Description
AI
The Stellaris® LM3S8970 microcontroller is based on the ARM® Cortex™-M3 controller core operating at up to 50 MHz, with 256 kB flash and 64 kB SRAM. The LM3S8970 also features real-time industrial connectivity, with a 10/100 Ethernet MAC/PHY, 3 CAN controllers, 2 SSI / SPI controllers, an I2C interface, and 2 UARTs, as well as hardware-assisted support for synchronized industrial networks utilizing the IEEE 1588 Precision Time Protocol (PTP). Finally, the LM3S8970 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 46 GPIOs.
