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
