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.
