At this speed, a PID update or CAN message handling completes in a few microseconds — fast enough for servo drives and industrial PLCs. The 64 KB SRAM gives you room for a modest RTOS heap and several frame buffers for the QEI or ADC data. The 256 KB Flash holds a full firmware image with room for a bootloader and a configuration table. ## Peripheral set for motor control and industrial networking The LM3S2965 includes a CAN 2.0B controller for industrial fieldbus, a quadrature encoder interface for reading motor shaft position, and PWM timers with dead-band generation for driving H-bridges. The 4-channel 10-bit ADC samples at rates suitable for current sensing in a motor phase loop. Brown-out detection and POR keep the system from running on a glitchy supply rail. The 100-LQFP (14x14 mm body) is a hand-solderable, inspectable package — no X-ray needed for rework.","metaTitle":"LM3S2965-IQC50-A2T Stellaris ARM Cortex-M3 MCU, 50MHz, NRND","metaDescription":"Texas Instruments Stellaris LM3S2965-IQC50-A2T ARM Cortex-M3 MCU, 50MHz, 256KB Flash, 64KB RAM, -40 to 85°C, 100-LQFP.
