LM3S613-EQN50-C2

TEXAS INSTRUMENTS LM3S613-EQN50-C2 32Bit Microcontroller, ARM Cortex-M3, 50MHz, 32KB, 8KB, 48Pins, QFN

The is a Stellaris® 32-bit Microcontroller based on the ARM Cortex-M3 RISC core operating at up to 50MHz, with 32kB flash and 8kB SRAM. The device features real-time industrial connectivity, with an SSI/SPI controller, an I2C interface and 2 UARTs. The device also features advanced motion control features, including 4 motion-control PWM outputs with dead-band and 1 fault protection inputs for low-latency shutdown. The microcontroller also features intelligent analog capability, including 1 analog comparators and 4 channels of highly accurate 10-bit analog-to-digital conversion - with the ability to sample at speeds of 500K samples per second. The LM3S613 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 32 GPIOs.
