Product details
Overview
TM4C123GE6PZT7 from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 256 KB flash, 32 KB SRAM, and integrated peripherals including USB 2.0, CAN, 8×PWM, 12-bit ADC (1MSPS), and dual QEI - deployed in industrial motor control, smart sensor nodes, and USB-connected embedded gateways.
For engineers reviewing the TM4C123GE6PZT7 datasheet, TM4C123GE6PZT7 pinout, TM4C123GE6PZT7 application, or TM4C123GE6PZT7 equivalent, key selection criteria include its 80 MHz operation, hibernation module with RTC and battery-backed memory, JTAG/SW-DP debug interface, and support for TivaWare™ software stack in real-time deterministic applications.
Technical Context
The TM4C123GE6PZT7 integrates a single-core ARM Cortex-M4F CPU with hardware floating-point unit (FPU) and NVIC supporting up to 80 interrupts. It features a configurable system clock tree with PLL, internal precision oscillator (±1%), and multiple low-power modes (sleep, deep-sleep, hibernate).
Peripherals include two USB controllers (one OTG-capable), two CAN 2.0B modules, eight 16/32-bit general-purpose timers, four UARTs (with IrDA and ISO 7816), two I²C, two SPI, and a 12-channel 12-bit ADC with hardware averaging and digital comparators.

Pinout & Package
TM4C123GE6PZT7 uses a 100-pin LQFP package (14 × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are defined per TI SPMS374E datasheet Rev E (June 2014), with dedicated VDDA/VSSA for analog supply isolation and multiple GPIO groups supporting peripheral multiplexing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VDDC | Power supply inputs | Separate domains for digital core (VDD), analog (VDDA), and USB PHY (VDDC) - enable noise-sensitive ADC and USB operation simultaneously. |
| PD0–PD7, PE0–PE5, etc. | GPIO with peripheral multiplexing | Each port supports up to 8 alternate functions (e.g., UART0_TX, PWM0_0, SSI0_CLK) - allows flexible board routing and peripheral sharing. |
| USB0_P/N | Differential USB 2.0 data pair | Integrated USB PHY eliminates need for external transceiver - reduces BOM count and layout complexity. |
| OSC0/OSC1 | Crystal oscillator input/output | Supports 4–25 MHz crystal or external clock - provides precise timing source for USB, CAN, and RTC. |
| NMI, RESET | Non-maskable interrupt and reset input | Asynchronous NMI enables emergency fault handling; RESET supports both power-on and software-triggered reset sequences. |
Key Features
| Feature | Design Value |
|---|---|
| Hibernate Module | Retains RTC, 2 KB RAM, and wake-on-RTC-match or GPIO with <1 µA current - enables multi-year battery operation in wireless sensors. |
| USB OTG Controller | On-chip PHY and OTG session request protocol (SRP) support - allows self-powered device enumeration and host negotiation without external IC. |
| QEI Interfaces | Dual quadrature encoder interfaces with 32-bit position counter and velocity capture - directly interfaces to rotary encoders in motor feedback loops. |
| Peripheral Gate Control | Run-time clock gating per peripheral via RCGC registers - reduces dynamic power by disabling unused modules without firmware overhead. |
| TivaWare™ Support | TI-provided driver library, USB stack, and FreeRTOS integration - accelerates development of USB HID devices, CAN gateways, and motor control firmware. |
Applications
| Industrial Motor Control | Smart Sensor Gateway |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TM4C1294NCPDT | ARM Cortex-M4F @ 120 MHz, 1 MB flash, 256 KB SRAM, integrated Ethernet MAC + PHY, no CAN | Better suited for Ethernet-connected HMI or gateway applications; lacks CAN but adds Gigabit Ethernet capability | Select when Ethernet connectivity outweighs CAN requirement and higher memory is needed for web server or TLS stack. |
| STM32F407VGT6 | ARM Cortex-M4F @ 168 MHz, 1 MB flash, 192 KB SRAM, USB OTG HS, no hibernate RTC or battery-backed RAM | Higher performance and memory, but no integrated hibernate module - requires external RTC/battery for low-power wake-up | Choose for compute-intensive tasks (e.g., audio codec, FFT) where ultra-low hibernate current is not required. |
Compared with TM4C123GE6PZT7, TM4C1294NCPDT trades CAN for Ethernet and scales memory for richer firmware, while STM32F407VGT6 delivers higher CPU throughput but lacks on-chip hibernate retention - making TM4C123GE6PZT7 optimal for cost-sensitive, battery-aware CAN/USB edge nodes.

FAQ
What is the maximum operating frequency of the TM4C123GE6PZT7?
The TM4C123GE6PZT7 operates at a maximum system clock frequency of 80 MHz, achieved using its internal PLL with a 4–25 MHz crystal or external clock source. This frequency applies to the ARM Cortex-M4F core, bus matrix, and most peripherals - all rated for full-speed operation at this rate per TI SPMS374E datasheet Section 5.2.5.
Does the TM4C123GE6PZT7 support USB device, host, and OTG modes?
Yes, the TM4C123GE6PZT7 includes a USB 2.0 OTG controller with integrated PHY, supporting device, host, and OTG roles. Its USB module complies with USB 2.0 specification and implements Session Request Protocol (SRP) and Host Negotiation Protocol (HNP), enabling dynamic role switching - confirmed in Section 14 of the SPMS374E datasheet.
How much SRAM and flash memory does the TM4C123GE6PZT7 have?
The TM4C123GE6PZT7 integrates 32 KB of on-chip SRAM and 256 KB of single-cycle flash memory. Additionally, it includes 2 KB of EEPROM for nonvolatile parameter storage. These memory resources are mapped into the ARM Cortex-M4F address space and accessible without external bus interface - as specified in Section 8.2 of the SPMS374E datasheet.
What low-power modes are available on the TM4C123GE6PZT7?
The TM4C123GE6PZT7 supports Sleep, Deep-Sleep, and Hibernate modes. Hibernate mode retains RTC, 2 KB of battery-backed RAM, and wake capability via GPIO or RTC match with typical current draw below 1 µA - detailed in Section 7 of the SPMS374E datasheet. No external RTC or backup capacitor is required for basic hibernate functionality.
Is the TM4C123GE6PZT7 pin-compatible with other TM4C123 devices?
The TM4C123GE6PZT7 shares the same 100-pin LQFP package and pinout with other TM4C123x PZ-series variants (e.g., TM4C123GH6PZ, TM4C123BE6PZ), differing only in flash size, SRAM, and feature enablement. Pin compatibility is guaranteed within the PZ package family per TI's migration guidelines in the TM4C123x datasheet revision history.
