The 2K x 8 EEPROM stores calibration constants and boot parameters without wearing the Flash. The 100-LQFP package (14x14 mm) provides 69 general-purpose I/O lines. Procurement teams should confirm last-time-buy windows and evaluate pin-compatible siblings in the Tiva C family for long-term production continuity.","metaTitle":"TM4C1231D5PZI Tiva C ARM Cortex-M4F MCU, 80MHz, 64KB Flash","metaDescription":"TM4C1231D5PZI Tiva C 32-bit ARM Cortex-M4F MCU, 80MHz speed, 64KB Flash, 24K x 8 RAM, 2K x 8 EEPROM, -40°C to 85°C, 100-LQFP.
