Description
The Stellaris LM3S101 microcontroller is based on the ARM Cortex™-M3 controller core operating at up to 20 MHz, with 8 kB flash and 2 kB SRAM. The LM3S101 also features real-time industrial connectivity, with an SSI / SPI controller, and a UART. Finally, the LM3S101 microcontroller provides a 24-bit systick timer, 2 32-bit or 4 16-bit general-purpose timers, a watchdog timer, a low drop-out voltage regulator so that only one supply voltage is required, brown-out reset, power-on reset controller, and up to 18 GPIOs.
- 32-bit ARM® Cortex™-M3 20-MHz processor core with System Timer (SysTick), integrated Nested Vectored Interrupt Controller (NVIC), and Thumb-2 instruction set
- Full-featured debug solution with debug access via JTAG and Serial Wire interfaces, and IEEE 1149.1-1990 compliant Test Access Port (TAP) controller
- 8 KB single-cycle flash and 2 KB single-cycle SRAM
- 2-18 GPIOs (depending on configuration) with programmable control for GPIO interrupts and pad configuration
- ARM FiRM-compliant Watchdog Timer ; plus two General-Purpose Timer Modules (GPTM), each of which provides two 16-bit timers/counters and can be configured to operate independently
- 10-bit Analog-to-Digital Converter (ADC) with analog input channels and a sample rate of samples/second
- Fully programmable 16C550-type UART
- Synchronous Serial Interface (SSI), supporting operation for Freescale SPI, MICROWIRE, or synchronous serial interfaces
- Two integrated analog comparators configurable for output to drive an output pin or generate an interrupt
- Industrial and extended temperature RoHS-compliant 28-pin SOIC, 48-pin LQFP and 48-pin QFN package (28-pin SOIC package is not recommended for new designs)
