3.13.7 CFM Timing Specifications
Table 35
lists the time required to execute various operations described in the
Section 3.13.1
through
Section 3.13.6
. For operating conditions other than those assumed below,
Equation 19
through
Equation 29
must be used to calculate the timing for specific commands under those conditions.

NOTES:
1. Subject to restrictions in
Table 19
and
Table 20
for operating characteristics of the oscillator and PLL.
2. Minimum erase and programming times are achieved with the indicated maximum
f
SYS
(which is
f
IPS
×
2, and subject to the
limits of
Table 19
and
Table 20
) and corresponding maximum
f
NVMOP
. Maximum erase and programming times are
dependent on the combination of
f
NVMOP
and
f
IPS
; values shown are calculated for
f
IPS
= 2 MHz and
f
NVMOP
= 154 KHz
.
3. Minimum blank check or page erase verify time assumes the first word in the array is blank and the second is not. Maximum
blank check or page erase verify time assumes the entire block or page is blank.
4. Data signature timing is dependant on the number of words or half-words compressed for the program and data arrays,
respectively. Minimum time is for two words or half-words; maximum time is for the entire array.
