ST92195B - GENERAL INFORMATION

3.2 ORDERING INFORMATION

Each device is available for production in a user

programmable version (OTP) as well as in factory

coded version (ROM). OTP devices are shipped to

customer with a default blank content FFh, while

ROM factory coded parts contain the code sent by

customer. The common EPROM versions for de-

bugging and prototyping features the maximum

memory size and peripherals of the family. Care

must be taken to only use resources available on

the target device.

3.2.1 Transfer Of Customer Code

Customer code is made up of the ROM contents

and the list of the selected options (if any). The

ROM contents are to be sent on diskette, or by

electronic means, with the hexadecimal file gener-

ated by the development tool. All unused bytes

must be set to FFh.
