2200's

Featuring an integrated Controller Area Network interface, 64K bytes of single cycle flash, 32K bytes of single cycle SRAM, and 50 MHz performance, the Stellaris LM3S2200 Series microcontrollers are perfect for cost-effective embedded control applications requiring industrial connectivity. Based on the ARM® Cortex™-M3 controller core, the Stellaris® LM3S2200 Series of microcontrollers also features a 32-ch DMA controller and a host of other serial interfaces, such as an SSI / SPI controller, an I2C interface, and a UART. Analog features in the LM3S2200 Series include a 10-bit analog-to-digital converter (ADC) with 6 input channels (+/- 1 LSb of accuracy) at 1Msps. The LM3S2200 Series was also designed for meticulous motion control, with an integrated motion-control Pulse Width Modulation (PWM) module with 8 output channels.
