Product details
Overview
TM4C1233E6PZI7R 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, 12 channels), and 48 GPIOs in a 100-pin LQFP package. It serves as a main system controller in industrial HMI, motor control edge nodes, and low-power sensor gateways.
For engineers reviewing the TM4C1233E6PZI7R datasheet, TM4C1233E6PZI7R pinout, TM4C1233E6PZI7R application, or TM4C1233E6PZI7R equivalent, key selection criteria include its USB OTG capability, hibernation module with RTC and battery-backed memory, deterministic floating-point performance, and support for TivaWare™ software stack in real-time embedded designs.
Technical Context
The TM4C1233E6PZI7R implements a full-featured ARM Cortex-M4F core with single-precision FPU, NVIC with 80 interrupt lines, and memory protection unit (MPU). It integrates a hibernation module with dedicated 32.768 kHz RTC oscillator, battery-backed RAM, and wake-on-external-event capability.
Peripherals include four UARTs (one with ISO 7816 and SIR support), two I²C modules, two SPI controllers, two CAN 2.0A/B controllers, one USB 2.0 OTG controller, and a μDMA controller with 32-channel arbitration - all clocked from a programmable PLL with internal precision oscillator calibration.

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 vs. 256 KB), same core; adds Ethernet MAC and PHY, removes USB OTG | Better suited for wired industrial networking; lacks USB device capability required for field configuration | Select when Ethernet connectivity outweighs USB OTG needs and PCB layout accommodates larger 144-pin LQFP |
| STM32F407VGT6 | ARM Cortex-M4F @ 168 MHz, 1 MB Flash, no hibernate module, different peripheral set (no USB OTG PHY, no dedicated hibernate RTC) | Higher compute throughput but higher active power; requires external RTC and backup power circuitry for low-power timekeeping | Choose for compute-intensive tasks where USB OTG and sub-µA hibernate are not required |
Compared with TM4C123GH6PM and STM32F407VGT6, the TM4C1233E6PZI7R uniquely balances USB OTG integration, ultra-low-power hibernation with RTC, and industrial temperature tolerance in a compact 100-pin LQFP - making it optimal for space-constrained, battery-aware, field-configurable edge devices.

FAQ
What is the maximum operating frequency of the TM4C1233E6PZI7R?
The TM4C1233E6PZI7R operates at a maximum system clock frequency of 80 MHz, derived from its internal precision oscillator or external crystal via a programmable PLL. This frequency is fully supported across the industrial temperature range (–40°C to +105°C) and enables deterministic real-time execution of control algorithms and communication stacks within the TM4C1233E6PZI7R.
Does the TM4C1233E6PZI7R include an integrated USB physical layer?
Yes, the TM4C1233E6PZI7R integrates a full-speed USB 2.0 OTG physical layer (PHY) with on-die termination and 1 KB of dedicated endpoint FIFO memory. This eliminates the need for external USB transceivers and simplifies board design for applications requiring USB device, host, or OTG functionality - a key differentiator of the TM4C1233E6PZI7R versus many competing Cortex-M4 MCUs.
What low-power modes does the TM4C1233E6PZI7R support?
The TM4C1233E6PZI7R supports multiple low-power states including Sleep, Deep-Sleep, and Hibernate. Its dedicated hibernate module achieves 1.7 µA typical current draw while retaining RTC time, wake sources, and 256 bytes of battery-backed RAM - a capability confirmed in the official TM4C1233E6PZI7R datasheet and enabled by separate VBAT supply routing.
Is the TM4C1233E6PZI7R pin-compatible with other Tiva C Series microcontrollers?
No, the TM4C1233E6PZI7R is not pin-compatible with other Tiva C Series variants such as the TM4C123GH6PM (144-pin LQFP) or TM4C1294NCPDT (128-pin BGA). Its 100-pin LQFP footprint and specific peripheral mapping - including USB0VBUS/USB0ID placement and hibernate-specific pins - are unique to the TM4C1233E6PZ family and documented in the TM4C1233E6PZI7R datasheet.
What development tools are officially supported for the TM4C1233E6PZI7R?
Texas Instruments officially supports the TM4C1233E6PZI7R with the TivaWare™ Peripheral Driver Library, Code Composer Studio IDE, IAR Embedded Workbench, and Keil MDK-ARM. Evaluation is enabled via the TM4C123G LaunchPad (EK-TM4C123GXL), which shares the same core architecture and peripheral set - though users must verify pin mapping and voltage domain differences before direct code porting to the TM4C1233E6PZI7R.
