The following tables and figures refer to the maximum and typical standby currents for
the MT45W4MW16PFA device. The typical values shown in Figure 13 are measured with
the appropriate PAR and TCR settings. The maximum values shown in Table 6 and
Table 7 are measured with the relevant TCR bits set in the configuration register.
