Electrical Characteristics
2.1.3
Output Driver Characteristics
Table 3 provides information on the characteristics of the output driver strengths.
2.1.4
Input Capacitance Specification
Table 4 describes the input capacitance for the SYS_CLK_IN pin in the MPC8306S.
2.2
Power Sequencing
The device does not require the core supply voltage (VDD) and IO supply voltages (GVDD and OVDD) to
be applied in any particular order. Note that during power ramp-up, before the power supplies are stable
and if the I/O voltages are supplied before the core voltage, there might be a period of time that all input
and output pins are actively driven and cause contention and excessive current. In order to avoid actively
driving the I/O pins and to eliminate excessive current draw, apply the core voltage (VDD) before the I/O
voltage (GVDD and OVDD) and assert PORESET before the power supplies fully ramp up. In the case
where the core voltage is applied first, the core voltage supply must rise to 90% of its nominal value before
the I/O supplies reach 0.7 V; see Figure 3. Once both the power supplies (I/O voltage and core voltage) are
stable, wait for a minimum of 32 clock cycles before negating PORESET.
NOTE
There is no specific power down sequence requirement for the device. I/O voltage supplies (GVDD and
OVDD) do not have any ordering requirements with respect to one another.
