.
