LM3S5652 Datasheet, PDF (45/848 Pages) Texas Instruments – Stellaris® LM3S5652 Microcontroller

Stellaris® LM3S5652 Microcontroller
– 4 transfer types: Control, Interrupt, Bulk, and Isochronous
– 8 endpoints
• 1 dedicated control IN endpoint and 1 dedicated control OUT endpoint
• 3 configurable IN endpoints and 3 configurable OUT endpoints
– 2 KB dedicated endpoint memory
• Direct memory access (DMA)
• One endpoint may be defined for double-buffered 1023-byte isochronous packet size
■ Analog Comparators
– One integrated analog comparator
– 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
– Hibernation module handles the power-up/down 3.3 V sequencing and control for the core
digital logic and analog circuits
– 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
