Freescale inputs the customer’s application program code into a computer program
that generates a listing verify file. The listing verify file represents the memory map
of the MCU. The listing verify file contains the user ROM code and may also
contain non-user ROM code, such as self-check code. Freescale sends the
customer a computer printout of the listing verify file along with a listing verify form.
To aid the customer in checking the listing verify file, Freescale will program the
listing verify file into customer-supplied blank preformatted Macintosh or DOS
disks. All original pattern media are filed for contractual purposes and are not
returned.
Check the listing verify file thoroughly, then complete and sign the listing verify form
and return the listing verify form to Freescale. The signed listing verify form
constitutes the contractual agreement for the creation of the custom mask.
16.5 ROM Verification Units (RVUs)
After receiving the signed listing verify form, Freescale manufactures a custom
photographic mask. The mask contains the customer’s application program and is
used to process silicon wafers. The application program cannot be changed after
the manufacture of the mask begins. Freescale then produces 10 MCUs, called
RVUs, and sends the RVUs to the customer. RVUs are usually packaged in
unmarked ceramic and tested to 5 Vdc at room temperature. RVUs are not tested
to environmental extremes because their sole purpose is to demonstrate that the
customer’s user ROM pattern was properly implemented. The 10 RVUs are free of
charge with the minimum order quantity. These units are not to be used for
qualification or production. RVUs are not guaranteed by Freescale Quality
Assurance.
