The 100-LQFP package provides 67 GPIOs and a 16-channel 10-bit ADC. This part was designed for industrial control, automotive gateway, and human-machine interface applications where the Cortex-M3 core and connectivity mix reduce external component count. The LM3S5651-IQC80-C5 is officially obsolete (EOL). No new production is planned. No direct pin-compatible replacement is listed; a design migration to a current Stellaris or Tiva-C family part would require a board respin and firmware port.","metaTitle":"LM3S5651-IQC80-C5 Stellaris ARM Cortex-M3 MCU, 80 MHz, 128 KB Flash","metaDescription":"Texas Instruments LM3S5651-IQC80-C5 32-bit ARM Cortex-M3 MCU, 80 MHz, 128 KB Flash, 32K x 8 RAM, 100-LQFP.
