Program memory is 64 KB of on-chip Flash, backed by 8 KB of SRAM (8K x 8). The Flash is sufficient for a moderate firmware image with a RTOS kernel, while the SRAM handles stack, heap, and data buffers for UART or SPI transactions without external memory. 36 general-purpose I/O pins bring out the peripheral set: I²C, SPI, SSI, and UART/USART for sensor and actuator communication, plus a Quadrature Encoder Interface (QEI) for direct connection to incremental rotary encoders on motor shafts or linear slides. On-chip peripherals include brown-out detect, power-on reset, PWM, and a watchdog timer — the brown-out reset monitors the 3V–3.6V supply rail and holds the core in reset if the voltage dips below the threshold, preventing flash corruption during a power glitch.","metaTitle":"TI LM3S801-IGZ50-C2T ARM Cortex-M3 MCU, 50MHz, 64KB Flash","metaDescription":"Texas Instruments LM3S801-IGZ50-C2T 32-bit ARM Cortex-M3 MCU, 50MHz, 64KB Flash, 8KB SRAM, 36 I/O, -40°C to 85°C.
