I'm trying to identify a small 0.4 mm x 0.4 mm 6-pin DIP IC chip that
has two rows of part numbers written on it. 493, 328T, and a symbol
"o----" (round dot with a solid line above it, like a musical note
rotated 90 degrees
. Anyway its package has a ceramic base with
silver/steel cap and a gold outline. The board has an antenna and a PIC
processor, but the part doesnt seem to be directly connected to either
of these components based on probing. I did notice 1.5 V input on pin 2
(I think). It's a low power component, and the whole board fits in the
palm of your hand. Some have suggested a crystal filter, but I can't
find any data sheet that reflects the numbers written on this IC. I've
tried googling, but the results weren't useful. Any ideas what it is,
or where I ought to look?
Thanks,
Herb
