APPLICATION NOTE
ST7 CUSTOMER ROM CODE RELEASE INFORMATION
by MCD Applications
INTRODUCTION
When their ST7 ROM code is ready to be mask programmed, customers send their execut-
able file to ST in Motorola .s19 format. When ST receives it, this file is reformatted by a propri-
etary automation tool called NEWGET in order to generate the mask levels and test patterns
for manufacturing and testing the devices.
Consequently, when customers receive back their ROM code for validation before ST pro-
grams their parts, they receive a file in a different format from the one they sent originally. To
help customers understand why the file is different, this Application Note lists the modifications
that occur when the file is processed by NEWGET.
