The floating-point unit handles PID loops and sensor fusion math without a separate DSP coprocessor. 105 general-purpose I/O lines in the 144-LQFP package give enough pins to drive a parallel LCD, read a bank of encoders, and still leave room for a CAN transceiver and two UARTs. ## Industrial temperature grade and on-chip peripherals","metaTitle":"Texas Instruments TM4C1231H6PGEI7R Tiva C MCU, 80MHz ARM Cortex-M4F","metaDescription":"TM4C1231H6PGEI7R Tiva C series ARM Cortex-M4F MCU, 80MHz, 256KB Flash, 32K x 8 SRAM, 105 I/O, 144-LQFP, -40°C to 85°C.

For a drop-in replacement with the same package and I/O count, look at the TM4C123GH6PMI7R — it offers the same 80 MHz Cortex-M4F core, 256 KB Flash, and 32K x 8 SRAM, but with additional USB OTG connectivity. Verify the peripheral set against your firmware before swapping."},{"question":"What is TM4C1231H6PGEI7R's listed speed (80 MHz) on this component line?","answer":"The core runs at 80 MHz, which is the maximum clock for the Tiva C series Cortex-M4F. This provides enough throughput for real-time control loops and sensor fusion without external clock multiplication."},{"question":"What compliance documentation does this brand provide for TM4C1231H6PGEI7R (RoHS, REACH, UL, IEC)?","answer":"Texas Instruments provides RoHS and REACH compliance declarations for this part. The 144-LQFP package is lead-free and RoHS-compliant per TI's standard material declaration. UL and IEC certifications are not listed for this component; consult the TI compliance portal for the latest documentation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TM4C1231H6PGEI7R","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TM4C1231H6PGEI7R when reusing this data.
