Product Summary
The LM3S2739-IQC50-A2 microcontroller is based on the ARM controller core operating at up to 50 MHz, with 96 kB flash and 32 kB SRAM. The LM3S2739-IQC50-A2 also features real-time industrial connectivity, with a 10/100 Ethernet MAC/PHY, an SSI / SPI controller, an I2C interface, and 2 UARTs. The LM3S2739-IQC50-A2 microcontroller also features advanced motion control features, including 2 motion-control PWM outputs with dead-band and 1 fault protection inputs for low-latency shutdown. The microcontroller also features intelligent analog capability, including 2 analog comparators and 3 channels of highly accurate 10-bit analog-to-digital conversion - with the ability to sample at speeds of 250K samples per second.
