Real Time Clock (RTC) FAQs

Is there a replacement for an obsolete part?

Not all obsolete parts will have a direct replacement. However, we recommended that you contact your regional sales office.

What are the benefits for RTC module to integrate crystal?

The benefits are PCBA footprint saving and shortened test process and design lead time. Also, it can speed up end-product mass production schedule, and also enhance clock accuracy and RTC consistency.

What is the 3-wire interface?

3-wire interface is the same as SPI with Data, CLK and CS signals to support high frequency clock without the need of pull-up resistors. Please refer to datasheetsfor detailed application.

What is the lead finish for Pericom products? What about lead-free?

All Pericom's products that are not lead-free are composed of 85% Sn and 15% Pb. For lead-free products, they are composed of 100% matte Sn. Lead-free products are marked and ordered with the letter "E" suffix at the end of the part number.

Where can I find Mean Time Before Failure (MTBF) or Failures In Time (FIT) values for Pericom products?

FIT and MTBF data can be found at Pericom's Quality webpage.

Where can I find the information on your Pb-free and "Green" packaging?

Lead (Pb)-Free and Green information can be found on individual datasheets or Pb-Free & Green Page.
