The 49 I/O lines in a 64-LQFP package keep board routing manageable for a 4-layer design. ## Lifecycle reality — EOL hot, sourced through independent channels This part is flagged EOL hot, meaning Texas Instruments has issued an end-of-life notice. The official status is active, but the EOL hot flag tells procurement to treat it as a last-time-buy candidate.","metaTitle":"Texas Instruments TM4C1232H6PMIR Tiva C MCU, 80 MHz","metaDescription":"TM4C1232H6PMIR 32-bit ARM Cortex-M4F MCU, 80 MHz, 256 KB Flash, 32K x 8 RAM, CAN, USB, -40°C to 85°C, 64-LQFP.

The TM4C123GH6PM is a pin-compatible alternative in the same 64-LQFP package with the same core and memory, adding USB OTG. Verify USB pin allocation before substituting."},{"question":"Is TM4C1232H6PMIR compatible with TivaWare?","answer":"Yes — this part is part of the Tiva C series and is supported by TI's TivaWare software library, including peripheral driver libraries and the USB stack."},{"question":"What is the pinout for TM4C1232H6PMIR?","answer":"The pinout follows the standard 64-LQFP Tiva C mapping.
