Introduction
B.1 Introduction
ROM devices offer an attractive low cost alternative to flash devices. In a high-
volume application, flash devices may be used to develop, test, refine, and
finalize the application code. When the code has been finalized, the code can
be submitted to Texas Instruments for masking into the on-chip program ROM.
Figure B−1 illustrates the procedural flow for developing and ordering
TMS320 masked parts. When ordering, there is a one-time, nonrefundable
charge for mask tooling. A minimum production order per year is required for
any masked-ROM device. ROM codes will be deleted from the TI system one
year after the final delivery.
