1 GENERAL DESCRIPTION
1.1 INTRODUCTION
The ST6253B, ST6260B and ST6263B are mask
programmed
ROM
versions
of
ST62T53B,
ST6260B and ST62T63B 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 1. Programming wave form
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.
