Product details

The Texas Instruments LM3S1N11-IQC50-C5T is a 32-bit ARM Cortex-M3 MCU from the Stellaris 1000 series, clocked at 50 MHz with 64 KB of Flash program memory and 12 KB of SRAM.

The Cortex-M3 at 50 MHz handles PID loops and Modbus RTU framing. The DMA controller offloads UART or SPI data transfers.

Memory and connectivity — what the 64 KB Flash and 12 KB RAM support

64 KB of Flash supports a bootloader, a real-time kernel, and application code for a single-protocol device. 12 KB SRAM leaves room for UART buffers and a data array.
