MAXIM INTEGRATED / ANALOG DEVICES DS1344D33TR Low-Current RTC
The DS1344D-33+T&R is a low-current, SPI and 3-wire real-time clock (RTC) in a 14-pin TDFN package. It offers precise timekeeping with seconds, minutes, hours, day, date, month, and year, automatically adjusting for leap years and months with fewer than 31 days. The device supports both 24-hour and 12-hour formats with an AM/PM indicator. It is designed for low power consumption with a standby current of around 350nA and can operate from a 3V to 5.5V power supply, functioning reliably with high-ESR crystals and supporting crystal ESR up to 100kΩ. The RTC includes two programmable alarms that can generate interrupts based on various time and date conditions, with support for don’t-care states for flexible alarm configurations. It features a 96-byte battery-backed NV RAM for data storage, burst mode for efficient address access, and is UL recognized. Operating over a temperature range of -40°C to 85°C, it supports Motorola SPI modes 1 and 3, as well as a standard 3-wire interface. The device is suitable for clock and timing applications in portable devices and medical equipment.
