Power and Reset Specifications
Power-Up and Power-Down
Power supply sequencing is not required if VPP is connected to VCC or VCCQ. Otherwise
VCC and VCCQ should attain their minimum operating voltage before applying VPP.
Power supply transitions should only occur when RST# is low. This protects the device
from accidental programming or erasure during power transitions.
Reset Specifications
Asserting RST# during a system reset is important with automated program/erase
devices because systems typically expect to read from flash memory when coming out
of reset. If a CPU reset occurs without a flash memory reset, proper CPU initialization
may not occur. This is because the flash memory may be providing status information,
instead of array data as expected. Connect RST# to the same active low reset signal
used for CPU initialization.
Also, because the device is disabled when RST# is asserted, it ignores its control inputs
during power-up/down. Invalid bus conditions are masked, providing a level of memory
protection.
