PCA2117DUGS/DAZ

Display Drivers Overview

The PCA2117DUGS/DAZ is a real-time clock (RTC) and watchdog timer integrated circuit designed for low-power applications. It features an I²C-bus interface for communication with host processors. The device includes a dedicated interrupt output pin to signal time base or watchdog events. It operates with a wide supply voltage range and maintains timekeeping via a backup battery input, ensuring continuous operation during main power loss. The component is housed in a small package suitable for space-constrained designs.

Display Drivers Feature Summary

• Integrated real-time clock functionality with calendar and alarm capabilities
• Built-in watchdog timer for system reliability monitoring
• I²C-bus interface for simple host connectivity
• Low-power operation with backup battery support

Display Drivers Applications

• Portable consumer electronics requiring accurate timekeeping
• Industrial control systems needing watchdog supervision
• Battery-powered devices with intermittent main power supply

Display Drivers Procurement Notes

Verify the specific suffix DAZ against the manufacturer's current ordering guide to confirm package type and tape/reel specifications. Ensure compatibility with the target I²C bus voltage levels and check for any regional compliance certifications required for the final assembly location. Cross-reference the full orderable part number with official distributors to avoid substitution errors.

Display Drivers Selection Notes

Select this component when a combined RTC and watchdog solution is required to minimize board space and component count. It is suitable for designs where low standby current is critical and I²C connectivity is available. Consider the operating temperature range and package availability relative to the production volume requirements.

Display Drivers Part Context

This part belongs to NXP's line of real-time clock and watchdog timer ICs. These components are commonly used in embedded systems to provide precise time management and fault detection. The family typically offers various interface options and package sizes to accommodate different design constraints and performance needs.

Display Drivers Replacement Considerations

Check for direct pin-to-pin replacements within the same product family that may offer updated packaging or enhanced feature sets. Verify electrical parameter compatibility, particularly supply voltage ranges and I²C timing specifications, before substituting with similar RTC/WDT devices from other manufacturers.
