Original question:

TMS320LF2407A: TMS320LF2407

TMS320LF2407A: New life for the TMS320LF2407A?

Robert Cochran

Part Number: TMS320LF2407A


Hello TI,

I was surprised to see that the TMS320LF2407A is now back in stock on ti.com.  I had thought it was obsolete.  

Note that we are involved in supporting existing embedded systems that use these devices. 

Please provide an update on how long this part will be continued to be manufactured and sold by ti.com and your distributors (e.g., Mouser).

Also, please let us know if there will be any additional refreshes on the tools (SW and HW) to help your customers support products that use these devices. 

As others have also documented on your forum, we have had difficulty creating a stable CCS 3.3 tools environment with a working JTAG debugger.   We have one XDS510PP, and it seems that many hoops must be jumped through in order to use a USB-based JTAG debugger.   Also, it's not clear whether we must maintain a Windows XT PC, or whether a Windows 10 PC can host a stable tools environment that supports HW debugging and FLASH programming. 

Thank you

    There is minimal support for these devices at this point in time, please see the [FAQ] TMS320F240/TMS320F241/TMS320F243, LF240xA/LC240xA.

    I will confirm with another expert on this.

    The device was indeed in "Not Recommended for New Designs (NRND)" status for a while, but it was never in "End-of Life (EOL)" status. Meaning, the device is still in production.

    As of this moment, there are no plans to stop producing this device. However, this is primarily to support existing designs, not new designs.

    No. There will be no updates to the tool chain, either H/W or S/W.

    Understand. CCSv3.3 was designed under/for Win XP environment.

    Spectrum Digital, the company that made/sold XDS510, XS510PP+ & XDS510USB JTAG debug probes went out of business a few years ago, although some of these probes are still available online from sites such as eBay. However, Blackhawk may carry some emulators that you could get to work. Note that Eclipse-based CCS (v4.x and later) will not work with LF240xA devices. Ditto for XDS100/110/200 JTAG debug probes.

    If you are able to maintain a working Win XP machine, you are less likely to encounter issues. See below article on “hacks” to get CCS 3.3 working with on Windows 10:

    Thank you for all the great information.  We have witnessed at least one device evidently lose its FLASH programming (0's go back to 1's on some opcode bits).   Should we consider this device failed, or can we re-program it & expect another 20 years?   Also, please let me know if I should create a new support post for this issue or if we can take this off line since it's sensitive?

    That is a hard question to answer without analyzing the device. Sometimes, reprogramming a device brings it back to life. This is not the case if the bit-cell in the Flash memory has developed some issue. Unfortunately, we don't have the ability anymore to perform extensive failure analysis on this device. If it is feasible/practical, I would recommend replacing the failed device with a new one. 

    Any sensitive information can be shared directly via a private message.
