Stellaris® LM3S613 Microcontroller
â Two PWM generator blocks, each with one 16-bit counter, two PWM comparators, a PWM
signal generator, a dead-band generator, and an interrupt/ADC-trigger selector
â One fault input in hardware to promote low-latency shutdown
â One 16-bit counter
⢠Runs in Down or Up/Down mode
⢠Output frequency controlled by a 16-bit load value
⢠Load value updates can be synchronized
⢠Produces output signals at zero and load value
â Two PWM comparators
⢠Comparator value updates can be synchronized
⢠Produces output signals on match
â PWM generator
⢠Output PWM signal is constructed based on actions taken as a result of the counter and
PWM comparator output signals
⢠Produces two independent PWM signals
â Dead-band generator
⢠Produces two PWM signals with programmable dead-band delays suitable for driving a
half-H bridge
⢠Can be bypassed, leaving input PWM signals unmodified
â Flexible output control block with PWM output enable of each PWM signal
⢠PWM output enable of each PWM signal
⢠Optional output inversion of each PWM signal (polarity control)
⢠Optional fault handling for each PWM signal
⢠Synchronization of timers in the PWM generator blocks
⢠Interrupt status summary of the PWM generator blocks
â Can initiate an ADC sample sequence
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 Low-power options on controller: Sleep and Deep-sleep modes
â Low-power options for peripherals: software controls shutdown of individual peripherals
