Maximum 8349 processor frequency for temperature range -40°C ... +105°C

Quote from:

"MPC8349EA PowerQUICC II Pro Integrated Host Processor Hardware Specifications, Rev. 13"

"For temperature range = C, processor frequency is limited to

with a platform frequency of 266 and up to 533 with a platform

frequency of 333"

It seems that there is a type in the statement above. Which is the maximum processor frequency for the temperature range "C" (i.e. -40...+105)?

With a platform frequency of 333Mhz it is clear to be 533Mhz, but with a platform frequency of 266?

Have a great day,

Actually for all 834x family (MPC8343, MPC8347 and MPC8349) this note says

For temperature range = C, processor frequency is limited to 400 (PBGA) with a platform frequency of 266 and up to 533 (TBGA) with a platform frequency of 333

Because MPC8349 is TBGA only they change it in way you have read in the MPC8349 hardware specs. For the MPC8343 they correspondingly change it to

“For temperature range = C, processor frequency is limited to 400 with a platform frequency of 266 and up to with a platform frequency of 333”

Thanks for the answer.

Do you know if there is a version of the 8349 (or a compatible processor) that works at higher frequency in the extended temperature range?
