LM3S5732 (NRND) Stellaris LM3S Microcontroller


Not Recommended for New Designs (NRND)

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 TM4C12x as an alternative family or series of devices for use in new designs.


The Stellaris® LM3S5732 microcontroller is based on the ARM® Cortex™-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 LM3S5732 also features real-time industrial connectivity, with a CAN controller, USB 2.0 Full Speed Host/Device, an SSI / SPI controller, 2 I2C interfaces, and 2 UARTs. The microcontroller also features intelligent analog capability, including .6 channels of highly accurate 10-bit analog-to-digital conversion - with the ability to sample at speeds of 500K samples per second. Finally, the LM3S5732 microcontroller provides a 24-bit systick timer, 3 32-bit or 6 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.
