Hi Isa,
if you use HCT ICs (e.g. 74HCT541) you can power it with 5V and drive it
with an input signal range 0-3.3V(they have a 2V of treshold high level

It's simple to show that
A * (B % C) can overflow!
For example if :
A = 214751
B = 10000
C = 30000
214751 * 30000 = 0x1800134d0
Is it right... Rif: DSP56807 bootloader / S-Record number of lines

Ok, I found another that using DS2432!
Which is code size to decode DS2432 information ?
P.S. DS2432 seems expensive (for my applicaton) (around 3.9 euro).
