Integrates 96 KB Flash and 64 KB SRAM with an on-chip Ethernet MAC. ## Memory and peripheral budget for control applications 96 KB Flash and 64 KB RAM support a Modbus TCP stack with a few hundred registers and a PID loop. The 4-channel 10-bit ADC covers basic analog sensing. The 100-LQFP package (14x14 mm) provides 41 GPIOs. Listed as Active in the lifecycle record — no last-time-buy notice currently on file. For dual-sourcing planning, the Stellaris family shares pin-compatibility across density options in the same package, but no official cross-reference alternate is recorded for this exact order code.","metaTitle":"LM3S6537-IQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S6537-IQC50-A2 32-bit ARM Cortex-M3 MCU with 96 KB Flash, 64 KB RAM, Ethernet MAC, 50 MHz.
