LM3S1969 Stellaris 微处理器

The Stellaris(R) LM3S1969 microcontroller is based on the ARM(R) CortexTM-M3 controller core operating at up to 50 MHz, with 256 kB flash and 64 kB SRAM. The LM3S1969 also features real-time industrial connectivity, with 2 SSI / SPI controllers, 2 I2C interfaces, and 3 UARTs. The LM3S1969 microcontroller also features advanced motion control features, including 6 motion-control PWM outputs with dead-band, two quadrature encoder inputs for precise position monitoring, and 1 fault protection inputs for low-latency shutdown. The microcontroller also features intelligent analog capability, including 3 analog comparators and 8 channels of highly accurate 10-bit analog-to-digital conversion - with the ability to sample at speeds of 1M samples per second.
