Submit the application program in one EPROM large enough to contain the entire memory map. If
the memory map has two user ROM areas with the same addresses, write the two areas on
separate EPROMs. Label the EPROMs with the addresses they contain.
Pack EPROMs securely in a conductive IC carrier for shipment. Do not use Styrofoam.
10.3 ROM Program Verification
The primary use for the on-chip ROM is to hold the customer’s application program. The customer
develops and debugs the application program, and then submits the MCU order along with the
application program.
Motorola 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. Motorola 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, Motorola will program the listing verify file into
customer-supplied blank EPROMs or preformatted Macintosh or DOS disks. All original pattern
media is filed for contractual purposes and is not returned.
Check the listing verify file thoroughly, then complete and sign the listing verify form and return the
listing verify form to Motorola. The signed listing verify form constitutes the contractual agreement
for the creation of the custom mask.
10.4 ROM Verification Units
After receiving the signed listing verify form, Motorola 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. Motorola then
produces ten MCUs, called ROM verification units (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 ten RVUs are free of charge with the minimum order quantity but are not production parts.
RVUs are not guaranteed by Motorola Quality Assurance.
