Other Parts Discussed in Thread: 66AK2H12

Hello,

I would like to know about bus width of 66AK2H12/06 teranet.
There is no description about teranet bus width in 66AK2H12/06 datasheet.

Instead, it describes about TeraNet in sprabk5a:
http://www.ti.com/lit/an/sprabk5a/sprabk5a.pdf

My question:
- Since all TeraNets in 66AK2H12/06 operate as CPU/3 frequency, it is all 128bit bus width. right?

- TeraNet which operate as CPU/2 frequency have 256bit bus width. right? (like C6678.)

Best regards, RY

TeraNet 3_B and 3_C are 256b CPU/3

The rest (TeraNet 3_A, 3_M-3_T) are 128b CPU/3

Chad

Chad-san,

Thank you for your answer.
Could you let me know about C665x? (one of my important customer needs it.)

- TeraNet 3_A (CPU/3) ..

- TeraNet3P_A (CPU/3) ..

- TeraNet 3P_B (CPU/3) ..

- TeraNet 3P_Tracer (CPU/3) ..

- TeraNet 6P_B (CPU/6) ..

Best regards, RY

For C665x, the 3_A is 128b CPU/3 all the 3P's are 32bit CPU/3 and 6P's are 32bit CPU/6.

The #P_*** TeraNet's are for connections to the config buses or slow IP and are 32bit across the Keystone Platforms.

Best Regards,

Chad
