Section 22 A/D Converter
This LSI includes a successive-approximation-type 10-bit A/D converter that allows up to six
analog input channels and up to eight digital input channels to be selected.
A/D conversion for digital input is effective as a comparator in multiple input testing.
22.1
Features
•
10-bit resolution
•
Ι
nput channels: six analog input channels and eight digital input channels
•
Analog conversion voltage range can be specified using the reference power supply voltage
pin (AVref) as an analog reference voltage.
•
Conversion time: Max. 5.36 µs per channel (at 25-MHz operation)
•
Two kinds of 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 kinds of conversion start
Software, 8-bit timer (TMR) conversion start trigger, or external trigger signal.
•
Interrupt request
A/D conversion end interrupt (ADI) request can be generated
•
Module stop mode can be set
A block diagram of the A/D converter is shown in figure 22.1.
