Product details
Overview
TM4C123GH6PZT 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 ADC (up to 1MSPS), and dual CAN 2.0A/B controllers. It operates at 80 MHz, supports -40°C to +105°C industrial temperature range, and targets real-time embedded control in motor drives and industrial automation.
For engineers reviewing the TM4C123GH6PZT datasheet, TM4C123GH6PZT pinout, TM4C123GH6PZT application, or TM4C123GH6PZT equivalent, key selection criteria include its integrated USB PHY, hibernation module with RTC and battery-backed memory, deterministic interrupt latency under 10 cycles, and support for TivaWare™ C Series software stack.
Technical Context
The TM4C123GH6PZT integrates a single-core ARM Cortex-M4F CPU with hardware floating-point unit (FPU), enabling real-time signal processing and closed-loop control. Its memory subsystem includes 256 KB on-chip Flash with ECC protection, 32 KB SRAM, and 2 KB EEPROM - all accessible via tightly coupled bus architecture with zero-wait-state operation at 80 MHz.
Peripherals are managed through a unified clock gating and power control system. The microcontroller features four independent 32-bit general-purpose timers (with 64-bit concatenated mode), two 16-channel μDMA controllers, and a hibernation module supporting VBAT backup, RTC alarm wake-up, and deep-sleep current as low as 1.7 µA.

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 USB-active states; lacks hibernation module with RTC battery backup. | Select when higher clock speed and larger memory are critical, and USB is used only in host mode with external PHY. |
| MSP432P401RIPZT | ARM Cortex-M4F @ 48 MHz, 2 MB Flash, ultra-low-power design (80 nA hibernate), no CAN or USB OTG. | Superior energy efficiency for battery-only operation but lacks industrial connectivity (CAN/USB) and real-time PWM resolution. | Select for portable sensor nodes where CAN/USB are unnecessary and multi-year battery life is mandatory. |
Compared with STM32F407VGT6 and MSP432P401RIPZT, the TM4C123GH6PZT uniquely balances industrial connectivity (dual CAN + USB OTG), deterministic real-time control (sub-10-cycle interrupt latency), and low-power hibernation - making it optimal for cost-sensitive, field-deployed automation nodes requiring both performance and resilience.

FAQ
What is the maximum operating frequency of the TM4C123GH6PZT?
The TM4C123GH6PZT operates at a maximum system clock frequency of 80 MHz, derived from an internal PLL that accepts input from an external 4–25 MHz crystal or internal oscillator. This frequency is fully supported across the full industrial temperature range (-40°C to +105°C), and all peripherals-including USB, CAN, and ADC-are rated for concurrent operation at this speed. The TM4C123GH6PZT maintains timing compliance without derating in validated PCB layouts meeting TI's layout guidelines.
Does the TM4C123GH6PZT include an integrated USB physical layer?
Yes, the TM4C123GH6PZT integrates a full-speed USB 2.0 OTG physical layer (PHY) compliant with USB specification revision 2.0. It supports both host and device modes without requiring an external transceiver. The USB interface includes dedicated pins (USB0P/USB0M), internal termination resistors, and on-chip voltage regulators for VDDC-enabling direct connection to USB connectors with minimal external components.
How much hibernate-mode current does the TM4C123GH6PZT draw with RTC active?
The TM4C123GH6PZT draws 1.7 µA typical current in hibernate mode with the real-time clock (RTC) running and battery-backed RAM enabled. This measurement is specified at 3.0 V VBAT and 25°C, and remains below 5 µA across the full industrial temperature range. The hibernation module retains 2 KB of RAM, RTC time/date, and wake-up configuration while powered solely from VBAT.
What types of analog-to-digital conversion does the TM4C123GH6PZT support?
The TM4C123GH6PZT features a 12-bit successive-approximation ADC with up to 12 input channels, configurable sample rates up to 1 MSPS, and hardware-accelerated features including 4-level sample averaging, digital comparators, and temperature sensor input. It supports both single-ended and differential sampling modes, with dedicated sequencers allowing autonomous triggering from timers or GPIO edges-ideal for motor phase current sensing and power quality monitoring.
Is the TM4C123GH6PZT pin-compatible with other Tiva C Series microcontrollers?
No, the TM4C123GH6PZT is not pin-compatible with other Tiva C Series microcontrollers such as the TM4C1294NCPDT or TM4C1233H6PZ. While they share the same LQFP-100 package footprint, pin functions-including USB, CAN, and hibernation signals-are assigned to different physical pins. Migration requires PCB layout revision; however, firmware portability is high due to consistent TivaWare™ peripheral driver APIs and memory map alignment.
