CRT97C11LJP

Video Processing Overview

The CRT97C11LJP is a high-performance, low-power CMOS Real-Time Clock (RTC) and battery-backed static RAM device manufactured by SMSC. It provides precise timekeeping with seconds, minutes, hours, day, date, month, and year information, including leap-year compensation valid through the year 2100. The device features an integrated crystal oscillator and connects to a microprocessor via a standard two-wire serial interface. It includes 114 bytes of battery-backed static RAM for data storage during power failures.

Video Processing Feature Summary

• Provides accurate real-time clock functions with automatic leap-year compensation
• Integrates a crystal oscillator requiring minimal external components
• Features a simple two-wire serial interface for easy microprocessor connection
• Includes battery-backed static RAM for secure data retention

Video Processing Applications

• Portable computers and laptops requiring system timekeeping
• Industrial control systems needing reliable timestamping
• Consumer electronics with battery backup requirements
• Telecommunications equipment for network synchronization

Video Processing Procurement Notes

Verify the specific suffix 'LJP' against official SMSC documentation to confirm package type and temperature range. Ensure compatibility with your system's voltage levels and serial interface protocols before procurement. Cross-reference part numbers with current manufacturer listings to avoid obsolete stock.

Video Processing Selection Notes

Select this component when a compact RTC solution with integrated memory is required. Consider its low power consumption and small form factor for space-constrained designs. Evaluate the need for its specific RAM capacity and interface simplicity compared to discrete solutions or more complex RTC chips.

Video Processing Part Context

SMSC was a leading developer of smart mixed-signal connectivity solutions before being acquired by Microchip Technology in 2012. This part belongs to the legacy SMSC product line, which focused on connectivity and timing devices. Post-acquisition, support and availability are managed under Microchip's portfolio.

Video Processing Replacement Considerations

Check Microchip's official documentation for direct replacements or pin-compatible alternatives within their RTC family. Verify electrical specifications and interface compatibility if substituting with other manufacturers' RTCs.
