80 MHz Cortex-M4F with hardware floating-point
The Texas Instruments TM4C123FE6PMI7R is a 32-bit ARM Cortex-M4F MCU from the Tiva C series, clocked at 80 MHz with a single-cycle hardware FPU. 128 KB of Flash and 32 KB of RAM handle moderate firmware images; the 2 KB EEPROM saves configuration data without external storage. Supply runs from 1.08 V to 3.63 V on one rail.
Industrial temperature, 64-LQFP, and peripheral mix
The 64-LQFP package (10x10 mm) is a hand-solderable QFP; no hidden balls, no X-ray inspection needed. Peripheral set includes CAN, USB OTG, multiple UART/SPI/I²C, and a 12-channel 12-bit ADC.
Lifecycle status and sourcing
This part is flagged end-of-life (EOL hot). That means the manufacturer's last-time-buy window is closed or closing. No official successor is listed in the Tiva C family for this specific density and package, so if you need a pin-compatible drop-in, verify the footprint against the base TM4C123 series variants.
