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, RAM, and peripherals - differs only in packaging (100-pin LQFP vs. 64-pin LQFP) and temperature range (–40°C to +105°C). | Higher ambient operating temperature required; fewer GPIOs and no USB HS support. | Select TM4C123GH6PM only when extended temperature range is mandatory and USB Host/OTG functionality is unused. |
| STM32F407VGT6 | ARM Cortex-M4F @ 168 MHz, 1 MB flash, 192 KB RAM, no integrated USB PHY - requires external USB transceiver for device mode. | Higher CPU throughput but larger footprint and added BOM complexity for USB connectivity. | Choose STM32F407VGT6 when raw compute performance outweighs integration benefits and board space allows external USB PHY. |
Compared with TM4C1230H6PMI7, TM4C123GH6PM offers extended temperature tolerance at the cost of reduced I/O count and USB capability, while STM32F407VGT6 delivers higher clock speed and memory but increases design complexity for USB-enabled applications due to external PHY dependency.

FAQ
What is the maximum operating frequency of the TM4C1230H6PMI7?
The TM4C1230H6PMI7 operates at a maximum system clock frequency of 80 MHz, achieved via its internal PLL configured from the main oscillator or external crystal. This frequency applies to both the Cortex-M4F core and most peripherals, with certain modules (e.g., USB) requiring specific clock domain settings. The TM4C1230H6PMI7 maintains timing compliance across its full industrial temperature range (-40°C to +85°C) at this speed.
Does the TM4C1230H6PMI7 include an integrated USB physical layer (PHY)?
Yes, the TM4C1230H6PMI7 integrates a full-speed USB 2.0 PHY compliant with USB specification revision 2.0. It supports Device, Host, and OTG modes without requiring external transceivers. Key pins - USB0VBUS, USB0ID, USB0DM, and USB0DP - are dedicated and electrically characterized for direct connection to USB connectors, simplifying layout and reducing bill-of-materials cost.
How much flash and SRAM memory does the TM4C1230H6PMI7 provide?
The TM4C1230H6PMI7 includes 256 KB of on-chip flash memory with error-correcting code (ECC) and 32 KB of general-purpose SRAM. Flash supports dual-bank operation for safe firmware updates, while SRAM is partitioned into contiguous blocks accessible by CPU and μDMA. Both memories are directly mapped in the Cortex-M4F address space and retain data across sleep modes.
What analog peripherals are integrated into the TM4C1230H6PMI7?
The TM4C1230H6PMI7 integrates a 12-bit successive-approximation register (SAR) ADC with up to 12 input channels and 1 MSPS sampling rate, two analog comparators with programmable hysteresis, and an internal temperature sensor calibrated across temperature. All analog blocks share dedicated VDDA/GNDA rails and support hardware oversampling for improved effective resolution - critical for precision sensor interfacing.
Is the TM4C1230H6PMI7 supported by Texas Instruments' official software tools?
Yes, the TM4C1230H6PMI7 is fully supported by TI's TivaWare™ Peripheral Driver Library, Code Composer Studio™ IDE, and TI's Uniflash programming tool.
