Typ1

1 Typical program and erase times assume nominal supply values and operation at 25 °C. All times are subject to

change pending device characterization.

Initial

max2

2 Initial factory condition: < 100 program/erase cycles, 25 °C, typical supply voltage.

Max3

3 The maximum program and erase times occur after the specified number of program/erase cycles. These maximum

values are characterized but not guaranteed.

Tdwprogram CC C Double word (64 bits) program time

4 Actual hardware programming times. This does not include software overhead.

2 Ambient temperature averaged over duration of application, not to exceed recommended product operating

temperature range.

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.
