Obsolete — sourcing through surplus channels
Texas Instruments has marked the LM3S2601-IQC50-A2 as obsolete.
Core specs and what they mean for a replacement search
Built around a 32-bit ARM Cortex-M3 core clocked at 50 MHz, the LM3S2601-IQC50-A2 carries 128 KB of on-chip flash and 32 KB of SRAM. The 100-LQFP package with a 14x14 mm body is a common footprint for mid-range MCUs — a direct pin-compatible replacement would need to match both the package and the 2.25 V to 2.75 V supply rail. A replacement candidate should carry the same temperature range if the original BOM called for it.
On-chip peripherals include brown-out detect, power-on reset, PWM, and a watchdog timer. The connectivity block supports CANbus, I2C, IrDA, Microwire, SPI, SSI, and UART/USART interfaces — a broad set that covers industrial fieldbus bridging, sensor communication, and serial debug links. With 60 general-purpose I/O lines and an internal oscillator, the part can run a modest control application without an external clock source, though the internal oscillator's accuracy may limit timing-critical CAN or UART baud-rate windows.
