Buyers should evaluate long-term supply risk and consider qualifying a second source or a newer Cortex-M3/M4 family member for future builds. ## 50 MHz Cortex-M3 — enough for a CAN gateway or motor control loop At 50 MHz the ARM Cortex-M3 core delivers about 1.25 DMIPS/MHz, giving roughly 62.5 DMIPS — sufficient for real-time control tasks like a CANopen master node, a brushless DC motor FOC loop, or a multi-sensor data concentrator. The 8-channel 10-bit ADC at 1 Msps (typical) handles analog feedback for current sensing or temperature monitoring. ## Package and supply rails — layout notes Decouple with 100 nF per VDD pin plus a bulk 10 µF ceramic near the supply entry. The 52 GPIOs are 5 V-tolerant on most pins per the Stellaris family datasheet (not confirmed in this specific variant's evidence, but typical).","metaTitle":"LM3S2948-EQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz, NRND","metaDescription":"Texas Instruments LM3S2948-EQC50-A2 Stellaris ARM Cortex-M3 MCU: 50 MHz, 256 KB Flash, 64 KB SRAM, CANbus, -40°C to 105°C.
