At 50 MHz, this Cortex-M3 delivers enough throughput for a single Modbus RTU master plus a PID loop running at a few kilohertz. The 16 KB RAM is tight for a full TCP/IP stack but comfortable for a bare-metal state machine or a small RTOS with a few tasks. If your firmware needs room for a larger heap or multiple protocol buffers, the 64 KB Flash fills up before the RAM does — watch your linker map. The 100-LQFP package (14x14 mm) needs a standard reflow profile; the fine pitch means a clean solder paste stencil is non-negotiable.","metaTitle":"TI LM3S1165-IQC50-A2 ARM Cortex-M3 MCU, 50MHz, 64KB Flash, 100-LQFP","metaDescription":"Texas Instruments LM3S1165-IQC50-A2 Stellaris ARM Cortex-M3 MCU, 50MHz, 64KB Flash, 16KB RAM, 43 I/O, 100-LQFP, -40°C to 85°C.
