ECC circuitry provides correction of single bit faults and is used to improve further

automotive reliability results. Some units will experience single bit corrections throughout

the life of the product with no impact to product reliability.

Flash power supply DC characteristics

Table 31 shows the power supply DC characteristics on external supply.

Note:

Power supply for data flash is actually provided by code flash; this means that data flash

cannot work if code flash is not powered.
