The LM3S3748-IQC50-A0 is a Stellaris? 32-bit Microcontroller based on the ARM Cortex-M3 RISC architecture core. The device offers efficient performance and extensive integration, favourably positioning the device into applications requiring significant control-processing and connectivity capabilities. The Stellaris LM3S3000 series provides the industry's first ARM Cortex-M3 microcontrollers with USB 2.0 full-speed on-the-go/host/device combinations. For applications requiring extreme conservation of power, the device features a battery-backed hibernation module to efficiently power down the LM3S3748 to a low-power state during extended periods of inactivity. With a power-up/power-down sequencer, a continuous time counter (RTC), a pair of match registers, an APB interface to the system bus and dedicated non-volatile memory, the hibernation module positions the LM3S3748 microcontroller perfectly for battery applications.
