6.3 Pin types
6.3.1 POWER SUPPLY PINS
There are 6 different power supply domains (see Fig.3):
• Digital core circuit (2.5 V): VDD3V1/VSS3V1
• Digital periphery circuit (3.0 V): VDD3V2/VSS3V2 and
VDD3V3/VSS3V3
• PLL circuits and crystal oscillator (2.5 V): VDDPLL and
VSSPLL
• Analog circuits (2.5 V): VDDA and VSSA.
All VSS pins must be connected to the same ground plane
on the Printed-Circuit Board (PCB). All 2.5 V VDD pins
must be connected to the same power supply. All VDD pins
have to be separately decoupled, according to Chapter 18.
6.3.2 ANALOG PINS
• ana: full ESD protected analog I/O pad (double
protection diode).
6.3.3 DIGITAL PINS
• ucp4mthuwh: 4 mA 80C51 I/O pins
• uceda4mtuwh: 4 mA 80C51 I/O pins with input enable
• iptd: input pad buffer; pull-down
• ipth: input pad buffer with Schmitt trigger
• ops10c: output pad; push-pull; 4 mA output drive; 10 ns
slew control
• I2C400k: bidirectional open-drain I2C-bus compatible
pad.
