g 1. Confirmation

Specify the name of the product being ordered and the type of EPROMs submitted.

Three EPROMs are required for each pattern.

If at least two of the three sets of EPROMs submitted contain identical data, we will produce masks based on this data. We

shall assume the responsibility for errors only if the mask ROM data on the products we produce differs from this data.

Thus, extreme care must be taken to verify the data in the submitted EPROMs.

Checksum code for entire EPROM

(hexadecimal notation)

(1) Set the data in the unused area (the shaded area of

the diagram) to “FF16”.

(2) The ASCII codes of the product name “M37478M8–”

must be entered in addresses 000016 to 000816. And

set the data “FF16” in addresses 000916 to 000F16.

The ASCII codes and addresses are listed to the right

in hexadecimal notation.
