LM3S610_06 Datasheet, PDF (24/396 Pages) List of Unclassifed Manufacturers – Microcontroller

Architectural Overview
• Synchronization of timers in the PWM generator blocks
• Synchronization of timer/comparator updates across the PWM generator blocks
• Interrupt status summary of the PWM generator blocks
– Can initiate an ADC sample sequence
„ GPIOs
– 6 to 34 GPIOs, depending on configuration
– 5-V-tolerant input/outputs
– Programmable interrupt generation as either edge-triggered or level-sensitive
– Bit masking in both read and write operations through address lines
– Can initiate an ADC sample sequence
– Programmable control for GPIO pad configuration:
• Weak pull-up or pull-down resistors
• 2-mA, 4-mA, and 8-mA pad drive
• Slew rate control for the 8-mA drive
• Open drain enables
• Digital input enables
„ 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
– User-enabled LDO unregulated voltage detection and automatic reset
– 3.3-V supply brownout detection and reporting via interrupt or reset
– On-chip temperature sensor
„ 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
„ Additional Features
– Six reset sources
– Programmable clock source control
– Clock gating to individual peripherals for power savings
– IEEE 1149.1-1990 compliant Test Access Port (TAP) controller
– Debug access via JTAG and Serial Wire interfaces
