Product details
Overview
TM4C1233E6PMI7 from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 80 MHz operation, 256 KB flash, 32 KB SRAM, integrated USB 2.0 OTG, 12-bit ADC (1 MSPS), and 32-channel μDMA - deployed in industrial motor control, sensor fusion gateways, and smart metering endpoints.
For engineers reviewing the TM4C1233E6PMI7 datasheet, TM4C1233E6PMI7 pinout, TM4C1233E6PMI7 application, or TM4C1233E6PMI7 equivalent, key selection criteria include USB host/device capability, hibernation mode current (1.7 µA), FPU-enabled floating-point math, and dual 16-bit general-purpose timers with PWM support.
Technical Context
The TM4C1233E6PMI7 integrates a single-core ARM Cortex-M4F CPU with hardware floating-point unit and memory protection unit (MPU), supporting Thumb-2 instruction set and vector table relocation. It implements a hierarchical clock tree with PLL-based system clock generation and multiple gated peripheral clocks.
Its analog subsystem includes two independent 12-bit ADCs (each with eight sample sequencers and hardware averaging), while digital peripherals feature four UARTs (one with ISO 7816/IR support), two I²C modules, three SPIs, and a USB 2.0 OTG controller with internal PHY and 1.25 KB endpoint RAM.
Key Specifications

|---|---|
| CPU Core | ARM Cortex-M4F @ 80 MHz - enables real-time deterministic control with single-cycle MAC and FPU for sensor signal processing. |
| Flash / SRAM | 256 KB flash + 32 KB SRAM - supports firmware updates via in-application programming and retains sufficient buffer space for USB packet handling. |
| ADC | Two 12-bit, 1 MSPS ADCs with 8 sequencers each - allows concurrent sampling of multiple analog sensors without CPU intervention. |
| USB Interface | USB 2.0 OTG with integrated PHY and 1.25 KB endpoint RAM - eliminates need for external transceiver and supports host/device/OTG roles in embedded applications. |
| Hibernate Current | 1.7 µA typical - enables battery-powered operation for >10 years in low-duty-cycle monitoring systems using RTC wake-up. |

Pinout & Package
TM4C1233E6PMI7 uses a 64-pin LQFP package (package code PM) with exposed thermal pad. Pin functions are defined per TI SPMS348E datasheet Rev E, Section 1.4 and Table 1-2 (Pin Assignments).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD / VDDA / VDDC | Power supply inputs | Separate domains for digital core (VDDC), analog (VDDA), and I/O (VDD) enable noise isolation critical for ADC accuracy. |
| PD0 / PD1 | UART0 TX/RX | Dedicated UART0 pins mapped to Port D - allow bootloader communication without GPIO remapping or peripheral conflict. |
| PA0 / PA1 | USB0 EPEN / USB0 PFLT | USB power enable and overcurrent fault detection - provide hardware-level USB port safety control independent of firmware. |
| PF0 / PF1 / PF2 / PF3 / PF4 | NMI / WAKE / USER SW / TCK / TMS | Multi-function pins supporting non-maskable interrupt, hibernate wake-up, user input, and JTAG debug interface - reduce BOM count in compact designs. |
| PC4 / PC5 / PC6 / PC7 | I²C0 SCL/SDA / I²C1 SCL/SDA | Dual I²C controllers with dedicated pins - permit simultaneous communication with multiple slave devices (e.g., EEPROM + temperature sensor + display driver). |
Key Features
| Feature | Design Value |
|---|---|
| Floating-Point Unit (FPU) | Hardware-accelerated IEEE 754 single-precision math - reduces FFT execution time by >90% vs software emulation in vibration analysis firmware. |
| Hibernation Module | RTC-backed wake-up from 1.7 µA state with battery-backed 256-byte RAM - preserves calibration data across power loss in portable test equipment. |
| μDMA Controller | 32-channel scatter-gather DMA - offloads ADC-to-memory transfers and UART buffering, freeing CPU for control loop execution. |
| Programmable Clock Gating | Per-peripheral clock enable/disable via RCGC registers - cuts dynamic power by up to 40% when unused peripherals (e.g., second I²C) are disabled. |
| GPIO Commit Registers | Write-once configuration lock for critical I/O pins - prevents accidental reconfiguration during runtime in safety-critical motor control sequences. |

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), added Ethernet MAC, no USB PHY - requires external PHY for USB. | Targeted at wired industrial networking where Ethernet is mandatory and USB is secondary. | Select TM4C123GH6PM only if Ethernet interface is required; TM4C1233E6PMI7 is preferred when USB device/host functionality is essential. |
| STM32F407VGT6 | Same Cortex-M4F core but 168 MHz max, 1 MB flash, no integrated USB PHY - needs external USB transceiver. | Better suited for high-throughput applications like audio streaming or complex GUIs requiring larger code space. | Choose STM32F407VGT6 when >256 KB flash or higher CPU frequency is needed; TM4C1233E6PMI7 offers lower BOM cost with integrated USB PHY. |
Compared with TM4C123GH6PM and STM32F407VGT6, the TM4C1233E6PMI7 uniquely combines USB 2.0 OTG with integrated PHY, hibernation current under 2 µA, and full TivaWare driver support - making it optimal for compact, battery-aware USB-connected edge devices.

FAQ
What is the maximum operating frequency of the TM4C1233E6PMI7?
The TM4C1233E6PMI7 operates at a maximum system clock frequency of 80 MHz, achieved via its on-chip PLL that accepts a 4–25 MHz crystal or external clock source. This frequency is fully supported across all operating temperature ranges (–40°C to +105°C) and voltage conditions (2.95–3.63 V), enabling deterministic real-time execution of control loops and communication stacks without derating.
Does the TM4C1233E6PMI7 include an integrated USB physical layer?
Yes, the TM4C1233E6PMI7 includes a full-speed USB 2.0 OTG controller with an integrated PHY, eliminating the need for an external transceiver. Its USB module supports device, host, and OTG modes, and provides 1.25 KB of dedicated endpoint RAM - confirmed in Section 14 of the SPMS348E datasheet and validated in TI's TivaWare USB library examples for TM4C1233E6PMI7.
What is the hibernation current specification for the TM4C1233E6PMI7?
The TM4C1233E6PMI7 achieves a typical hibernation current of 1.7 µA at 3.0 V and 25°C, as specified in Section 1.3.7 (Packaging and Temperature) and electrical characteristics Table 4-1 of the SPMS348E datasheet. This includes active RTC and 256 bytes of battery-backed RAM, making it suitable for decade-long battery operation in remote sensing nodes.
How many ADC modules does the TM4C1233E6PMI7 have, and what are their key capabilities?
The TM4C1233E6PMI7 integrates two independent 12-bit analog-to-digital converters (ADC0 and ADC1), each capable of 1 MSPS sampling. Each ADC supports eight configurable sample sequencers, hardware averaging (up to 64 samples), and differential input mode - features documented in Section 13 of the SPMS348E datasheet and used in TI's reference designs for precision sensor interfaces.
Is the TM4C1233E6PMI7 pin-compatible with other Tiva C Series microcontrollers?
No, the TM4C1233E6PMI7 is not pin-compatible with other Tiva C Series parts such as TM4C123GH6PM or TM4C1294NCPDT. While all use 64-pin LQFP packages, pin assignments differ significantly - for example, USB PHY pins (EPEN/PFLT) and hibernation control signals (HIB) are routed to unique locations. Migration requires PCB redesign, as confirmed by TI's package comparison tables in the TivaWare documentation.
