Can anyone help with Atmel ATmega169
rev numbers, I have two chips marked code
0339 and another 0352, is thisjust
week 39 and week 52 of 2003? How
can I tell what REV number are they?
They both behave different so they are
either REV B & REV C or REV C & REV D.
Anyone help?

Phil

Yes,


You need to look under the device, and for Atmel IC's
and Rev ID is normally the last letter of one
of the lines.

Thanks, but still none the wiser as reverse markings are:
week 52 chip: 3H0106   35579D 1-A 3H0345
week 39 chip: 3G0822A 35579D 1-A 3G0339

The week 52 device takes an extra 100uA with
the LCD which is what the REV C device should do.

According to the datasheet, the top 4 bits of the device identification
register (accessible via jtag only), 0 = REVA ... 3 = REVD
