Real Time Clocks ICs

DS1306E+ Description

The DS1306E+ from Analog Devices Inc./Maxim Integrated is a highly reliable SPI-interfaced real-time clock/calendar (RTC) IC designed for precision timekeeping in embedded systems. Operating within a 2V to 5.5V supply range, it features a low power consumption of 25.3µA to 81µA, making it ideal for battery-backed applications. The device includes 96 bytes of NV SRAM for data storage and supports both 12-hour and 24-hour time formats with seconds, minutes, hours, day, date, month, and year tracking. Packaged in a 20-pin TSSOP and rated for 0°C to 70°C, it is RoHS3 compliant and suited for surface-mount assembly.

DS1306E+ Features

• Low Power Consumption: As low as 25.3µA for extended battery life.
• Wide Voltage Range: Operates from 2V to 5.5V, compatible with various power sources.
• SPI Interface: Ensures fast and reliable communication with microcontrollers.
• Integrated Memory: 96B of SRAM for auxiliary data storage.
