Hardware Reset
The MBM29LV400TC/BC devices may be reset by driving the RESET pin to V
requirement and has to be kept low (V
Any operation in the process of being executed will be terminated and the internal state machine will be reset
to the read mode 20 s after the RESET pin is driven low. Furthermore, once the RESET pin goes high, the
devices require an additional t
be in the standby mode for the duration of the pulse and all the data output pins will be tri-stated. If a hardware
reset occurs during a program or erase operation, the data at that particular location will be corrupted. Please
note that the RY/BY output signal should be ignored during the RESET pulse. See Figure 12 for the timing
diagram. Refer to Temporary Sector Unprotection for additional functionality.
If hardware reset occurs during Embedded Erase Algorithm, there is a possibility that the erasing sector(s)
cannot be used.
