grammed ROM version of ST62T15C,T25C OTP

devices.

They offer the same functionality as OTP devices,

1.2 ROM READOUT PROTECTION

If the ROM READOUT PROTECTION option is

selected, a protection fuse can be blown to pre-

vent any access to the program memory content.

In case the user wants to blow this fuse, high volt-

age must be applied on the TEST pin.
