IMPORTANT: This is a 256-Mbit Flash Memory with an additional Security Sector (OTP). This sector is mapped from 1000000h to 1000007Fh (Data Pattern locations: 2000000h – 20000FFh). This sector can be purchased programmed and locked from the factory. If this is the case this sector needs to be excluded from programming and verification ranges as this data could have a unique number. The password protection sector is mapped to 1000080-1000083 (Data Pattern locations: 2000100h – 2000107h). The password protection lock bit can be used to lock the protection bits. Once locked our algorithm does not support unlocking of the bits. The configuration option for the factory lock is used to indicate the status of the chip. If this option is different than the state of the chip during verification or compare it will cause an error. If the part has not been locked by the factory the user can treat this sector as an additional memory sector with OTP sector protection. The Solid Sector Protection OTP bit is automatically set by the factory. Once the SPB is set it cannot be cleared but additional sectors may be locked.
