Overview
TM4C1233H6PGEI from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 80 MHz operation, 256 KB Flash, 32 KB SRAM, and integrated USB 2.0 OTG, PWM, ADC (12-bit, 1MSPS), and multiple serial interfaces (UART, SPI, I²C). It serves as a main system controller in industrial motor control, sensor gateway, and USB-connected embedded devices.
For engineers reviewing the TM4C1233H6PGEI datasheet, TM4C1233H6PGEI pinout, TM4C1233H6PGEI application, or TM4C1233H6PGEI equivalent, key selection criteria include its 80 MHz Cortex-M4F core with FPU, 100-pin LQFP package, -40°C to +105°C industrial temperature range, USB OTG support, and hibernation module for ultra-low-power wake-up capability.
Technical Context
The TM4C1233H6PGEI integrates a single-core ARM Cortex-M4F processor with hardware floating-point unit and memory protection unit (MPU), enabling deterministic real-time control with signal processing capability. It supports Thumb-2 instruction set, vector table relocation, and nested vectored interrupt controller (NVIC) with 8-level priority grouping.
Its system architecture includes a hibernation module with RTC, battery-backed memory, and VDD3ON mode for sub-μA sleep current; a μDMA controller supporting 32 channels with peripheral-to-memory and memory-to-memory transfers; and dual 12-bit ADCs with up to 1MSPS aggregate sampling rate across 16 input channels.

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 and peripherals, but 144-pin TQFP package with larger Flash (256 KB) and SRAM (32 KB); adds Ethernet MAC and CAN. | Suitable for networked PLCs or gateways requiring wired Ethernet or CAN bus connectivity - not needed for USB-only or isolated sensor nodes. | Select TM4C123GH6PM when Ethernet/CAN is required; TM4C1233H6PGEI is optimal for cost- and size-constrained USB-centric designs. |
| STM32F407VGT6 | ARM Cortex-M4F @ 168 MHz, 1 MB Flash, 192 KB SRAM, no native USB OTG PHY (requires external transceiver), different peripheral register map. | Better suited for compute-intensive applications (e.g., audio processing) but increases BOM and layout complexity due to external USB PHY requirement. | Choose STM32F407VGT6 only if higher clock speed or larger memory is mandatory; TM4C1233H6PGEI offers simpler USB integration and lower system-level cost. |
Compared with TM4C123GH6PM and STM32F407VGT6, the TM4C1233H6PGEI delivers optimal balance of USB integration, industrial temperature rating, and compact 100-pin LQFP packaging - reducing PCB area and eliminating external USB components while maintaining sufficient performance for sensor aggregation and motor control.

FAQ
What is the maximum operating frequency of the TM4C1233H6PGEI?
The TM4C1233H6PGEI operates at a maximum system clock frequency of 80 MHz, derived from its internal PLL driven by either the internal precision oscillator (±1% accuracy) or an external crystal. This frequency is fully supported across the entire industrial temperature range (-40°C to +105°C) and enables deterministic real-time execution for motor control and sensor processing tasks within the TM4C1233H6PGEI's specified electrical limits.
Does the TM4C1233H6PGEI include a built-in USB physical layer (PHY)?
Yes, the TM4C1233H6PGEI integrates a full-speed USB 2.0 OTG physical layer, eliminating the need for an external USB transceiver. It supports device, host, and OTG modes, and includes internal pull-up resistors on USB0DP for device enumeration. The TM4C1233H6PGEI's USB module complies with USB 2.0 specification and is validated for use with standard USB cables and hosts without additional PHY components.
What is the hibernation current consumption of the TM4C1233H6PGEI?
The TM4C1233H6PGEI achieves a typical hibernation current of 1.7 µA when the hibernation module is active, RTC is running, and 2 KB of battery-backed RAM is retained. This value is measured at 3.3 V and 25°C per TI's SPMS350E datasheet. The TM4C1233H6PGEI maintains this ultra-low power state while preserving critical context, enabling multi-year operation on coin-cell batteries in remote monitoring applications.
How many ADC channels does the TM4C1233H6PGEI support, and what is their resolution?
The TM4C1233H6PGEI features two independent 12-bit analog-to-digital converters (ADC0 and ADC1), each supporting up to 16 input channels via GPIO multiplexing. Each ADC achieves up to 1 MSPS aggregate sampling rate, with hardware averaging, digital comparators, and differential input capability. These specifications are confirmed in the TM4C1233H6PGEI's datasheet section 13 and apply directly to the exact part number without variant assumptions.
Is the TM4C1233H6PGEI pin-compatible with other Tiva C Series microcontrollers?
No, the TM4C1233H6PGEI is not pin-compatible with other Tiva C Series microcontrollers such as the TM4C123GH6PM or TM4C1294NCPDT. It uses a unique 100-pin LQFP (PGE) package with specific peripheral mappings; for example, USB0DP/DM are assigned to PD4/PD5, whereas other variants assign them to different pins. Board layout must be designed specifically for the TM4C1233H6PGEI footprint and signal routing.
