The 50 MHz core delivers enough throughput for real-time control loops and moderate protocol stacks. The Ethernet MAC can handle TCP/IP offload without a separate controller, but the 64 KB RAM limits buffer depth — expect to tune stack memory for smaller packet windows. This part is marked obsolete by the manufacturer. No official successor is listed. For BOM lines that require this exact order code, sourcing moves to the independent channel. ## Connectivity and peripheral set Ethernet, I²C, SPI, SSI, UART, and IrDA are on-chip. The 41 GPIOs are multiplexed with these peripherals. The internal oscillator saves an external crystal for non-critical timing.","metaTitle":"LM3S6537-EQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 96 KB Flash","metaDescription":"Obsolete LM3S6537-EQC50-A2 32-bit MCU with 50 MHz Cortex-M3 core, 96 KB Flash, 64 KB RAM, Ethernet, industrial temp.
