Frequently asked questions
What is TM4C1233E6PZIR's listed speed?
The TM4C1233E6PZIR runs at 80 MHz on a single ARM Cortex-M4F core with hardware floating-point unit.
What is the closest pin-compatible alternative to TM4C1233E6PZIR?
Texas Instruments does not list an official pin-compatible successor for the TM4C1233E6PZIR. For a drop-in replacement, review the Tiva C series TM4C123x family in the same 100-LQFP package — pin compatibility varies by exact memory and peripheral configuration. Submit an RFQ; we can cross-reference your BOM against available alternatives.
What compliance documentation does TI provide for TM4C1233E6PZIR?
Texas Instruments provides RoHS and REACH compliance data for the TM4C1233E6PZIR. UL and IEC certifications are not typically issued for individual ICs; the end-equipment certification depends on the full assembly. Request the TI material declaration sheet with your RFQ.
