Macronix International 

MX29F400C T/B

POWER-UP SEQUENCE

The MX29F400C T/B powers up in the Read only mode.

In addition, the memory contents may only be altered

after successful completion of the predefined command

sequences.

SECTOR PROTECTION WITHOUT 12V SYS-

TEM

The MX29F400C T/B also feature a hardware sector

protection method in a system without 12V power supply.

The programming equipment do not need to supply 12

volts to protect sectors. The details are shown in sector

protect algorithm and waveform.

CHIP UNPROTECT WITHOUT 12V SYSTEM

The MX29F400C T/B also feature a hardware chip

unprotection method in a system without 12V power

supply. The programming equipment do not need to

supply 12 volts to unprotect all sectors. The details are

shown in chip unprotect algorithm and waveform.
