Hi,

as usual, Philips specification is rather conservative. Under very
simple lab conditions in an automated test we did not see any failures
within 500,000 cycles. This was just done as a sanity check. So under
"normal" conditions, which is that not all reprogramming cycles will
happen at maximum temperature, the number of reprogramming cycles will
be 1 or 2 orders of magnitude higher than the specified 10,000 cycles.
I guess this is where the difference between the marketing statement
"our device can do 1 Mio cycles" and the worst case specification "we
guarantee (under worst case conditions) 10k cycles" comes into the game.
