The 128 KB Flash and 64 KB SRAM give it room for a moderate firmware stack with a CANopen or custom protocol layer, plus a few kilobytes of buffered sensor data. ## Industrial temperature and connectivity Rated from -40°C to 105°C, the LM3S2730-EQC50-A2T operates on a 2.25 V to 2.75 V supply. The internal oscillator saves an external crystal.","metaTitle":"LM3S2730-EQC50-A2T Stellaris ARM Cortex-M3 MCU, 50MHz, 128KB Flash, 64KB SRAM","metaDescription":"Obsolete LM3S2730-EQC50-A2T ARM Cortex-M3 MCU from TI Stellaris series. 50MHz, 128KB Flash, 64KB SRAM, CANbus, 60 I/O, 100-LQFP, -40°C to 105°C.
