The 64 KB RAM is split between code data and the 60 I/O bit-banding region; if you plan to buffer large CAN message queues or run a TCP/IP stack over an external PHY, watch the heap margin. The part has no external memory interface — everything stays on-chip.","metaTitle":"LM3S2730-IQC50-A2T Stellaris Cortex-M3 MCU, 50 MHz, 128 KB Flash","metaDescription":"TI Stellaris LM3S2730-IQC50-A2T ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash, 64 KB RAM, 60 I/O, -40 to 85 °C, 100-LQFP.
