C2000 micro controller memory

Jingzhe Wu

Hi everyone,

I am currently programing with a F28027 C2000 Piccolo Launchpad and if I am correct the device is a 32 bit controller. However as can be seen from the memory blocks from F28027 Linker Command File, the memory origin and length are, for example, origin = 0x3F6000, length = 0x001F80.

I wonder why there are just 6 hex digits after 0x? I think normally a 32 bit device will have 8 hex digits to represent 32 binary digits.

I am not sure if I understand correctly. Could anyone help?

Thank you.

Hi,

The memory length varies wrt devices and their memory capacity.

Hi Jingzhe!

0x3F6000 = 0x003F6000, 0x001F80=0x00001F80

There is no reason to write extra zeros if the range of addresses available is less than 0xFFFFFF.

Igor

Looks like this has been resolved - as a side note, the C28x program address bus is 22-bits. Data bus is 32-bits.
