System Design Information
SENSEVSS_Core1 and needs to be connected to ground with a weak (2–10 kΩ) pull down resistor.
Likewise, AVDD_Core1 needs to be pulled to ground as shown in Figure 64.
The mechanical drawing for the single core device is located in Section 16.2, “Mechanical Dimensions of
For other pin pull-up or pull-down recommendations of signals, please see Section 17, “Signal Listings.”

Output Buffer DC Impedance
The MPC8640 drivers are characterized over process, voltage, and temperature. For all buses, the driver
is a push-pull single-ended driver type (open drain for I2C).
To measure Z0 for the single-ended drivers, an external resistor is connected from the chip pad to OVDD
or GND. Then, the value of each resistor is varied until the pad voltage is OVDD/2 (see Figure 66). The
output impedance is the average of two components, the resistances of the pull-up and pull-down devices.
When data is held high, SW1 is closed (SW2 is open) and RP is trimmed until the voltage at the pad equals
OVDD/2. RP then becomes the resistance of the pull-up devices. RP and RN are designed to be close to each
other in value. Then, Z0 = (RP + RN) ÷ 2.
Figure 66. Driver Impedance Measurement
Table 73 summarizes the signal impedance targets. The driver impedances are targeted at minimum VDD,
nominal OVDD, 105 °C.
