The Stellaris Family of ARM® Cortex™-M3 microcontrollers features intelligent analog capability, including up to 8 channels of ADC operating at up to 1 Msps. Each intelligent ADC channel features a sequencer to minimize CPU utilization, ensuring that the CPU is used for data processing - not data collection.
