TMS320F28027F: Difference between LAUNCHXL-F28027F and LAUNCHXL-F28027

Part Number: TMS320F28027F
Other Parts Discussed in Thread: TMS320F28027, LAUNCHXL-F28027, CONTROLSUITE

Hello, 

This may be a straightforward question, but I was wondering what the difference between TMS320F28027F and TMS320F28027 ?

I have flash locked my device and I would like to replace the IC on the Launchpad. I understand that buying the LAUNCHXL-F28027F will be easier but I have already proceeded to solder the pin outs to other connections and it has been locked to place. So, changing out the whole controller is not an option. 

I was not able to find the hardware package for the LAUNCHXL-F28027F with the bill of materials to know which MCU is installed on it. I was able to find the hardware package of LAUNCHXL-F28027, which pointed that TMS320F28027PTS is installed on it. 

I checked under the microscope and saw that LAUNCHXL-F28027F has TMS320F28027PTT installed. 

My question remains now is that the only difference between the two is that:

1. TMS320F28027PTT - Has INSTAspin

    TMS320F28027PTS - Does not have INSTAspin

is this information correct?

2. Where can i find the hardware package for LAUNCHXL-F28027F ?

  • The F28027 and F28027F are the same device, pin-to-pin compatible, the only difference being the ROM. The device with the 'F' suffix has InstaSPIN-FOC loaded in secure memory. The HW package can be found in ControlSUITE - it is the same for the non-'F' designated Launchpad

  • I just checked a F28027F Launchpad I had on hand - the silk screen on the actual MCU did say F28027FPTT, so I believe you'll need the 'F' to be shown on the package to have a version with InstaSPIN in the secure memory
