Maxim Integrated DS1685E-3/TR Real-Time Clock

The Maxim Integrated DS1685E-3/TR is a robust real-time clock (RTC) and microprocessor supervisory component that provides a full binary-coded decimal (BCD) clock/calendar, 114 bytes of NV SRAM, and integrated microprocessor monitoring capabilities. Designed with precision and reliability in mind, this device is particularly suitable for a wide range of applications in computing, embedded systems, industrial controls, and telecommunications.

Key Features:

• Full BCD Clock/Calendar: The DS1685E-3/TR maintains seconds, minutes, hours, day, date, month, and year information with leap year compensation up to the year 2100. This ensures accurate timekeeping and date management for long-term deployment.
• 114 Bytes of NV SRAM: Nonvolatile SRAM provides storage for critical data that must be preserved during power loss, without the need for an external battery.
• Microprocessor Supervisory Functions: Includes power-fail warning, watchdog timer, and a programmable reset input/output to ensure system stability and reliability.
• Extended Temperature Range: The device operates over an industrial temperature range, making it suitable for harsh environments.
• Surface-Mount Package: The DS1685E-3/TR comes in a surface-mount package, allowing for efficient assembly and integration into modern PCB designs.
• Automatic Power-Fail Chip De-Select and Write-Protection: These features protect the integrity of the data stored in the RTC and NV SRAM during power loss or low voltage conditions.

Applications:

• Embedded Systems
• Industrial Control Systems
• Network Infrastructure
• Computing Systems
• Telecommunication Equipment
