TMS320F28379D and TMS320F28377D

Dear all,

I read that 379D and 377D are exactly the same if CLB is not used.

Just to make sure, do this mean that I can assemble on my designed board one device or the other using the same hardware and same software and i will not see any difference (CLB never used)?

Best regards and thank you,

NUBA

    Nuba,

    Mostly true. An exception will be the PARTIDH register, which is a read-only register with a value indicating the device (see datasheet). This will be different between F28377D and F28379D. If your software reads this register for some reason, you will need to make accommodation for this difference. Also, the flash API algorithms (used to do in-field flash upgrades) read this register to make sure the device is what it is supposed to be. You would not be able to build your code with the APIs resident in memory. They would need to be streamed in at re-programming time. If you aren't doing flash upgrade stuff, no need to worry about this.
