5.1 Analog-to-Digital Converter (ADC)

RL78 and MSPM0 both offer ADC peripherals to convert analog signals to a digital equivalent. Both device families feature a 12-bit ADC. In addition, RL78 I series offers 24-bit delta-sigma ADC, which is not in this discussion, and MSP430F676x can be considered. Table 5-1 and Table 5-2 compare the different features and modes of the ADCs.

ADC external reference is not be supported by MSPM0C1103 and MSPM0C1104 device.

Table 5-2 Conversion Modes
RL78 (1) MSPM0 Comments
Select Mode, One-shot Conversion Mode / Single Scan Mode Single Channel Single Conversion ADC samples and converts a single channel once
Scan Mode, One-shot Conversion Mode / Single Scan Mode Sequence of Channels Conversion ADC samples a sequence of channels and converts once.
Select Mode, Sequential Conversion Mode / Continuous Scan Mode Repeat Single Channel Conversion Repeat single channel continuously samples and converts one channel
Scan Mode, Sequential Conversion Mode / Continuous Scan Mode Repeat Sequence of Channels Conversion Samples and converts a sequence of channels then repeats the same sequence
(1) The name of RL78 ADC conversion mode varies per device, here is two types of naming used '/' split.
