Key Features
- 32-bit ARM Cortex-M4F core with hardware floating-point unit (FPU) enabling efficient DSP and control algorithm execution at up to 25 MHz
- 128 KB Flash and 32 KB SRAM with DMA controller for high-throughput peripheral data transfers in industrial control and sensor fusion applications
- 64-pin LQFP package with JTAG boundary scan support, ADC, and a rich peripheral set simplifying board-level test and mixed-signal embedded designs
Applications
The TM4C1236E6PMIR is suited for industrial control panels, motor drive systems, and precision measurement instruments that require floating-point computation for PID or DSP algorithms within a compact 64-pin LQFP footprint. Its 128 KB Flash provides ample room for communication stacks such as USB, CAN, or Ethernet alongside application firmware, while the DMA controller offloads ADC sampling and UART data transfers from the CPU. The device is also used in embedded motor control applications where the Cortex-M4F FPU accelerates sine/cosine calculations needed for field-oriented control algorithms.

Frequently Asked Questions
What core architecture and maximum clock frequency does TM4C1236E6PMIR offer for embedded control?
The TM4C1236E6PMIR is based on a 32-bit ARM Cortex-M4F core running at up to 25 MHz, with a single-precision hardware FPU that accelerates floating-point operations by up to 10× compared to software emulation, making it efficient for PID controllers and trigonometric calculations in motor drives.
How much non-volatile and volatile memory does TM4C1236E6PMIR integrate?
The device includes 128 KB of internal Flash for program storage and 32 KB of SRAM for runtime data, providing sufficient memory for a full USB or CAN communication stack alongside an application layer in systems that do not require external memory expansion.
What debugging and boundary scan capabilities does TM4C1236E6PMIR support for production testing?
The TM4C1236E6PMIR supports JTAG boundary scan per IEEE 1149.1, enabling automated PCB-level interconnect testing in production environments. The JTAG interface also provides CoreSight debug access for single-step debugging and hardware breakpoints using standard tools such as Code Composer Studio and IAR Embedded Workbench.
In which scenarios is TM4C1236E6PMIR preferred over a lower-cost Cortex-M0 device for embedded sensing?
When the application involves floating-point PID loops, FFT-based vibration analysis, or 3-phase motor FOC — all requiring frequent single-precision multiply-accumulate operations at 25 MHz — the Cortex-M4F FPU of TM4C1236E6PMIR executes these up to 10× faster than a software float library on a Cortex-M0, reducing latency in control loops that must complete within 50 µs cycle times.
