12.6.2 ROM Version
The ST6215C/25C are mask programmed ROM
version of ST62T15C,T25C OTP devices.
They offer the same functionality as OTP devices,
selecting as ROM options the options defined in
the programmable option byte of the OTP version.
Figure 81. Programming Circuit
Note: ZPD15 is used for overvoltage protection
ROM Readout Protection. If the ROM READOUT
PROTECTION option is selected, a protection
fuse can be blown to prevent any access to the
program memory content.
In case the user wants to blow this fuse, high volt-
age must be applied on the VPP pin.
