List of numbers of page write
The above numbers are maximum bytes for respective types.
Any bytes below these can be written.
In the case BR24L02-W, 1 page=8bytes, but the page write cycle write time is 5ms at maximum for 8byte bulk write.
It does not stand 5ms at maximum × 8byte=40ms(Max.).
*1 In BR24L16-W, A2 becomes P2.
*2 In BR24L08-W, BR24L16-W, A1 becomes P1.
*3 In BR24L04-W, A0 becomes PS, and in BR24L08-W and in BR24L16-W, A0 becomes P0.
