Real Time Clocks (RTCs) provide time and/or date information in almost any electronic device which needs to keep accurate time. The clock types are binary counter, clock/calendar/supervisor, elapsed time counter, phantom time chip, portable system controller, temperature recorder, time event recorder, and timer clock peripheral.  They contain memory sizes ranging from 2 B to 2 MB and have interface options of I2C, Parallel, Serial, SPI, 1-Wire, 2-Wire, 3-Wire, and 4-Wire.

FAQ

Which parts are supplied in stock?

Zhongdeyuan (Hong Kong) Technology Co., Limited supplies integrated circuits (ICs), resistors, capacitors, inductors and diodes from stock. Open a part number to see the brand and specifications, then request a quote for quantity and lead time. Genuine stock is confirmed when you inquire.

How do I request a quote by part number?

Open the part page and check the brand, package and electrical specifications against your requirement, then send an inquiry with the part number, quantity and target lead time. For several lines, use BOM matching and list every part once.

Do you support BOM matching?

Yes. Send the part numbers, quantities and brands. We check integrated circuits, resistors, capacitors and inductors against current stock, then reply with the quantity that can be delivered and the lines that need to be ordered.
