TI does not recommend using this part in a new design. This product continues to be in production to support existing customers. TI suggests designers consider Control + Automation as an alternative family or series of devices for use in new designs.
The Stellaris® LM3S1607 microcontroller is based on the ARM® Cortex™-M3 controller core operating at up to 50 MHz, with 128 kB flash, 32 kB SRAM, a 32-ch DMA, and ROM preloaded with the StellarisWare Driver Library and BootLoader. The LM3S1607 also features real-time industrial connectivity, with an SSI / SPI controller, 2 I2C interfaces, and 3 UARTs. 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. Finally, the LM3S1607 microcontroller provides a 24-bit systick timer, 4 32-bit or 8 16-bit general-purpose timers, a watchdog timer, 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 33 GPIOs.
