Description
The Stellaris® LM3S310 microcontroller is based on the ARM® Cortex-M3 controller core operating at up to 25 MHz, with 16 kB flash and 4 kB SRAM.The LM3S310 also features real-time industrial connectivity, with an SSI / SPI controller, and 2 UARTs.The LM3S310 microcontroller also features advanced motion control features, including 6 motion-control PWM outputs with dead-band and 1 fault protection inputs for low-latency shutdown.Finally, the LM3S310 microcontroller provides a 24-bit systick timer, 3 32-bit or 6 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 36 GPIOs.
32-bit ARM® Cortex™-M3 25-MHz processor core with System Timer (SysTick), integrated Nested Vectored Interrupt Controller (NVIC), Memory Protection Unit (MPU), 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
16 KB single-cycle flash and 4 KB single-cycle SRAM
3-36 GPIOs (depending on configuration) with programmable control for GPIO interrupts and pad configuration
ARM FiRM-compliant Watchdog Timer ; plus three 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) withanalog input channels and a sample rate ofsamples/second
Two fully programmable 16C550-type UARTs
Synchronous Serial Interface (SSI), supporting operation for Freescale SPI, MICROWIRE, or Texas Instruments synchronous serial interfaces
Three integrated analog comparators configurable for output to drive an output pin or generate an interrupt
Three PWM generator blocks, each with one 16-bit counter, two PWM comparators, a PWM signal generator, a dead-band generator, and an interrupt selector
Industrial and extended temperature RoHS-compliant 48-pin LQFP and 48-pin QFN package
