DS1501WZ+ Description

Short technical summary and product information.

The DS1501WZ+ is a full-function, year 2000-compliant Real Time Clock/Calendar (RTC) from Analog Devices / Maxim Integrated. It operates within a voltage range of 2.5V to 3.7V and has a typical current draw of 4mA at 3V to 3.6V. This device is designed for surface mount applications and comes in a 28-SOIC package.

 

Key features include BCD-coded century, year, month, date, day, hours, minutes, and seconds with automatic leap-year compensation valid up to the year 2100. It also incorporates a programmable watchdog timer, an RTC alarm, precision power-on reset, and power-control circuitry. The DS1501WZ+ includes 256 bytes of battery-backed NV SRAM and a 32.768kHz output. The interface is parallel, and the time format is 24-hour HH:MM:SS, while the date format is YY-MM-DD-dd.

 

This RTC is suitable for applications such as remote systems, battery-backed systems, telecom switches, office equipment, and consumer electronics. The operating temperature range is 0°C to 70°C.
