Rummaging through my junkspare parts box, I found this tiny 6-pin chip in a carrier. Curious, I looked it up and here's the first page of the datasheet.

It is an oscillator and 2^16 divider, from 32768 Hz to ½ Hz, intended to be used in quartz timebase watches with mechanical hands which explains the tiny package and leads. The date code indicates it was produced the 50th week of 1976. An interesting aspect is it runs on 1.5V from a silver oxide cell and at no more than 3.0V.

Oh well, not much use for this almost 50 year old chip except to write a blog page about it. 😉
