信息

The Stellaris® LM3S818 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 LM3S818 also features real-time industrial connectivity, with an SSI / SPI controller, and 2 UARTs.The LM3S818 microcontroller also features advanced motion control features, including 6 motion-control PWM outputs with dead-band, a quadrature encoder input for precise position monitoring,and a fault protection input 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 LM3S818 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.

技术参数

  • 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

  • 0-30 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

  • Quadrature Encoder Interface (QEI) featuring position integrator to track encoder position and velocity capture using built-in timer

  • Industrial and extended temperature RoHS-compliant 48-pin LQFP and 48-pin QFN package
