Electrical Characteristics
MCF5213 ColdFire Microcontroller, Rev. 3
Freescale Semiconductor 25
1.15 Power and Ground Pins
The pins described in Table 18 provide system power and ground to the chip. Multiple pins are provided for adequate current
capability. All power supply pins must have adequate bypass capacitance for high-frequency noise suppression.

Table 18. Power and Ground Pins
Signal Name Abbreviation Function
PLL Analog Supply VDDPLL,
VSSPLL
Dedicated power supply signals to isolate the sensitive PLL analog
circuitry from the normal levels of noise present on the digital power
supply.
Positive Supply VDD These pins supply positive power to the core logic.
Ground VSS This pin is the negative supply (ground) to the chip.
