Product Description

The Stellaris® LM3S817 microcontroller is based on the ARM® Cortex™-M3 controller core operating at up to 50 MHz, with 64 kB flash and 8 kB SRAM. The LM3S817 also features real-time industrial connectivity, with an SSI / SPI controller, and 2 UARTs. The LM3S817 microcontroller also features advanced motion control features, including 6 motion-control PWM outputs with dead-band and 1 fault protection inputs for low-latency shutdown. The microcontroller also features intelligent analog capability, including 1 analog comparators and 6 channels of highly accurate 10-bit analog-to-digital conversion - with the ability to sample at speeds of 1M samples per second. Finally, the LM3S817 microcontroller provides a 24-bit systick timer, 3 32-bit or 6 16-bit general-purpose timers, a watchdog timer, a low drop-out voltage regulator so that only one supply voltage is required, brown-out reset, power-on reset controller, and up to 30 GPIOs.
32-bit ARM® Cortex™-M3 50-MHz processor core with System Timer (SysTick), integrated Nested Vectored Interrupt Controller (NVIC), Memory Protection Unit (MPU), and Thumb-2 instruction set
Full-featured debug solution with debug access via JTAG and Serial Wire interfaces, and IEEE 1149.1-1990 compliant Test Access Port (TAP) controller
64 KB single-cycle flash and 8 KB single-cycle SRAM
1-30 GPIOs (depending on configuration) with programmable control for GPIO interrupts and pad configuration
ARM FiRM-compliant Watchdog Timer ; plus three General-Purpose Timer Modules (GPTM), each of which provides two 16-bit timers/counters and can be configured to operate independently
10-bit Analog-to-Digital Converter (ADC) with six analog input channels and a sample rate of one million samples/second
Two fully programmable 16C550-type UARTs
Synchronous Serial Interface (SSI), supporting operation for Freescale SPI, MICROWIRE, or Texas Instruments synchronous serial interfaces
One integrated analog comparator configurable for output to initiate an ADC sample sequence, drive an output pin or generate an interrupt
Three 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
Industrial and extended temperature RoHS-compliant 48-pin LQFP and 48-pin QFN package
