LM3S5747 Stellaris 微处理器

The Stellaris(R) LM3S5747 microcontroller is based on the ARM(R) CortexTM-M3 controller core operating at up to 50 MHz, with 128 kB flash, 64 kB SRAM, a 32-ch DMA, and ROM preloaded with the StellarisWare Driver Library and BootLoader. The LM3S5747 also features real-time industrial connectivity, with a CAN controller, USB 2.0 Full Speed Host/Device, an SSI / SPI controller, an I2C interface, and a UART. The LM3S5747 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 .8 channels of highly accurate 10-bit analog-to-digital conversion - with the ability to sample at speeds of 500K samples per second.
