Section 27

A/D Converter

This LSI includes a 10-bit successive-approximation A/D converter allowing selection of up to

four analog input channels.

27.1

Features

A/D converter features are listed below.

• 10-bit resolution

• Four input channels

• High-speed conversion

 Minimum conversion time: 15 µs per channel

• Three conversion modes

 Single mode: A/D conversion on one channel

 Multi mode: A/D conversion on one to four channels

 Scan mode: Continuous A/D conversion on one to four channels

• Four 16-bit data registers

 A/D conversion results are transferred for storage into 16-bit data registers corresponding

to the channels.

• Sample-and-hold function

• A/D interrupt requested at the end of conversion

 At the end of A/D conversion, an A/D end interrupt (ADI) can be requested.

• A/D conversion can be externally triggered
