Power Supply
The TC1762 has several power supply lines for different voltage classes:
• 1.5 V: Core logic, oscillator and A/D converter supply
• 3.3 V: I/O ports, Flash memories, oscillator, and A/D converter supply with reference
voltages
Figure 3-16 shows the power supply concept of the TC1762 with the power supply pins
and its connections to the functional units.
