DESCRIPTION

The ST1200 is a 256 bit OTP (one time program-

mable) EPROM, organized as 256 x 1, manufac-

tured using ST’s highly reliable and well proven

NMOS technology.

The security mechanism, called Lock-Out, allows

the user to inhibit, in write mode, the access to a

memory section of 96 bits. Thus, by blowing a

polysilicon fuse, the address bits 0 to 95 can be

protected against write.

The 9th bit of the ST1200 is set to a logical “1” for

device identification purposes. In order to avoid

any modification, ST has mask-programmed this

bit to the logic “1” state.
