Product details
Overview
TM4C123GH6PM from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 80 MHz operation, 256 KB flash, 32 KB SRAM, integrated USB 2.0 OTG, dual CAN 2.0A/B controllers, and 12-bit ADC with 12 channels - deployed in industrial motor control, smart sensor nodes, and USB-connected embedded gateways.
For engineers reviewing the TM4C123GH6PM datasheet, TM4C123GH6PM pinout, TM4C123GH6PM application, or TM4C123GH6PM equivalent, key selection criteria include its deterministic floating-point performance, on-chip hibernation module for sub-μA sleep, USB device/host/OTG support, and dual-CAN capability for robust fieldbus communication in harsh environments.
Technical Context
The TM4C123GH6PM integrates a 32-bit ARM Cortex-M4F core with hardware FPU and NVIC supporting up to 80 interrupts, enabling real-time deterministic control loops. It features a multi-layer AHB bus matrix connecting CPU, μDMA, peripherals, and memory subsystems for concurrent data movement and processing.
Its system-level integration includes a programmable clock tree with PLL, multiple low-power modes (sleep, deep-sleep, hibernate), and dedicated hibernation module with RTC, battery-backed RAM, and external wake-up pins - all managed without CPU intervention.

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 crystal for USB. | Lacks hibernation module and dual CAN; offers higher CPU speed but larger footprint (100-pin LQFP). | Select when higher clock speed and larger flash are critical, and external USB PHY is acceptable. |
| MSP432P401RIPZT | ARM Cortex-M4F @ 48 MHz, 2 MB flash, integrated USB PHY, ultra-low-power hibernate (≤1.2 µA), no CAN. | Superior low-power performance and larger flash, but lacks CAN interfaces and operates at lower max frequency. | Select for battery-critical applications requiring USB and long runtime, where CAN is not needed. |
Compared with STM32F407VGT6 and MSP432P401RIPZT, the TM4C123GH6PM uniquely balances 80 MHz real-time performance, dual CAN, USB OTG with integrated PHY, and hibernation - making it optimal for space-constrained industrial gateways needing fieldbus interoperability and moderate power efficiency.

FAQ
What is the maximum operating frequency of the TM4C123GH6PM?
The TM4C123GH6PM operates at a maximum CPU frequency of 80 MHz, achieved via its on-chip PLL with external crystal or internal oscillator input. This frequency is fully supported across the industrial temperature range (–40°C to +105°C) and enables deterministic execution of real-time control tasks. The TM4C123GH6PM maintains timing integrity under full peripheral load, including simultaneous USB, CAN, and ADC activity.
Does the TM4C123GH6PM include an integrated USB physical layer?
Yes, the TM4C123GH6PM integrates a full-speed USB 2.0 physical layer (PHY) supporting device, host, and OTG modes. This eliminates the need for an external USB transceiver and simplifies layout and certification. The TM4C123GH6PM USB module complies with USB 2.0 specification and supports standard class drivers including CDC, HID, and MSC without additional silicon.
How much on-chip memory does the TM4C123GH6PM provide?
The TM4C123GH6PM includes 256 KB of on-chip flash memory for program storage, 32 KB of SRAM for runtime variables and stack, and 2 KB of EEPROM for non-volatile parameter storage. All memory blocks are accessible via the AHB bus with zero-wait-state operation at 80 MHz, and the EEPROM supports byte-level erase/write with 100K-cycle endurance.
What low-power modes are supported by the TM4C123GH6PM?
The TM4C123GH6PM supports Sleep, Deep-Sleep, and Hibernate modes. Hibernate mode draws ≤1.6 µA (typ) with RTC and 2 KB of battery-backed RAM active - enabling years of operation on coin-cell batteries. Wake-up sources include RTC alarm, external GPIO, and CAN activity. The TM4C123GH6PM exits hibernate in <5 µs, preserving system responsiveness.
Is the TM4C123GH6PM pin-compatible with other Tiva C Series microcontrollers?
No, the TM4C123GH6PM is not pin-compatible with other Tiva C Series variants such as TM4C1294NCPDT or TM4C1233H6PZ due to differing pin counts (144 vs. 128 vs. 100), package types, and peripheral mappings. While software is largely portable within the TivaWare SDK, hardware redesign is required for migration. The TM4C123GH6PM pinout is fixed per its 144-pin LQFP package definition in SPMS376E.
