Add To BomDS1339U-33 General Description
The DS1339U-33+ is a low-power real-time clock (RTC) with an I2C serial interface. It operates at a voltage range of 1.8V to 5.5V and has a timekeeping accuracy of ±2 minutes per month in the 0°C to +40°C temperature range. The clock/calendar function tracks seconds, minutes, hours, day, date, month, and year with automatic leap year compensation.The DS1339U-33+ has dual programmable alarms with a repeat mode that triggers at a specified time or day of the week. It also features a programmable square-wave output, a 16-byte SRAM for data storage, and a trickle charger to back up the lithium coin-cell battery.Other features of the DS1339U-33+ include a battery low flag, time stamp for power fail, and multiple address pins for up to eight devices on the same I2C bus. The device comes in a small 8-pin μSOP package, making it suitable for compact applications such as portable devices, medical equipment, and industrial automation
