The 50 MHz Cortex-M3 core runs a lightweight TCP/IP stack and a control loop. ## Memory sizing for the application The Flash holds a full Ethernet stack plus application code; the RAM handles packet buffers and a modest data set. If your design needs more than 64 KB of working memory for large frame buffers or extensive look-up tables, you'll want to step up to a part with external memory interface — this one doesn't have one. ## Industrial temperature grade and peripherals The brown-out detect and POR ensure reliable startup in noisy industrial environments. The PWM and QEI peripherals are ready for motor control with quadrature encoder feedback. The watchdog timer is there for safety-critical loops — don't leave it disabled in production. The LM3S6965-EQC50-A2 is listed with an end-of-life (EOL) hot status. TI has transitioned the Stellaris line to the Tiva-C series.","metaTitle":"TI LM3S6965-EQC50-A2 ARM Cortex-M3 MCU, 50 MHz, 256 KB Flash","metaDescription":"Texas Instruments LM3S6965-EQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz core, 256 KB Flash, 64 KB RAM, Ethernet, -40 to 105°C.
