Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TM4C123GH6PM | Includes 2× CAN controllers and 1 MB/s UART oversampling; lacks hibernation module and VBAT support. | Better suited for automotive body control modules requiring CAN FD compatibility and higher UART baud rates. | Select TM4C123GH6PM when CAN interface is mandatory and ultra-low-power hibernation is not required. |
| STM32F407VGT6 | 168 MHz Cortex-M4F, 1 MB Flash, no integrated USB PHY; requires external USB transceiver and external RTC/battery backup. | Preferred for high-throughput data loggers needing larger code space and external SDRAM interface. | Choose STM32F407VGT6 only if design already includes external USB PHY and can accommodate added BOM cost and PCB area. |
Compared with TM4C123GH6PM and STM32F407VGT6, the TM4C1233H6PMIR offers unique integration of hibernation domain, USB PHY, and factory-trimmed internal oscillators - reducing bill-of-materials count and simplifying compliance testing for Class I industrial equipment.

FAQ
What is the operating temperature range of the TM4C1233H6PMIR?
The TM4C1233H6PMIR is rated for operation from -40°C to +105°C ambient temperature. This extended industrial temperature range ensures reliable functionality in harsh environments such as factory floor controllers, outdoor utility meters, and under-hood automotive modules. The device undergoes full characterization across this range for all key parameters including Flash programming voltage, ADC accuracy, and USB timing margins - making TM4C1233H6PMIR suitable for applications where thermal cycling and long-term stability are critical.
Does the TM4C1233H6PMIR include an integrated USB physical layer?
Yes, the TM4C1233H6PMIR integrates a full-speed USB 2.0 OTG physical layer with on-die termination resistors and ESD protection. This eliminates the need for external USB transceivers or discrete protection components in most designs. The USB module supports both host and device modes, and is fully compatible with TI's TivaWare™ USB stack for CDC, HID, and mass storage class implementations - significantly accelerating development of field-serviceable devices using TM4C1233H6PMIR.
How much SRAM and Flash memory does the TM4C1233H6PMIR provide?
The TM4C1233H6PMIR includes 32 KB of on-chip SRAM and 256 KB of single-cycle Flash memory. The SRAM is partitioned into general-purpose and hibernation-retentive sections, while the Flash supports read-while-write operation and has built-in error correction logic. These memory resources allow TM4C1233H6PMIR to run complex real-time tasks - such as multi-axis motion control with trajectory planning - while maintaining space for secure bootloaders and over-the-air update partitions.
Can the TM4C1233H6PMIR operate in ultra-low-power hibernation mode?
Yes, the TM4C1233H6PMIR features a dedicated hibernation module that reduces system current to 1.7 µA while retaining RTC time, 2 KB of battery-backed RAM, and wake-up capability via external pin or RTC alarm. This mode is enabled through VBAT supply and requires no external components. For battery-powered remote sensors or energy harvesters, TM4C1233H6PMIR's hibernation architecture provides deterministic wake-up latency (<5 µs) and eliminates the need for external RTC ICs - directly lowering system BOM cost and footprint.
What development tools are officially supported for the TM4C1233H6PMIR?
Texas Instruments officially supports the TM4C1233H6PMIR with Code Composer Studio™ IDE, TI's TivaWare™ C Series software suite, and the EK-TM4C123GXL LaunchPad™ development kit. These tools provide full debug visibility, pre-certified USB and TCP/IP stacks, and hardware abstraction layers for all peripherals. Engineers using TM4C1233H6PMIR benefit from TI's long-term toolchain commitment - including ongoing security patches, CMSIS-DSP library updates, and migration paths to newer Tiva and SimpleLink™ platforms.
