50 MHz Cortex-M3 with on-chip Ethernet MAC
The LM3S6537-IQC50-A2: 32-bit ARM Cortex-M3 MCU from the Stellaris 6000 series, clocked at 50 MHz. 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.
