Product details

The 80 MHz core includes a single-precision floating-point unit, so PID loops and FFTs run without software emulation overhead. The 2K x 8 EEPROM stores calibration constants and failsafe parameters without wearing the Flash.

Industrial temperature range and connectivity — where this MCU fits

The 69 I/O pins and 22-channel 12-bit ADC let it read multiple sensors and drive indicators without external mux or GPIO expanders.

100-LQFP footprint and supply range — layout and power budget

Supply voltage spans 1.08V to 3.63V, so a single 3.3V rail works, and the part can also run from a 1.2V core supply if the application needs lower dynamic power.

That means no last-time-buy pressure and no forced redesign for the foreseeable future.

Frequently asked questions

What is the closest pin-compatible alternative to TM4C1233H6PZIR in the Tiva C family?

Within the Tiva C Series, the TM4C1233H6PZIR shares its 100-LQFP pinout and peripheral set with other TM4C123x parts that differ mainly in Flash and SRAM density. A direct alternative would be a TM4C123x variant with the same 100-LQFP footprint — the exact code depends on the required memory size. The base product number TM4C1233 identifies this specific Flash/RAM configuration.

What is the core speed and memory configuration of TM4C1233H6PZIR?

The TM4C1233H6PZIR runs an ARM Cortex-M4F core at 80 MHz. The 32-bit single-core architecture with FPU handles floating-point control loops in hardware.
