1. Typical data retention values are based on measured response accelerated at high temperature and derated to a
constant 25 °C use profile. Engineering Bulletin EB618 does not apply to this technology. Typical endurance defined in
Engineering Bulletin EB619.
2. Cycling endurance represents number of program/erase cycles at –40 °C ≤ T_j ≤ °C.
3.3.3 Flexbus switching specifications
All processor bus timings are synchronous; input setup/hold and output delay are
given in respect to the rising edge of a reference clock, FB_CLK. The FB_CLK
frequency may be the same as the internal system bus frequency or an integer divider
of that frequency.
The following timing numbers indicate when data is latched or driven onto the
external bus, relative to the Flexbus output clock (FB_CLK). All other timing
relationships can be derived from these values.
