LM3S3Z26
The Stellaris® LM3S3Z26 microcontroller is based on the ARM® Cortex™-M3 controller core operating at up to 50 MHz, with 16 kB flash, 6 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 LM3S3Z26 also features real-time industrial connectivity, with USB 2.0 Full Speed Device, 2 SSI / SPI controllers, 2 I2C interfaces, and 3 UARTs. The microcontroller also features intelligent analog capability, including 2 analog comparators and 8 channels of highly accurate 10-bit analog-to-digital conversion - with the ability to sample at speeds of 1M samples per second. Finally, the LM3S3Z26 microcontroller provides 8 digital comparators, a 24-bit systick timer, 3 32-bit or 6 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 33 GPIOs.
