The DS1340U-33+T&R from Maxim Integrated is a highly precise, full-featured real-time clock (RTC) module, designed to provide timekeeping functionality in a wide range of applications. This RTC module is especially suitable for systems that require high accuracy and reliability over time, including industrial control systems, data loggers, medical devices, and telecommunication infrastructure.

Key Features

• Accuracy: The DS1340U-33+T&R maintains exceptional time accuracy with minimal drift, ensuring that time-dependent applications function correctly over long periods.
• Battery Backup: It includes a battery backup input that allows the clock to continue keeping time even during power failures, making it ideal for critical systems that cannot afford to lose time tracking.
• Trickle-Charge Capability: The device supports trickle-charge capability, which can be used to recharge a backup battery during normal operation, thereby extending the backup battery's life.
• Serial Interface: The module uses an I²C serial interface for communication, which facilitates easy integration with most microcontrollers and allows for simple design-in with minimal I/O lines required.
• Low Power Consumption: It is designed for low power consumption, making it a perfect choice for battery-powered devices.
• Extended Temperature Range: The DS1340U-33+T&R operates over an industrial temperature range, ensuring reliable performance in harsh environments.

Package and Supply

The device comes in a compact, surface-mountable µSOP-8 package, which is suitable for space-constrained applications. Its supply voltage is specified at +3.3V, aligning with common system power rails in modern electronic designs. The "+T&R" designation indicates that this product is provided in tape and reel packaging, which is optimized for automated pick-and-place assembly processes, making it a convenient choice for mass production.
