The LM3S2B00 Series of Stellaris MCUs features Controller Area Network with 256K bytes of flash and 96K bytes of SRAM. In addition to several product enhancements, the LM3S2B00 Series adds new features, such as a versatile External Peripheral Interface (with modes to support SDRAM, SRAM/Flash, Host-Bus, and M2M), an Integrated Interchip Sound (I2S) Interface, simultaneous dual ADC capability, a second watchdog timer with independent clock for safety critical applications (supported by the IEC 60730 library addition to the StellarisWare™ Library), and a 16 MHz software-trimmed 1% Precision Oscillator.

The Stellaris® LM3S2B93 microcontroller is based on the ARM® Cortex™-M3 controller core operating at up to 80 MHz, with 256 kB flash, 96 kB SRAM, a 32-ch DMA, a 32-bit external peripheral interface, a 16MHz internal precision oscillator, and ROM preloaded with the StellarisWare Driver Library, Boot Loader, AES encryption lookup tables, and a cyclical redundancy check (CRC) function. The LM3S2B93 also features real-time industrial connectivity, with 2 CAN controllers, 2 SSI / SPI controllers, 2 I2C interfaces, an I2S interface, and 3 UARTs. The LM3S2B93 microcontroller also features advanced motion control features, including 8 motion-control PWM outputs with dead-band, two quadrature encoder inputs for precise position monitoring, and 4 fault protection inputs for low-latency shutdown. The microcontroller also features intelligent analog capability, including 3 analog comparators and 16 channels of highly accurate 10-bit analog-to-digital conversion - with the ability to sample two channels simultaneously at speeds of 1M samples per second. Finally, the LM3S2B93 microcontroller provides 16 digital comparators, a 24-bit systick timer, four 32-bit or eight 16-bit general-purpose timers, 2 watchdog timers, a battery-backed hibernation module with RTC and 256 bytes of non-volatile state-saving memory, a low drop-out voltage regulator so that only one supply voltage is required, brown-out reset, power-on reset controller, and up to 60 GPIOs.
