The 2.25 V to 2.75 V supply range and -40°C to 105°C rating suit it for outdoor telecom cabinets or engine-bay electronics where the ambient can swing hard. ## 128 KB Flash and 64 KB SRAM — sizing the firmware and data buffers The 128 KB Flash holds a moderate-size application stack — think a TCP/IP stack with a CANopen node and a few control loops. The 64 KB SRAM gives enough headroom for Ethernet packet buffers and a real-time data log without external memory. If your firmware needs more than that, you are looking at a larger Stellaris or a Cortex-M4 part; for a typical industrial node this pair is well matched.","metaTitle":"TI LM3S8730-EQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash","metaDescription":"Texas Instruments LM3S8730-EQC50-A2 Stellaris ARM Cortex-M3 MCU: 50 MHz, 128 KB Flash, 64 KB SRAM, Ethernet + CANbus, -40°C to 105°C, 100-LQFP.
