It has 96 KB of Flash and 64 KB of RAM, with Ethernet, I2C, SPI, UART, IrDA, Microwire, and SSI interfaces. At 50 MHz, this Cortex-M3 handles moderate control loops, protocol stacks (TCP/IP, Modbus TCP), and data logging without breaking a sweat. It is not a high-throughput DSP replacement — the 10-bit ADC and lack of a hardware FPU or MAC tell you that. For a panel gateway or an Ethernet-enabled motor drive controller, though, the speed is well matched to the peripheral set. TI marked this part obsolete. No factory orders or last-time-buy window remain. The only channel is the independent surplus and broker market. The 108-ball BGA (10x10 mm) requires standard surface-mount reflow.","metaTitle":"LM3S6537-IBZ50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 96 KB Flash, Obsolete","metaDescription":"LM3S6537-IBZ50-A2 is an obsolete Stellaris ARM Cortex-M3 MCU with 50 MHz core, 96 KB Flash, 64 KB RAM, Ethernet, 41 I/O.
