The Texas Instruments LM3S601-EGZ50-C2T is a 32-bit ARM Cortex-M3 microcontroller from the Stellaris 600 series, clocked at 50 MHz. It carries 32 KB of Flash and 8 KB of SRAM, with 36 general-purpose I/O lines and a peripheral set that includes I²C, SPI, SSI, UART, a quadrature encoder interface (QEI), and PWM channels. The internal oscillator and brown-out detect, POR, and watchdog timer reduce external component count for compact embedded designs.
50 MHz Cortex-M3 — what it means for the control loop
At 50 MHz, the single-cycle multiply and hardware divide of the Cortex-M3 core handle sensor fusion, PID updates, and protocol framing (UART, SPI) without a dedicated co-processor. The 8 KB SRAM supports moderate data buffers — enough for a Modbus RTU slave or a simple motor-control state machine.
Lifecycle and sourcing
The LM3S601-EGZ50-C2T is listed as Active in production. It is sourced and quoted to order through independent distribution; availability and current pricing are confirmed at quote time against an RFQ.
