On-chip Flash Operation
The XC164D’s Flash module delivers data within a fixed access time (see Table 15).
Accesses to the Flash module are controlled by the PMI and take 1 + WS clock cycles,
where WS is the number of Flash access waitstates selected via bitfield WSFLASH in
register IMBCTRL. The resulting duration of the access phase must cover the access
time
t
ACC of the Flash array. Therefore, the required Flash waitstates depend on the
available speed grade as well as on the actual system frequency.
Note: The Flash access waitstates only affect non-sequential accesses. Due to
prefetching mechanisms, the performance for sequential accesses (depending on
the software structure) is only partially influenced by waitstates.
In typical applications, eliminating one waitstate increases the average
performance by 5% … 15%.
Example: For an operating frequency of 40 MHz (clock cycle = 25 ns), Standard devices
must be operated with 2 waitstates: ((2 + 1)
× 25 ns) ≥ 70 ns.
indicates the interrelation of waitstates, system frequency, and speed grade.
Note: The maximum achievable system frequency is limited by the properties of the
respective derivative, i.e. 40 MHz (or 20 MHz for xxx-32F20F devices).
