1 GENERAL DESCRIPTION
1.1 INTRODUCTION
The ST6208L/09L/10L/20L are low voltage mask
programmed ROM version of ST62T08C/T09C/
T10C/T20C 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,
with the exception of the LVD Reset that is not
available.

1.2 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 voltage must be applied on the TEST pin.
