Replacement part for TMS320C54CST

Other Parts Discussed in Thread: TMS320VC5407

We had used TMS320C54CST in one of our designs sometimes back. Since it's obsolete, could you please recommend a replacement part from 54x series? Would there be a pin-to-pin replacement? Since 54CST had a UART, replacement would preferably be one with UART as well.

PS: We have done some analysis and TMS320VC5407 seems to be a good match. Can somebody please verify?

    Hi Hyun

    Thanks for your kind response. Here are answers to your questions in the same order:

    1- 120 MHz or more

    2- We need one with extended addressing mode (as in 54CST). Following are main peripherals being used:

    - On-chip RAM (40K x 16)

    - 2x McBSP

    - UART

    3- No preference

    4- Preferably less than 54CST

    A drop-in replacement would be preferred.

    Best Regards

    Ahmad
