ST1200 Overview
The ST1200 is a 256 bit OTP (one time programmable) EPROM, organized as 256 x 1, manufactured 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.
