TC1197
Introduction
• Input voltage range from 0V to analog supply voltage
• Analog supply voltage range from 3.3 V to 5 V (single supply)
(5V nominal supply voltage, performance degradation accepted for lower voltages)
• Input multiplexer width of 16 possible analog input channels (not all of them are
necessarily available on pins)
• Performance for 12 bit resolution (@f_ADCI = 10 MHz):
- conversion time about 2µs, TUE¹⁾ of ±4 LSB₁₂ @ operating voltage 5 V
- conversion time about 2µs, TUE of ±4 LSB₁₂ @ operating voltage 3.3 V
• V_AREF and 1 alternative reference input at channel 0
• Programmable sample time (in periods of f_ADCI)
• Wide range of accepted analog clock frequencies f_ADCI
• Multiplexer test mode (channel 7 input can be connected to ground via a resistor for
test purposes during run time by specific control bit)
• Power saving mechanisms
Features of the digital part of each ADC kernel:
• Independent result registers (16 independent registers)
• 5 conversion request sources (e.g. for external events, auto-scan, programmable
sequence, etc.)
• Synchronization of the ADC kernels for concurrent conversion starts
• Control an external analog multiplexer, respecting the additional set up time
• Programmable sampling times for different channels
• Possibility to cancel running conversions on demand with automatic restart
• Flexible interrupt generation (possibility of DMA support)
• Limit checking to reduce interrupt load
• Programmable data reduction filter by adding conversion results
• Support of conversion data FIFO
• Support of suspend and power down modes
• Individually programmable reference selection for each channel (with exception of
dedicated channels always referring to V_AREF)
1) This value reflects the ADC module capability in an adapted electrical environment, e.g. characterized by
“clean” routing of analog and digital signals and separation of analog and digital PCB areas, low noise on
analog power supply (< 30mV), low switching activity of digital pins near to the ADC, etc.
