Section 13 A/D Converter
This LSI includes a successive approximation type 10-bit A/D converter. The block diagram of the
A/D converter is shown in figure 13.1.
13.1 Features
• 10-bit resolution
• Input channels
 12 channels (three independent A/D conversion modules)
• Conversion time: 6.7 µs per channel (at Pφ = 20 MHz operation), 5.4 µs (during Pφ = 25 MHz
operation)
• Three operating modes
 Single mode: Single-channel A/D conversion
 Continuous scan mode: Repetitive A/D conversion on 1 to 4 channels
 Single-cycle scan mode: Continuous A/D conversion on 1 to 4 channels
• Data registers
 Conversion results are held in a 16-bit data register for each channel
• Sample and hold function
• Three methods for conversion start
 Software
 Conversion start trigger from multifunction timer pulse unit (MTU) or motor management
timer (MMT)
 External trigger signal
• Interrupt request
 An A/D conversion end interrupt request (ADI) can be generated
• Module stop mode can be set
