Stellaris® LM3S5739 Microcontroller
â USB Device or Host mode
â Integrated PHY
â 4 transfer types: Control, Interrupt, Bulk, and Isochronous
â 8 endpoints
⢠1 dedicated control IN endpoint and 1 dedicated control OUT endpoint
⢠3 configurable IN endpoints and 3 configurable OUT endpoints
â 2 KB dedicated endpoint memory
⢠Direct memory access (DMA)
⢠One endpoint may be defined for double-buffered 1023-byte isochronous packet size
â Analog Comparators
â Two independent integrated analog comparators
â Configurable for output to drive an output pin, generate an interrupt, or initiate an ADC sample
sequence
â Compare external pin input to external pin input or to internal programmable voltage reference
â 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
â Power
â On-chip Low Drop-Out (LDO) voltage regulator, with programmable output user-adjustable
from 2.25 V to 2.75 V
â Hibernation module handles the power-up/down 3.3 V sequencing and control for the core
digital logic and analog circuits
â Low-power options on controller: Sleep and Deep-sleep modes
â Low-power options for peripherals: software controls shutdown of individual peripherals
â 3.3-V supply brown-out detection and reporting via interrupt or reset
â Flexible Reset Sources
â Power-on reset (POR)
â Reset pin assertion
â Brown-out (BOR) detector alerts to system power drops
