H8S/2427, H8S/2427R, H8S/2425 Group
This LSI includes two units (units 0 and 1) of successive approximation type 10-bit A/D
converter. In the H8S/2427 Group and H8S/2427R Group, the A/D converter units 0 and 1 allow
up to eight analog input channels to be selected. In the H8S/2425 Group, unit 0 allows up to eight
analog input channels to be selected while unit 1 allows up to two channels.
Figures 18.1 and 18.2 show block diagrams of the A/D converter units 0 and 1, respectively.
18.1
• 10-bit resolution
• Input channels:
• Conversion cycle: 64 cycles or 40 cycles (A/D conversion clock)
• Two kinds of operating modes
• Separate A/D conversion clock specifiable for each unit (φ, φ/2, or φ/4)
• Eight data registers for A/D converter unit 0 and eight data registers for unit 1*
• Sample and hold functionality
• Three types of conversion start
• Interrupt source
• Module stop state specifiable
Notes: 1. Continuous A/D conversion on 1 to 2 channels in the H8S/2425 Group.

H8S/2427 Group and H8S/2427R Group: Eight channels (total of 16 channels for the two
units)
H8S/2425 Group: Eight channels for unit 0 and two channels for unit 1 (total of 10 channels
for the two units)
⎯ Single mode: Single-channel A/D conversion
⎯ Scan mode: Continuous A/D conversion on 1 to 4 channels, or 1 to 8 channels*
data registers for the two units)
Results of A/D conversion are held in a 16-bit data register for each channel.
Conversion can be started by software, a conversion start trigger by the 16-bit timer pulse unit
(TPU) or 8-bit timer (TMR), or an external trigger signal.
A/D conversion end interrupt (ADI) request can be generated.
2. Two data registers for unit 1 (total of ten data registers for the two units) in the
