13.1
EPROMS
For the MC68HC05B6, an 8 kbyte EPROM programmed with the customerâs software (positive
logic for address and data) should be submitted for pattern generation. All unused bytes should be
programmed to $00. The size of EPROM which should be used for all other family members is
listed in Table 13-2.
The EPROM should be clearly labelled, placed in a conductive IC carrier and securely packed.

Veriï¬cation media
All original pattern media (EPROMs) are ï¬led for contractual purposes and are not returned. A
computer listing of the ROM code will be generated and returned with a listing veriï¬cation form.
The listing should be thoroughly checked and the veriï¬cation form completed, signed and returned
to Motorola. The signed veriï¬cation form constitutes the contractual agreement for creation of the
custom mask. If desired, Motorola will program blank EPROMs (supplied by the customer) from
the data ï¬le used to create the custom mask, to aid in the veriï¬cation process.
13.3
ROM veriï¬cation units (RVU)
13
Ten MCUs containing the customerâs ROM pattern will be provided for program veriï¬cation. These
units will have been made using the custom mask but are for ROM veriï¬cation only. For
expediency, they are usually unmarked and are tested only at room temperature (25°C) and at
5 Volts. These RVUs are included in the mask charge and are not production parts. They are
neither backed nor guaranteed by Motorola Quality Assurance.
