MC68HC05B6_13 Datasheet, PDF (150/302 Pages) Freescale Semiconductor, Inc – Microcontrollers

13.1
EPROMS
For the MC68HC05B6, an 8 kbyte EPROM programmed with the customer’s 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.

Verification media
All original pattern media (EPROMs) are filed for contractual purposes and are not returned. A
computer listing of the ROM code will be generated and returned with a listing verification form.
The listing should be thoroughly checked and the verification form completed, signed and returned
to Freescale. The signed verification form constitutes the contractual agreement for creation of the
custom mask. If desired, Freescale will program blank EPROMs (supplied by the customer) from
the data file used to create the custom mask, to aid in the verification process.
13.3
ROM verification units (RVU)
13
Ten MCUs containing the customer’s ROM pattern will be provided for program verification. These
units will have been made using the custom mask but are for ROM verification 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 Freescale Quality Assurance.
