The 25 MHz Cortex-M3 core delivers roughly 25 DMIPS, enough to handle a Modbus TCP stack, a PID loop, and local I/O scanning in a single cycle. For applications that need faster protocol parsing or tighter loop times — say, a multi-axis stepper controller — a higher-speed sibling in the Stellaris family would be the correct fit. At this clock rate, the part sits comfortably in the mid-range of the Cortex-M3 performance band, trading throughput for lower dynamic power draw on a 2.25 V to 2.75 V supply. Texas Instruments has marked the LM3S6100 as obsolete.","metaTitle":"LM3S6100-IBZ25-A2 Stellaris ARM Cortex-M3 MCU, 25MHz, 64KB Flash","metaDescription":"Texas Instruments LM3S6100-IBZ25-A2 Stellaris ARM Cortex-M3 MCU, 25MHz, 64KB Flash, 16K x 8 RAM, Ethernet, -40 to 85°C, 108-BGA.
