It carries 30 GPIO lines and a 6-channel 10-bit ADC, all in a 48-LQFP (7x7 mm) package. ## Memory and I/O — sizing the BOM fit 64 KB Flash and 8 KB RAM place this MCU in the small-footprint control tier — enough for a single motor-control algorithm with a Modbus RTU stack, or for a sensor hub aggregating six 10-bit ADC channels over UART. The 30 GPIOs, combined with SPI, SSI, Microwire, and UART connectivity, cover most mixed-signal I/O needs without an external port expander. ## Sourcing reality — obsolete part, broker channel","metaTitle":"TI LM3S817-EQN50-C2T ARM Cortex-M3 MCU, 50 MHz, 64 KB Flash","metaDescription":"Texas Instruments LM3S817-EQN50-C2T Stellaris ARM Cortex-M3 MCU: 50 MHz core, 64 KB Flash, 8 KB RAM, 30 GPIO, 6-ch 10-bit ADC, -40 to 105°C, 48-LQFP.
