Section 19 A/D Converter (ADC)
This LSI includes a successive approximation type 10-bit A/D converter.
19.1 Features
• 10-bit resolution
• Input channels
⎯ 8 channels in SH7083/SH7084/SH7085 (two independent A/D conversion modules)
⎯ 16 channels in SH7086 (three independent A/D conversion modules)
• Conversion time: 2.0 µs per channel (operation when Pφ = 25 MHz)
• Three operating modes
⎯ Single mode: Single-channel A/D conversion
⎯ Continuous scan mode: Repetitive A/D conversion on up to four channels in
SH7083/SH7084/SH7085 and up to eight channels in SH7086
⎯ Single-cycle scan mode: Continuous A/D conversion on up to four channels in
SH7083/SH7084/SH7085 and up to eight channels in SH7086
• Data registers
⎯ Conversion results are held in a 16-bit data register for each channel
• Sample-and-hold function
• Three methods for conversion start
⎯ Software
⎯ Conversion start trigger from multifunction timer pulse unit 2 (MTU2) or multifunction
timer pulse unit 2S (MTU2S)
⎯ External trigger signal
• Interrupt request
⎯ An A/D conversion end interrupt request (ADI) can be generated
• Module standby mode can be set
