RESET
Hardware Reset
The MBM29LV400TC/BC devices may be reset by driving the RESET pin to V
IL
. The RESET pin has a pulse
requirement and has to be kept low (V
IL
) for at least 500 ns in order to properly reset the internal state machine.
Any operation in the process of being executed will be terminated and the internal state machine will be reset
to the read mode 20
μ
s after the RESET pin is driven low. Furthermore, once the RESET pin goes high, the
devices require an additional t
RH
before it will allow read access. When the RESET pin is low, the devices will
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.
