The LM3S6611-IQC50-A2: The Texas Instruments LM3S6611 is a 32-bit ARM Cortex-M3 MCU from the Stellaris 6000 series, clocked at 50 MHz with 128 KB of Flash program memory and 32 K x 8 of SRAM. It integrates an Ethernet MAC and PHY alongside I²C, SPI, SSI, UART, IrDA, and Microwire serial interfaces, plus 46 general-purpose I/O lines.
This part is marked obsolete. For existing BOM lines, procurement will need to source through surplus or independent-distributor channels.
No official replacement order code is listed in the lifecycle record. For a pin-compatible alternative within the Stellaris family, a cross-reference search against other LM3S6611 variants or a migration to the Tiva-C TM4C series may be considered, but no direct drop-in is confirmed.
The core processor runs at 50 MHz.
It belongs to the Stellaris ARM Cortex-M3S 6000 series.
