Real Time Clock datasheet and documents for DS1501Y

DS1501Y

Real Time Clock Overview

The DS1501Y is a Y2K-compliant real-time clock/calendar integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It features a parallel byte-wide interface, 256 bytes of battery-backed NVSRAM, and operates at +5V (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. Key electrical parameters include an active supply current of 15mA maximum at 5V, a standby current of 5mA maximum, and a battery voltage range of 2.5V to 3.7V. It includes a programmable watchdog timer, RTC alarm, power-on reset, and battery monitors.

Real Time Clock Procurement Notes

Verify the specific package variant when ordering, as the DS1501 family includes TSOP, EDIP, and DIP modules. Confirm lead-free status via the '+' suffix if required. Check for available errata documentation on the manufacturer's website prior to final design implementation.

Real Time Clock Selection Notes

Select the DS1501Y for systems requiring a standalone +5V RTC with parallel access. Ensure the external crystal matches the specified load capacitance (6pF or 12.5pF) and configure the CS bit accordingly. Verify that the system power supply remains within the 4.5V to 5.5V range during active operation.

Real Time Clock Part Context

The DS1501/DS1511 series consists of full-function RTCs. The DS1501 is the chip version available in various packages, while the DS1511 is a stand-alone encapsulated module with an embedded battery and crystal. Both share identical register maps and functional capabilities.
