Product details
Overview
TM4C123BH6PMI 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, CAN, 8×PWM, 12-bit ADC (1MSPS), and multiple UART/SPI/I²C interfaces. It operates at 80 MHz and supports -40°C to +85°C industrial temperature range in a 64-pin LQFP package, used in motor control, industrial automation, and embedded HMI systems.
For engineers reviewing the TM4C123BH6PMI datasheet, TM4C123BH6PMI pinout, TM4C123BH6PMI application, or TM4C123BH6PMI equivalent, key selection criteria include its integrated USB PHY, dual CAN controllers, hibernation module with RTC and battery-backed memory, and support for TivaWare™ software ecosystem and TI's Code Composer Studio™ IDE.
Technical Context
The TM4C123BH6PMI integrates a 32-bit ARM Cortex-M4F core with hardware floating-point unit (FPU) and DSP extensions, enabling real-time signal processing and deterministic control loops. Its system-level integration includes a 200 MHz system clock derived from internal PLL, configurable GPIOs with slew-rate control, and a hibernation module supporting sub-μA sleep current with wake-on-RTC or external interrupt.
Peripherals are tightly coupled via the μDMA controller supporting 32-channel burst transfers, reducing CPU load during high-bandwidth operations like ADC sampling or USB data streaming. The analog subsystem features four independent 12-bit ADC modules with up to 12 sample sequencers, hardware averaging, and differential input capability-critical for precision sensor interfacing in closed-loop systems.

FAQ
What is the maximum operating frequency of the TM4C123BH6PMI?
The TM4C123BH6PMI operates at a maximum system clock frequency of 80 MHz, achieved via its internal PLL that accepts a 4–25 MHz crystal or external clock source. This frequency is sustained across the full industrial temperature range (-40°C to +85°C) and supports deterministic real-time execution of control algorithms and peripheral transfers. The TM4C123BH6PMI maintains timing compliance under all specified voltage (3.0–3.6 V) and thermal conditions per SPMS368E datasheet Section 5.2.5.
Does the TM4C123BH6PMI include an integrated USB physical layer (PHY)?
Yes, the TM4C123BH6PMI integrates a full-speed USB 2.0 OTG physical layer, eliminating the need for an external USB transceiver. It supports device, host, and OTG modes with VBUS sensing, ID pin detection, and on-chip termination resistors. This integration is confirmed in Section 14 of the SPMS368E datasheet and enables direct connection to USB cables without additional components - a key differentiator versus many competing Cortex-M4 MCUs.
How much SRAM and flash memory does the TM4C123BH6PMI provide?
The TM4C123BH6PMI includes 32 KB of on-chip SRAM and 256 KB of single-cycle flash memory, both accessible at full 80 MHz operation. The flash supports read-while-write (RWW) and has error correction coding (ECC) for enhanced reliability. Additionally, it provides 2 KB of EEPROM for wear-levelled nonvolatile storage - all verified in Section 8.2 of the SPMS368E datasheet and usable without external memory expansion in most embedded control applications.
What communication interfaces are supported by the TM4C123BH6PMI?
The TM4C123BH6PMI supports USB 2.0 OTG (with PHY), two CAN 2.0B controllers, eight UARTs, four SPI modules, and four I²C modules. Each interface is independently clocked and configurable via GPIO multiplexing. These capabilities are documented in Sections 1.3.3 and 14–19 of the SPMS368E datasheet and enable simultaneous use - for example, CAN for fieldbus, USB for PC interface, and I²C for sensor communication - without resource conflict.
Is the TM4C123BH6PMI qualified for industrial temperature operation?
Yes, the TM4C123BH6PMI is rated for operation from -40°C to +85°C ambient temperature, as specified in Section 1.3.8 (Packaging and Temperature) of the SPMS368E datasheet. It is offered in an industrial-grade 64-pin LQFP package with JEDEC-standard reflow profile compatibility and is intended for deployment in factory automation, motor drives, and outdoor equipment where extended thermal range is required.
