Section 17 A/D Converter

This LSI includes a successive approximation type 10-bit A/D converter that allows up to eight

analog input channels to be selected. A block diagram of the A/D converter is shown in figure

17.1.

17.1

Features

• 10-bit resolution

• Eight input channels

• Conversion time: 9.6 µs per channel (at 13.5 MHz operation)

• Two operating modes

Single mode: Single-channel A/D conversion

Scan mode: Continuous A/D conversion on 1 to 4 channels

• Four data registers

Conversion results are held in a 16-bit data register for each channel

• Sample and hold function

• Three methods conversion start

Software

Timer (TPU or 8-bit timer) conversion start trigger

External trigger signal

• Interrupt request

An A/D conversion end interrupt request (ADI) can be generated

• Module stop mode can be set

• Selectable range voltages of analog inputs

The range of voltages of analog inputs to be converted can be specified using the Vref signal as

the analog reference voltage.
