ST6225L Datasheet | STMicroelectronics

DESCRIPTION 1.1 INTRODUCTION The ST6215L/25L are low voltage mask programmed ROM version of ST62T15C,T25C 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. 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 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. Figure 2.
