8/10-bit A/D converter
The feature of 8/10-bit A/D converter is shown as follows.
conversion time : 3.1
μs minimum per 1 channel
(78 machine cycle/at machine clock 25 MHz/including the sampling time)
Sampling time : 2.0
μs minimum per 1channel
(50 machine cycle/at machine clock 25 MHz)
Uses RC-type successive approximation conversion method with a sample & hold circuit
8-bit resolution or 10-bit resolution can be select.
12 channel program-selectable analog inputs.
Single conversion mode
: Convert specified 1 channel
Scan conversion mode
: Continuous plural channels (maximum 12 channels can be programmed) are
converted.
Continuous conversion mode : Selected channel converted continuously.
Stop conversion time
: Perform conversion for one channel, then pause it to wait for the next activation
trigger (synchronizes the conversion start timing)
EI2OS can be activated by outputting the interrupt request when the A/D conversion completes.
If the A/D conversion is performed under the condition of the interrupt enable, the converting data will be
protected.
Selectable conversion activation trigger : Software, or reload timer (rising edge)
