PT7C4302AWEX

Real Time Clock Overview

The PT7C4302AWEX is a Real-Time Clock (RTC) integrated circuit manufactured by Diodes Incorporated. It features a 3-wire serial interface for communication and includes 31 bits of internal memory for clock/calendar data storage. The device is housed in an 8-SOIC package with a width of 3.90mm. It supports battery backup switching to maintain timekeeping during power loss. The component operates within standard industrial temperature ranges and is designed for applications requiring precise time management.

Real Time Clock Feature Summary

• Integrates a real-time clock and calendar function with 31-bit internal memory capacity.
• Utilizes a 3-wire serial interface for simplified connection and data transfer.
• Includes battery backup switching capability to ensure continuous operation during main power failure.

Real Time Clock Applications

• Time management systems in electronic devices
• Data logging equipment requiring timestamping
• Embedded systems needing accurate calendar tracking

Real Time Clock Procurement Notes

Verify the specific suffix 'WEX' against the manufacturer's current datasheet to confirm availability status, as some variants may be scheduled for obsolescence. Ensure compatibility with the required 3-wire serial protocol and SO-8 package dimensions for PCB layout. Confirm RoHS compliance requirements if applicable to your manufacturing standards before finalizing procurement.

Real Time Clock Selection Notes

Select this component when a compact RTC solution with minimal pin count is required. The 3-wire interface reduces board space compared to I2C or SPI alternatives. Consider the 31-bit memory size for sufficient date/time storage needs. Verify that the 8-SOIC package fits within the designated footprint constraints of the target design.

Real Time Clock Part Context

This part belongs to Diodes Incorporated's Real-Time Clock product line, categorized under Clock & Timer ICs. It serves as a dedicated timing solution for embedded applications. The series provides reliable timekeeping functions with low power consumption characteristics typical of modern RTC designs from this manufacturer.

Real Time Clock Replacement Considerations

Check for direct substitutes within the same family or compatible RTCs with identical 3-wire interfaces and SO-8 packages. Verify pin-to-pin compatibility if replacing on existing boards. Note that some distributors indicate potential obsolescence for certain variants, so alternative sourcing strategies may be necessary.
