TC1796
Functional Description
for the oscillator operation. Please refer to the minimum and maximum values of
the negative resistance specified by the crystal supplier.

Power Supply
The TC1796 has several power supply lines for different voltage classes:
• 1.5 V: Core logic and memory, oscillator, and A/D converter supply
• 3.3 V: I/O ports, Flash memories, oscillator, and A/D converter supply with reference
voltages
• 2.3 V to 3.3 V: External bus interface supply
Figure 21 shows the power supply concept of the TC1796 with the power supply pins
and its connections to the functional units.
