Section 15 A/D Converter
15. 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 15.1.
15.1 Features
⢠10-bit resolution
⢠Input channels
⯠8 channels (two independent A/D conversion modules)
⢠Conversion time: 5.4 µs per channel (at PÏ = 25-MHz operation), 6.7µs per channel (at PÏ =
20-MHz operation)
⢠Three operating modes
⯠Single mode: Single-channel A/D conversion
⯠Continuous scan mode: Continuous A/D conversion on 1 to 4 channels
⯠Single-cycle scan mode: Single-cycle 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)
⯠External trigger signal
⢠Interrupt request
⯠An A/D conversion end interrupt request (ADI) can be generated
⢠Module standby mode can be set
