how many address lines ?
I got one doubt regarding bus interface .
A peripheral of 512 Mbits has 16 bit data bus width.
I need to calculate the total number of address lines of the peripheral.
If it is 512 Mbyte and 16 bit databus width then ,as per my understanding the total number of address lines required will be 25 lines
512 Mbytes = (2^20) x 2^ 9 = 2^ 29
The data bus is 16 bits so Address bus will be ( 2^29) / (2x2^3) = 2 ^ 25
So total of 25 lines ..
But if the capacity is 512 Mbits ,I got confused on how many number of address lines will be required ?
Could anyone please help me to get it clarified?
Many Thanks
