Maxim Integrated DS1340C-33#T&R Real-Time Clock

The DS1340C-33#T&R from Maxim Integrated is a low-current, real-time clock (RTC) with a full binary-coded decimal (BCD) clock/calendar and 56 bytes of NV SRAM. This high-precision timekeeping device is particularly suitable for applications that require accurate timekeeping under varying environmental conditions. Its built-in power-sense circuitry detects power failures and automatically switches to the backup supply, ensuring seamless timekeeping functionality.

With an operating temperature range of -40°C to +85°C, the DS1340C-33#T&R is designed to perform reliably in a variety of settings, making it an ideal component for industrial systems, telecommunications, embedded electronics, and portable medical devices. The device operates on a supply voltage of 3.3V, making it compatible with contemporary digital systems.

The clock/calendar functionality of the DS1340C-33#T&R provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with an AM/PM indicator.

One of the key features of this RTC is its I²C interface, which facilitates simple integration into existing designs, allowing for easy communication with microcontrollers and other digital systems. The DS1340C-33#T&R also includes two programmable time-of-day alarms and a programmable square-wave output, offering additional functionality for complex time-related tasks.

The device's packaging is in a tape and reel format, denoted by the T&R suffix, which is suitable for automated assembly processes, making it convenient for mass production applications. The robust design and the long-term data retention of the NV SRAM make the DS1340C-33#T&R a reliable choice for critical applications where data integrity and timekeeping accuracy are paramount.

Overall, the Maxim Integrated DS1340C-33#T&R RTC is a versatile and reliable component that offers precision timekeeping, low power consumption, and additional memory features that are essential for modern electronic systems.
