The TM4C1233E6PMI7 is a Tiva C series 32-bit MCU built around an ARM Cortex-M4F core clocked at 80 MHz. The floating-point unit on this core handles single-cycle multiply-accumulate and divide operations natively, which means sensor fusion algorithms, PID loops with fractional gains, and FFT-based diagnostics run without software emulation or external DSP. That 80 MHz is the timing closure boundary for a 12-bit ADC sample-and-convert sequence or a CAN message assembly — budget your interrupt latency and context-switch overhead accordingly.
Memory map and peripheral set for a BOM-fit decision
On-chip memory totals 128 KB of Flash for program storage, 32 KB of SRAM for runtime data, and 2 KB of EEPROM for calibration constants or boot parameters that survive a power cycle. The 12-bit ADC with 12 channels covers multi-sensor acquisition without an external converter.
The 64-LQFP package provides 43 I/O. Supply range is 1.08 V to 3.63 V.
Lifecycle reality — EOL hot, last-time-buy window
The TM4C1233E6PMI7 is flagged as EOL hot, meaning the manufacturer's last-time-buy period is active or imminent. For a BOM line in production, this is the signal to secure a lifetime buy quantity or begin qualification of a pin-compatible migration path. No official successor order code has been posted for this specific variant, so the replacement path is either a later Tiva C die revision or a cross-family Cortex-M4F from TI's portfolio.
