19.1
The H8S/2138 Group and H8S/2134 Group incorporate a 10-bit successive-approximations A/D
converter that allows up to eight analog input channels to be selected.
In addition to the eight analog input channels, up to 8 channels of digital input can be selected for
A/D conversion. Since the conversion precision falls to the equivalent of 6-bit resolution when
digital input is selected, digital input is ideal for use by a comparator identifying multi-valued
inputs, for example.
19.1.1
A/D converter features are listed below.
10-bit resolution
Eight (analog) or 8 (digital) input channels
Settable analog conversion voltage range
High-speed conversion
Choice of single mode or scan mode
Four data registers
Sample and hold function
Three kinds of conversion start
A/D conversion end interrupt generation
The analog conversion voltage range is set using the analog power supply voltage pin
(AVcc) as the analog reference voltage
Minimum conversion time: 6.7 µs per channel (at 20-MHz operation)
Single mode: Single-channel A/D conversion
Scan mode:
Conversion results are held in a 16-bit data register for each channel
Choice of software or timer conversion start trigger (8-bit timer), or ADTRG pin
An A/D conversion end interrupt (ADI) request can be generated at the end of A/D
conversion
Overview
Features
Continuous A/D conversion on 1 to 4 channels
