I2C clock chip: PCF8583P - Electronic Circuits Projects Diagrams Free

kcn · 14th March 2005, 05:36 AM

In Nigel's tutorials, he has an I2C clock board:

which uses the PCF8583P ("a real time, battery backed, CMOS I2C
clock chip in an 8 pin package").

Does anybody know of a Microchip part that does the same thing?

Is there a part (from Microchip or any other manufacturer) that is
similar, but requires even less external components?

Thank you.

Various manufacturers make RTC's (Real Time Clocks), Dallas Semiconductor make some popular ones - have a look at DS1302 and DS1307.

But I wouldn't expect them to use much less in the way of external components, the PCF8583P already uses hardly any?.
