Fast Program commands
The M29DW128F offers a set of Fast Program commands to improve the programming
throughput:
●
Write to Buffer and Program
●
Double and Quadruple Word, Program
●
Double, Quadruple and Octuple Byte Program
●
Unlock Bypass.
See either Table 14, or Table 13, depending on the configuration that is being used, for a
summary of the Fast Program commands.
When VPPH is applied to the VPP/Write Protect pin the memory automatically enters the Fast
Program mode. The user can then choose to issue any of the Fast Program commands. Care
must be taken because applying a VPPH to the VPP/WP pin will temporarily unprotect any
protected block.
Only one bank can be programmed at any one time. The other bank must be in Read mode or
Erase Suspend.
