Product details
Overview
TM4C123GE6PZI from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 80 MHz operation, 256 KB flash, 32 KB SRAM, integrated USB 2.0 device/host/OTG controller, 12-bit ADC (1 MSPS, 12 channels), and 2x UARTs + 2x SPI + 2x I²C interfaces. It serves as a main system controller in industrial HMI, motor control edge nodes, and USB-connected sensor gateways.
For engineers reviewing the TM4C123GE6PZI datasheet, TM4C123GE6PZI pinout, TM4C123GE6PZI application, or TM4C123GE6PZI equivalent, key selection criteria include its integrated USB PHY, hibernation module with RTC and battery-backed memory, deterministic real-time interrupt latency (<12 cycles), and support for TivaWare C Series software stack.
Technical Context
The TM4C123GE6PZI integrates a single-core ARM Cortex-M4F with hardware floating-point unit (FPU), memory protection unit (MPU), and nested vectored interrupt controller (NVIC) supporting up to 80 interrupts. Its system-level peripherals include a hibernation module with deep-sleep current of 1.7 µA (RTC active), a μDMA controller with 32-channel arbitration, and a programmable clock tree with PLL, internal oscillator, and external crystal support (1–25 MHz).
On-chip analog includes a 12-bit, 1-MSPS ADC with four independent sample sequencers, hardware averaging, temperature sensor, and digital comparators. Digital I/O features configurable slew rate, drive strength, and GPIO commit registers enabling safe reconfiguration without glitching.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F401RE | ARM Cortex-M4F @ 84 MHz, 512 KB flash, no integrated USB PHY, requires external transceiver. | Lacks hibernation module and battery-backed RAM; lower analog integration (12-bit ADC, 1 MSPS, but only 16 channels, no hardware averaging). | Preferred when higher flash density and Ethernet MAC are needed; not suitable for USB-device-only designs without added PHY cost. |
| MSP432P401R | ARM Cortex-M4F @ 48 MHz, 2 MB flash, 256 KB SRAM, integrated USB PHY, ultra-low-power architecture (80 nA hibernate). | Lower CPU frequency limits real-time control throughput; superior low-power performance but reduced analog peripheral bandwidth (14-bit ADC, 1 MSPS, 16 channels). | Better for energy-constrained battery applications where compute load is moderate; less optimal for high-frequency PWM or USB bulk-transfer workloads. |
Compared with STM32F401RE and MSP432P401R, the TM4C123GE6PZI delivers balanced real-time performance, integrated USB connectivity, and industrial-grade hibernation - making it optimal for cost-sensitive, USB-centric embedded systems requiring robust analog acquisition and deterministic interrupt response.

FAQ
What is the maximum operating frequency of the TM4C123GE6PZI?
The TM4C123GE6PZI operates at a maximum CPU frequency of 80 MHz, achieved using its integrated PLL with external crystal (4–25 MHz) or internal precision oscillator. This frequency is fully supported across the entire –40°C to +85°C industrial temperature range and enables deterministic execution of real-time control loops with sub-microsecond jitter.
Does the TM4C123GE6PZI include an integrated USB physical layer?
Yes, the TM4C123GE6PZI includes a full-speed USB 2.0 physical layer (PHY) supporting device, host, and OTG modes. It requires no external transceiver and supports VBUS sensing, ID pin detection, and on-chip termination - verified in the official TI datasheet (SPMS374E, Section 1.3.3).
What is the hibernation current consumption of the TM4C123GE6PZI?
The TM4C123GE6PZI achieves 1.7 µA hibernation current with the real-time clock (RTC) active and battery-backed RAM enabled. This value is measured under specified conditions (VDD = 3.0 V, TA = 25°C) and confirmed in the Electrical Characteristics section of the SPMS374E datasheet (Table 4-19).
How many ADC channels does the TM4C123GE6PZI support, and what is its sampling rate?
The TM4C123GE6PZI supports 12 external ADC input channels with a maximum sampling rate of 1 million samples per second (1 MSPS). It features four independent sample sequencers, hardware averaging (up to 64 samples), and a built-in temperature sensor - all detailed in Section 13 of the SPMS374E datasheet.
Is the TM4C123GE6PZI pin-compatible with other Tiva C Series microcontrollers?
No, the TM4C123GE6PZI is not universally pin-compatible with other Tiva C Series parts. While it shares the 100-pin LQFP (PZ) footprint with variants like TM4C123GH6PZ, differences in peripheral mapping, power domain assignments, and reset behavior require board-level validation. Always consult the specific device datasheet and pin multiplexing table before substitution.
