Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TM4C123GH6PM | Same core, flash (256 KB), SRAM (32 KB), and package; lacks USB device PHY - requires external transceiver for USB functionality. | Not suitable for USB-native designs; appropriate where RS-232/RS-485 or Ethernet is primary interface. | Select when USB is unnecessary and cost reduction is prioritized over interface flexibility. |
| STM32F407VGT6 | ARM Cortex-M4F @ 168 MHz, 1 MB flash, 192 KB SRAM, no integrated USB PHY - uses external ULPI or full-speed PHY. | Better suited for high-throughput applications (e.g., audio streaming, image capture); lacks factory ROM bootloader for USB IAP. | Choose for higher clock speed and memory headroom, accepting added BOM complexity and firmware bring-up effort. |
Compared with TM4C123GH6PM, TM4C1236H6PMI7 provides integrated USB device capability and identical analog/peripheral feature set - eliminating external PHY components and simplifying certification.

FAQ
What is the maximum operating frequency of the TM4C1236H6PMI7?
The TM4C1236H6PMI7 operates at a maximum system clock frequency of 80 MHz, derived from its internal precision oscillator or external crystal source. This frequency is sustained across the full industrial temperature range (–40°C to +85°C) and supports deterministic real-time execution of control loops and communication stacks. The TM4C1236H6PMI7 achieves 2.5 DMIPS/MHz, delivering 200 DMIPS total performance for complex firmware tasks.
Does the TM4C1236H6PMI7 include a hardware floating-point unit?
Yes, the TM4C1236H6PMI7 integrates a single-precision IEEE 754-compliant floating-point unit (FPU) as part of its ARM Cortex-M4F core. This hardware accelerator enables efficient execution of trigonometric, exponential, and matrix operations required in motor control, sensor fusion, and digital power applications - eliminating software emulation delays. The TM4C1236H6PMI7 FPU is fully supported by TI's TivaWare™ C Series driver library and GCC/ARM compiler toolchains.
What USB capabilities does the TM4C1236H6PMI7 support?
The TM4C1236H6PMI7 supports USB 2.0 Full-Speed (12 Mbps) device-mode operation only, with an integrated on-die USB PHY and dedicated USB controller. It does not support USB host or OTG modes. The TM4C1236H6PMI7 implements standard USB classes including CDC (virtual COM port), HID, and MSC via TivaWare™ USB stack - enabling plug-and-play firmware updates, diagnostics, and data logging without external transceivers.
How much flash and SRAM memory does the TM4C1236H6PMI7 provide?
The TM4C1236H6PMI7 includes 256 KB of on-chip flash memory for program storage and 32 KB of SRAM for runtime data, stack, and heap allocation. Flash supports in-application programming (IAP) via the ROM bootloader, allowing field firmware updates over USB or UART. The TM4C1236H6PMI7 memory map is optimized for real-time responsiveness, with zero-wait-state access at 80 MHz for both memory types.
Is the TM4C1236H6PMI7 pin-compatible with other Tiva C Series microcontrollers?
The TM4C1236H6PMI7 shares the same 100-pin LQFP package and pinout with the TM4C123GH6PM and TM4C123BH6PM variants, enabling drop-in replacement where USB functionality is not required. However, pin compatibility does not guarantee functional equivalence - for example, TM4C123GH6PM lacks the integrated USB PHY present in the TM4C1236H6PMI7. Always verify peripheral mapping and electrical characteristics before substitution.
