On-chip memory is 32 KB of flash and 8 KB of SRAM. The flash holds the application plus a bootloader; the SRAM covers the stack, heap, and a few frame buffers. For a UART-to-SPI gateway or a brushless-DC controller, that is enough headroom. If the firmware image pushes past 28 KB, you will need to look up the family for a larger flash variant. ## Industrial temperature grade and peripheral set Connectivity includes I²C, SPI, SSI, UART/USART, Microwire, and a quadrature encoder interface (QEI). That QEI block is the reason this part shows up in servo drive and conveyor feedback designs — it decodes the A/B/I signals from an incremental encoder without bit-banging GPIOs. The 36 GPIOs leave room for a parallel LCD or a keypad matrix alongside the serial buses. On-chip peripherals include brown-out detect, POR, PWM, and a watchdog timer. The internal oscillator means you can bring up the UART without an external crystal, though the accuracy is good enough for asynchronous serial, not for a CAN node without a resonator. Housed in a 48-VFQFN with an exposed pad (7x7 mm body). Without that, the junction temperature rises 20-30°C above the ambient under continuous 50 MHz operation. Surface-mount only; the VQFN package is not hand-solderable without a hot-air station and a stencil. For prototyping, a QFN breakout board with the correct pad pattern is the practical route.","metaTitle":"TI LM3S601-EGZ50-C2 Cortex-M3 MCU, 50 MHz, 32 KB Flash","metaDescription":"Texas Instruments LM3S601-EGZ50-C2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 32 KB flash, 8 KB RAM, -40 to 105°C, 48-VQFN.
