LM3S6422 Datasheet, PDF (35/609 Pages) Texas Instruments – Stellaris® LM3S6422 Microcontroller

Stellaris^® LM3S6422 Microcontroller
• User-configurable interrupts
– Physical media manipulation
• Automatic MDI/MDI-X cross-over correction
• Register-programmable transmit amplitude
• Automatic polarity correction and 10BASE-T signal reception
■ Analog Comparators
– Two independent integrated analog comparators
– Configurable for output to drive an output pin, generate an interrupt, or initiate an ADC sample
sequence
– Compare external pin input to external pin input or to internal programmable voltage reference
– Compare a test voltage against any one of these voltages
• An individual external reference voltage
• A shared single external reference voltage
• A shared internal reference voltage
■ Power
– On-chip Low Drop-Out (LDO) voltage regulator, with programmable output user-adjustable
from 2.25 V to 2.75 V
– Low-power options on controller: Sleep and Deep-sleep modes
– Low-power options for peripherals: software controls shutdown of individual peripherals
– 3.3-V supply brown-out detection and reporting via interrupt or reset
■ Flexible Reset Sources
– Power-on reset (POR)
– Reset pin assertion
– Brown-out (BOR) detector alerts to system power drops
– Software reset
– Watchdog timer reset
– Internal low drop-out (LDO) regulator output goes unregulated
■ Industrial temperature 100-pin RoHS-compliant LQFP package
■ Industrial-range 108-ball RoHS-compliant BGA package
