Notes:
(5) t
WC
is the minimum cycle time to be allowed from the system perspective unless polling techniques are used. It is the maximum
time the device requires to automatically complete the internal write operation.
(6) t
WPH
is the normal page write operation
WE
recovery time. t
WPH2
is the
WE
recovery time needed only after the end of issuing
the three-byte SDP command sequence and before writing the first byte of data to the array. Refer to Figure 6 which illustrates
the t
WPH2
requirement.
(7) For faster t
WC
and t
BLC
times, refer to X28HC64.
