Power and Reset Specification
Power-Up and Power-Down
Upon power-up the flash memory interface is defined by the SERIAL pin being at Vss
(parallel) or Vcc (serial).
After the interface is defined it can not be changed until a full power-down is completed
and a power-up sequence is reinitiated.
Power supply sequencing is not required if VPP is connected to VCC or VCCQ. Otherwise
V
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.

• During power-up if the SERIAL pin is at Vss the flash memory will be a x16 parallel
• During power-up if the SERIAL pin is at Vcc the flash memory will be a SPI
