Product Overview

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.
  • 32-bit ARM Cortex-M3 v7M architecture 50MHz operation
  • System timer, providing a simple, 24-bit clear-on-write, decrementing, wrap-on-zero counter
  • Thumb®-compatible Thumb-2-only instruction set processor core
  • Hardware-division and single-cycle-multiplication
  • Integrated nested vectored interrupt controller (NVIC)
  • 41 Interrupts with eight priority levels
  • Memory protection unit (MPU)
  • Unaligned data access, enabling data to be efficiently packed into memory
  • External non-maskable interrupt signal (NMI)
  • ARM Thumb2 mixed 16-/32-bit instruction set
  • Serial wire JTAG debug port (SWJ-DP)
  • Three sleep modes with clock gating for low power
  • IEEE 1149.1-1990 compatible test access port (TAP) controller
  • System power control using discrete external regulator
  • 32-bit Real-time clock (RTC)
  • ARM PrimeCell® 32-channel configurable µDMA controller
  • ARM FiRM-compliant watchdog timer
  • Two fully programmable 16C550-type UARTs with IrDA support
  • Synchronous serial interface (SSI) - master or slave operation
  • Two I2C modules - two transmission speeds standard (100Kbps) and fast (400Kbps)
