(1) The difference between revision A silicon and revision B silicon is the addition of the InstaSPIN™ code in revision B silicon. The InstaSPIN code in secure ROM is execute-only with no read access. For more details, see the TMS320F28026F, TMS320F28027F InstaSPIN™-FOC Software Technical Reference Manual. In revision B silicon, the original ROM contents from revision A silicon have not been modified. All new additions for revision B silicon have been placed in the unused locations of ROM in revision A silicon. However, the ROM revision code has been updated on revision B and the ROM checksum will be different between the two revisions.
