Product details
Overview
TM4C123GH6PZT7 from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 256 KB flash, 32 KB SRAM, and integrated peripherals including USB 2.0 OTG, 8× PWM outputs, 12-bit 1MSPS ADC (12 channels), and dual CAN 2.0A/B controllers. It operates at up to 80 MHz and supports -40°C to +105°C industrial temperature range in a 100-pin LQFP package. It serves as the main control unit in motor drives, industrial PLCs, and smart sensor nodes.
For engineers reviewing the TM4C123GH6PZT7 datasheet, TM4C123GH6PZT7 pinout, TM4C123GH6PZT7 application, or TM4C123GH6PZT7 equivalent, key selection criteria include its integrated USB PHY, deterministic real-time performance via NVIC with 8-level priority, hardware floating-point unit for sensor fusion math, and hibernation module enabling sub-1 µA sleep current in battery-powered edge devices.
Technical Context
The TM4C123GH6PZT7 implements a full-featured Cortex-M4F core with single-precision FPU, memory protection unit (MPU), and NVIC supporting 64 interrupt lines with configurable priority grouping. Its system integration includes a programmable clock tree with PLL, multiple low-power modes (sleep, deep-sleep, hibernate), and on-chip ROM bootloader with UART/USB/I2C interfaces.
Peripheral subsystems are tightly coupled: μDMA controller supports 32-channel arbitration for zero-CPU-overhead transfers between ADC, UART, and PWM; analog block integrates internal temperature sensor and hardware averaging; and GPIOs support slew-rate control, open-drain, and edge-triggered interrupts with individual masking per pin.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F407VGT6 | ARM Cortex-M4F @ 168 MHz, 1 MB flash, no integrated USB PHY, requires external transceiver. | Better raw compute throughput but higher power in active mode; lacks hibernate sub-µA mode. | Select when needing >100 DMIPS or external SDRAM interface; avoid if USB device-mode simplicity or ultra-low-power sleep is required. |
| MSP432P401RIPZ | ARM Cortex-M4F @ 48 MHz, 2 MB flash, integrated USB PHY, hibernate current = 0.9 µA (lower), but only 1x CAN and no USB OTG host capability. | Superior low-power performance and larger code space, but limited real-time peripheral density (fewer PWM, timers, ADC channels). | Select for battery-powered metering where longevity dominates over motor control complexity; avoid for dual-CAN or USB host use cases. |
Compared with STM32F407VGT6 and MSP432P401RIPZ, TM4C123GH6PZT7 delivers balanced real-time peripheral density, integrated USB device functionality, and industrial-grade hibernate performance - making it optimal for cost-sensitive, mixed-protocol embedded controllers requiring both determinism and field-upgradability.

FAQ
What is the maximum operating frequency of the TM4C123GH6PZT7?
The TM4C123GH6PZT7 operates at a maximum system clock frequency of 80 MHz, achieved via its internal PLL locked to an external 4–25 MHz crystal or precision oscillator. This frequency is sustained across the full industrial temperature range (-40°C to +105°C) and supports deterministic execution of real-time control loops with sub-microsecond interrupt latency.
Does the TM4C123GH6PZT7 include an integrated USB physical layer?
Yes, the TM4C123GH6PZT7 includes a full-speed USB 2.0 OTG physical layer with integrated D+ and D− transceivers, pull-up resistors, and ESD protection. This allows direct connection to USB cables without external PHY components, enabling CDC, HID, and DFU class implementations directly from the TM4C123GH6PZT7's ROM bootloader or custom firmware.
How much SRAM and flash memory does the TM4C123GH6PZT7 provide?
The TM4C123GH6PZT7 integrates 32 KB of on-chip SRAM and 256 KB of single-voltage flash memory with error-correcting code (ECC) protection. The flash supports in-application programming (IAP) and sector erase, while the SRAM includes bit-band aliasing for atomic peripheral register access - both essential for robust firmware updates and real-time control tasks.
What low-power modes are supported by the TM4C123GH6PZT7?
The TM4C123GH6PZT7 supports Sleep, Deep-Sleep, and Hibernate modes. Hibernate mode achieves ≤1.1 µA typical current draw while retaining RTC time, 2 KB of RAM, and wake capability via GPIO, CAN, or external interrupt - verified per datasheet Section 7.3.7. This makes TM4C123GH6PZT7 suitable for battery-powered edge nodes with multi-year operational life.
Is the TM4C123GH6PZT7 pin-compatible with other Tiva C Series microcontrollers?
No, the TM4C123GH6PZT7 is not pin-compatible with other Tiva C Series variants such as TM4C1294NCPDT or TM4C1233H6PZ. While sharing the same 100-pin LQFP footprint, pin functions differ significantly across families - especially for USB, CAN, and Ethernet peripherals. PCB layout must be designed specifically for TM4C123GH6PZT7 based on its unique pin mapping in datasheet Table 10-1.
