Freescale Semiconductor

VDD15c

1.5 V

Provides operating voltage and ground for the MCU core

logic, including the MCU core, all peripherals, and all

RAMs. This allows the supply voltage to the core to be

bypassed independently. When not bypassed, the core

supply is generated by the internal voltage regulators, and

these pins are used for an external bypass capacitor.

VSS15c

VDD33

124

3.3 V

Provides operating voltage and ground for the Flash and

I/O pre-drivers. This allows the supply voltage to the Flash

and I/O pre-drivers to be bypassed independently. When

not bypassed, the Flash and I/O pre-driver supply is

generated by the internal voltage regulators, and these pins

are used for an external bypass capacitor.

VSS33

125

VDDR

5.0 V

Supplies external power for all internal voltage regulation.

VDDX1-4,6-11

10,20,49,63,

67,80,120

14,34,

58,87

5.0 V

Supplies external power and ground for the I/O drivers.

VSSX1-11

9,19,30,48,

62,79,95,119

13,33,57,

63,86

0 V

VDDX5

5.0 V

Supplies external power and ground for the I/O drivers, as

well as the control voltage for all internal regulator pass

transistors.

VDDA

109

5.0 V

Operating voltage and ground for the analog-to-digital

converters and the reference for the internal voltage

regulator, allows the supply voltage to the A/D to be

bypassed independently.

VSSA

112

0 V

VRH

110

5.0 V

Supplies external reference voltages for the

analog-to-digital converter.

VRL

111

0 V

VDDPLL

3.3 V

Provides operating voltage and ground for the

Phased-Locked Loop and Oscillator. This allows the supply

voltage to the PLL and Oscillator to be bypassed

independently. When not bypassed, the PLL and Oscillator

supply is generated by the internal voltage regulators, and

these pins are used for an external bypass capacitor.

VSSPLL

0 V

VPP

5.0V

Supplies external power for program and erase of the

Flash.

VSS-TEST

Pin must be tied to Ground on all applications.
