28.1 Overview
28.1.1
• VRL outputs the operating voltage, V
• VRX outputs the operating voltage, V
28.1.2
28.1.3
This LSI includes a regulated power supply for the internal logic (VRL) and a regulated power supply for low-speed
oscillation (VRX).
The VRL outputs the operating voltage, V
The VRX outputs the operating voltage, V
For the circuit configuration of the power supplies (AVDD, AVSS) for the analog circuits, see Chapter 25, “Successive
Approximation Type A/D converter”.
For the circuit configuration of the power supplies for LCD (VL1 to VL4), see Chapter 26, “LCD Driver”.
Figure 28-1 shows the configuration of the power supply circuit.
