Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TM4C123GH6PM | Higher flash (256 KB → 256 KB same), but adds Ethernet MAC and more GPIOs (69 vs 61); larger LQFP-144 package. | Required when Ethernet connectivity or additional I/O count is needed; not drop-in due to different pinout and package. | Select TM4C123GH6PM only if Ethernet or expanded I/O is mandatory; otherwise TM4C1233E6PZIR offers optimal BOM and layout simplicity. |
| STM32F401CEU6 | ARM Cortex-M4F @ 84 MHz, 512 KB flash, 96 KB SRAM, no integrated USB PHY - requires external transceiver. | Better suited for high-code-footprint applications needing extended RAM; lacks hibernation module and battery-backed RTC. | Choose STM32F401CEU6 for memory-intensive tasks where USB is optional; TM4C1233E6PZIR remains superior for USB-native, ultra-low-power designs. |
Compared with TM4C123GH6PM and STM32F401CEU6, the TM4C1233E6PZIR uniquely balances USB integration, hibernation efficiency, and compact LQFP-100 packaging - making it optimal for space-constrained, battery-aware industrial edge nodes requiring certified USB device functionality.

FAQ
What is the maximum operating frequency of the TM4C1233E6PZIR?
The TM4C1233E6PZIR operates at a maximum system clock frequency of 80 MHz, derived from its internal PLL locked to an external 4–25 MHz crystal or oscillator. This frequency is sustained across the full industrial temperature range (–40°C to +105°C) and supports deterministic real-time execution of control loops and communication stacks.
Does the TM4C1233E6PZIR include an integrated USB physical layer?
Yes, the TM4C1233E6PZIR integrates a full-speed USB 2.0 physical layer (PHY) compliant with USB specification revision 2.0. This eliminates the need for an external transceiver and supports standard USB device classes including CDC, HID, and MSC directly from the MCU pins USB0DP and USB0DM.
What low-power modes does the TM4C1233E6PZIR support, and what is the lowest current draw?
The TM4C1233E6PZIR supports Sleep, Deep-Sleep, and Hibernation modes. In Hibernation mode with RTC enabled and battery-backed RAM active, typical current consumption is 2.5 µA - verified per TI's SPMS349E datasheet under VDD = 3.3 V and TA = 25°C.
Is the TM4C1233E6PZIR pin-compatible with other Tiva C Series MCUs like the TM4C123GH6PM?
No, the TM4C1233E6PZIR is not pin-compatible with the TM4C123GH6PM. While both use LQFP packages, the TM4C1233E6PZIR uses LQFP-100 whereas the TM4C123GH6PM uses LQFP-144, and their pin assignments differ significantly - especially for USB, Ethernet, and additional peripherals.
What development tools and software support are available for the TM4C1233E6PZIR?
Texas Instruments provides TivaWare™ Peripheral Driver Library, Code Composer Studio™ IDE, and TI-RTOS kernel support for the TM4C1233E6PZIR. Hardware evaluation is supported via the EK-TM4C123GXL LaunchPad, which shares the same core architecture and peripheral set for rapid prototyping and validation.
