Note

IMPORTANT: Microcontroller with Flash Memory.Default buffer value must be set to 255(FFh). The EncryptBuf is used on read back.If the Encryption array has been programmed EncryptBuf must contain the correct encryption keyto read the device properly. If encryption is not being used on this device all 64 bytes in theEncryptBuf must be set to 255(FFh). You must select the appropriate security mode to operate theSecure command.!!!Note: If both Encryption and Secure functions are required they must be done together byenabling both the Encrypt after programming’ and ‘Secure after programming’ options. ‘

BPM does not sell programmable devices, nor do we program devices directly. BPM makes programmers and accessories to make programming in-house fast, easy, and profitable.
