Microchip MCP795W12-I/SL Real-Time Clock/Calendar

The MCP795W12-I/SL is a highly integrated Real-Time Clock/Calendar (RTCC) from Microchip Technology, designed for effective time tracking and data logging in embedded systems. This compact, surface-mount device provides a full-featured solution for timekeeping in electronic applications requiring accurate time and date information.

Key Features:

• Timekeeping: This RTCC offers hours, minutes, and seconds in 12/24-hour formats along with the day, date, month, and year data. Its leap year compensated to 2399, ensuring reliable date information for decades.
• Battery Backup: With a battery backup input for continuous timekeeping and low power operation, the MCP795W12-I/SL maintains accurate time even when the main power is lost.
• Memory: It includes 64 bytes of battery-backed SRAM and 1 Kbit of EEPROM, which provides convenient data storage for critical or frequently accessed data.
• Digital Trimming: The device allows digital trimming for precise timekeeping, which compensates for crystal tolerance and temperature.
• Communication Interface: It supports the industry-standard SPI serial interface for easy integration with most microcontrollers.
• Alarm Function: Programmable calendar and clock alarms ensure timely alerts for scheduled events.
• Power-Fail Timestamp: A time-stamp feature records the time when the device switches to battery backup, providing useful diagnostics in the event of a power failure.
• Extended Temperature Range: The MCP795W12-I/SL operates over an industrial temperature range, making it suitable for a wide variety of applications.

Applications:

The MCP795W12-I/SL is ideal for a diverse range of applications, including industrial control systems, utility meters, medical devices, home automation, and any embedded system that requires an accurate time base for operation or data logging purposes.

Package and Quality:

This RTCC comes in a compact 8-pin SOIC package, ensuring a minimal footprint on the PCB. It is also RoHS compliant and adheres to Microchip's commitment to high-quality standards.
