92 / 94 page ![]() ST52T400/T440/E440/T441 92/94 ORDERING INFORMATION Each device is available for production in user programmable version (OTP) as well as in factory programmed version (FASTROM). OTP devices are shipped to customers with a default blank con- tent FFh, while FASTROM factory programmed parts contain the code sent by the customer. There is one common EPROM version for debug- ging and prototyping which features the maximum memory size and peripherals of the family. Care must be taken to only use resources available on the target device.In order to obtain a list of part numbers see ST52T400/T440/E440/T441 Sales Type List at the beginning of the datasheet.
