MBM29DL16XTE/BE70/90
• Accelerated Program Operation
MBM29DL16XTE/BE offer accelerated program operation which enables the programming in high speed. If the
system asserts VACC to the WP/ACC pin, the device automatically enters the acceleration mode and the time
required for program operation will reduce to about 60%. This function is primarily intended to allow high speed
program, so caution is needed as the sector group will temporarily be unprotected.
The system would use a fact program command sequence when programming during acceleration mode.
Set command to fast mode and reset command from fast mode are not necessary. When the device enters the
acceleration mode, the device automatically set to fast mode. Therefore, the pressent sequence could be
used for programming and detection of completion during acceleration mode.
Removing VACC from the WP/ACC pin returns the device to normal operation. Do not remove VACC from WP/
ACC pin while programming. See “(18) Accelerated Program Timing Diagram” in ■TIMING DIAGRAM.
Erase operation at Acceleration mode is strictly prohibited.
