Product details
Overview
TM4C123GE6PZT from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 256 KB Flash, 32 KB SRAM, and integrated USB 2.0 OTG, PWM, ADC (12-bit, 1MSPS), and multiple serial interfaces (UART, SPI, I²C). It operates at up to 80 MHz and supports hibernation mode for ultra-low-power embedded control in motor drives and industrial sensing.
For engineers reviewing the TM4C123GE6PZT datasheet, TM4C123GE6PZT pinout, TM4C123GE6PZT application, or TM4C123GE6PZT equivalent, key selection criteria include its integrated USB PHY, 12-channel PWM with dead-band generation, 12-bit 1-MSPS ADC with hardware averaging, hibernation module with RTC and battery-backed memory, and support for ARM Thumb-2 and DSP instructions.
Technical Context
The TM4C123GE6PZT integrates a single-core ARM Cortex-M4F CPU with FPU, enabling deterministic floating-point math for real-time motion control. Its system-level integration includes a 16-channel μDMA controller, ROM-based bootloader, and programmable GPIOs with slew-rate and drive-strength control.
Peripherals are tightly coupled via the AHB/APB bus matrix: the 12-bit ADC supports four independent sample sequencers with digital comparators; the six GPTM modules provide flexible timing-PWM, input capture, one-shot, and RTC modes-with synchronized channel pairs for motor commutation.

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), lacks hibernation module | Better suited for high-throughput data processing; less optimal for battery-powered hibernate-wake cycles | Select when higher CPU performance and larger memory are critical, and USB host capability outweighs integrated PHY convenience |
| RP2040 | Dual-core ARM Cortex-M0+, 2 MB Flash, no FPU, no hibernation, USB 1.1 device-only, no analog peripherals (ADC requires external IC) | Targeted at cost-sensitive consumer devices; lacks industrial-grade analog and low-power features | Select for simple UI or lighting control where dual-core simplicity and low BOM cost outweigh precision analog and ultra-low-power needs |
Compared with STM32F407VGT6 and RP2040, the TM4C123GE6PZT uniquely balances USB OTG with integrated PHY, deterministic FPU math, and sub-2-µA hibernation-making it optimal for battery-aware industrial controllers where peripheral integration reduces component count and layout complexity.

FAQ
What is the maximum operating frequency of the TM4C123GE6PZT?
The TM4C123GE6PZT operates at a maximum system clock frequency of 80 MHz, achieved using its internal PLL with an external crystal (4–25 MHz) or internal 16-MHz RC oscillator. This frequency is sustained across the full industrial temperature range (–40°C to +105°C) and supports deterministic real-time execution of control loops and communication stacks.
Does the TM4C123GE6PZT include an integrated USB physical layer (PHY)?
Yes, the TM4C123GE6PZT includes a fully integrated USB 2.0 OTG physical layer, eliminating the need for an external transceiver. It supports device, host, and OTG roles, and handles differential signaling, termination, and VBUS detection internally-verified in the official TI datasheet section 14.3.1 and electrical characteristics table.
How much SRAM and Flash memory does the TM4C123GE6PZT have?
The TM4C123GE6PZT integrates 32 KB of on-chip SRAM and 256 KB of Flash memory with error-correcting code (ECC) protection. The Flash supports in-application programming (IAP), sector erase, and secure locking; the SRAM includes bit-band aliasing for atomic peripheral register access-details confirmed in Section 8.2 of the TI SPMS374E datasheet.
What low-power modes are supported by the TM4C123GE6PZT?
The TM4C123GE6PZT supports five low-power modes: Sleep, Deep-Sleep, Hibernate, LP-Deep-Sleep, and Shutdown. Hibernate mode draws just 1.6 µA while retaining RTC time and 256 bytes of battery-backed RAM. Wake-up sources include GPIO, external interrupts, RTC match, and USB activity-fully documented in Section 7 of the TI datasheet.
Can the TM4C123GE6PZT execute floating-point operations in hardware?
Yes, the TM4C123GE6PZT contains a single-precision IEEE 754-compliant Floating-Point Unit (FPU) tightly coupled to its ARM Cortex-M4F core. This enables cycle-accurate execution of trigonometric, exponential, and filtering functions-critical for motor control and sensor fusion-without software emulation overhead, as specified in Section 3.1.5 of the TI datasheet.
