Product details

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.

Industrial temperature grade and supply range

Rated for -40 to 85 °C operation. Supply voltage is 2.25 V to 2.75 V. The 100-LQFP package (14x14 mm) provides 41 GPIOs.

Sourcing and lifecycle

Listed as Active in the lifecycle record — no last-time-buy notice currently on file. This part is sourced through independent distribution and quoted to order against an RFQ. Availability and current pricing are confirmed at quote time. 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.

Frequently asked questions

What is the closest pin-compatible alternative to LM3S6537-IQC50-A2?

Within the Stellaris 6000 series, higher-density siblings in the same 100-LQFP package are pin-compatible, but no official second-source alternate is documented for this specific order code.

What is the core speed of LM3S6537-IQC50-A2?

The ARM Cortex-M3 core runs at 50 MHz.
