    Dallas Key Security Chip

    Dallas Key DS1991l-f5 chip used for security on megatouch - touch screen video machines. It is a multikey-I button 1152bit secure read-rite none volotile memory. Memory cannot be deciphered without a match 64bit password memory is par***ioned into 3 blocks of 384 bits each. 64 bit password & id fields for each block.

    Can anyone tell me where i can find a reader to read the chip and a programmer and software to programme the chip also how to crack the password.

    Any help gratefully appreciated

    Sample applications are probably available from Dallas Semiconductor for HW/SW.

    I woundn't think brute forcing a 64 bit key is viable.
