Real-Time Clock products offer a diverse range of real-time clock (RTC) solutions for networking and embedded applications. The primary function of RTC is to keep time and calendar data.
Not all obsolete parts will have a direct replacement. However, we recommended that you contact your regional sales office.
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.
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.
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.
