Analog-to-Digital Converter (ADC)
25.1 Overview
25.1.1 Device-specific features
• 10-bit resolution
• 36 channels (depending on package type), expandable to 64 channels via external multiplexing
— As many as 16 precision channels
— As many as 20 standard channels, 4 being expandable to as many as 32 external channels
• Address decoder signal generation (alternate functions MA[2:0]) to control external multiplexers
• Individual conversion registers for each channel (internal and external)
• 3 different sampling and conversion time registers CTR[0:2] (internal precision channels, standard
channels, external channels)
• As many as 64 data registers for storing converted data. Conversion information, such as mode of
operation (normal, injected or CTU), is associated to data value.
• Conversion triggering sources:
— Software
—CTU
— PIT channel 2 (for injected conversion)
• 4 analog watchdogs
— Interrupt capability
— Allow continuous hardware monitoring of 4 analog input channels
• Presampling (V
SS
and V
DD
)
• Conversions on external channels managed in the same way as internal channels, making it
transparent to the application
• One Shot/Scan Modes
• Chain Injection Mode
• Power-down mode
• 2 different Abort functions allow to abort either single-channel conversion or chain conversion
• Auto-clock-off
