1 GENERAL DESCRIPTION

1.1 INTRODUCTION

The ST6253C, ST6260B and ST6263B are mask

programmed

ROM

versions

ST62T53C,

ST6260B and ST62T63C 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,

except the LVD & OSG options that are not availa-

ble on the ST6260B/63B ROM device.

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.
