Original Press Release:



LM3S9997



The Stellaris® LM3S9997 microcontroller is based on the ARM® Cortex?-M3 controller core operating at up to 80 MHz, with 256 kB flash, 64 kB SRAM, a 32-ch DMA, and ROM preloaded with the StellarisWare Driver Library, Boot Loader, AES encryption lookup tables, and a cyclical redundancy check (CRC) function. The LM3S9997 also features real-time industrial connectivity, with a 10/100 Ethernet MAC/PHY, 2 CAN controllers, USB 2.0 Full Speed OTG/Host/Device, 2 SSI / SPI controllers, 2 I2C interfaces, an I2S interface, and 3 UARTs, as well as hardware-assisted support for synchronized industrial networks utilizing the IEEE 1588 Precision Time Protocol (PTP). The LM3S9997 microcontroller also features advanced motion control features, including 6 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 2 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 LM3S9997 microcontroller provides 16 digital comparators, a 24-bit systick timer, 4 32-bit or 8 16-bit general-purpose timers, 2 watchdog timers, 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.
