It operates at 80 MHz and supports industrial temperature range (–40°C to +85°C) in a 64-pin LQFP package, used in motor control, industrial automation, and embedded HMI systems.
For engineers reviewing the TM4C123FH6PMI7 datasheet, TM4C123FH6PMI7 pinout, TM4C123FH6PMI7 application, or TM4C123FH6PMI7 equivalent, key selection criteria include its 80 MHz Cortex-M4F core with FPU, on-chip USB PHY, dual CAN 2.0B controllers, 12-bit 1-MSPS ADC with 12 input channels, and support for TivaWare™ software stack in real-time embedded designs.
Technical Context
The TM4C123FH6PMI7 integrates an ARM Cortex-M4F core with single-precision floating-point unit and memory protection unit, enabling deterministic real-time execution. Its system-level integration includes a programmable clock tree with PLL, power gating per peripheral, and configurable GPIOs with slew-rate control and 5-V-tolerant inputs on select pins.
Peripherals are tightly coupled via the μDMA controller supporting 32-channel arbitration and scatter-gather transfers. Analog subsystem includes two independent 12-bit ADC modules with hardware averaging, digital comparators, and internal temperature sensor - all synchronized to PWM timers for motion control feedback loops.

FAQ
What is the maximum operating frequency of the TM4C123FH6PMI7?
The TM4C123FH6PMI7 operates at a maximum system clock frequency of 80 MHz, derived from an internal precision oscillator or external crystal with PLL multiplication. This frequency is sustained across the full industrial temperature range (–40°C to +85°C) and supports deterministic real-time execution of control loops and communication stacks in the TM4C123FH6PMI7.
Does the TM4C123FH6PMI7 include an integrated USB physical layer?
Yes, the TM4C123FH6PMI7 integrates a full-speed USB 2.0 physical layer (PHY) with on-die termination resistors and a 1.5-kΩ pull-up resistor on D+ - eliminating the need for external USB transceivers in device, host, or OTG configurations. This integration reduces bill-of-materials cost and PCB layout complexity for the TM4C123FH6PMI7.
How many CAN interfaces does the TM4C123FH6PMI7 support?
The TM4C123FH6PMI7 supports two independent CAN 2.0B controllers (CAN0 and CAN1), each with dedicated message objects, FIFOs, and bit-rate configuration registers. These controllers enable concurrent communication on separate CAN buses - a capability confirmed in the TM4C123FH6PMI7 datasheet section 15.3 and used in automotive diagnostic tools and industrial network gateways.
What is the ADC resolution and sampling rate of the TM4C123FH6PMI7?
The TM4C123FH6PMI7 features two 12-bit successive approximation register (SAR) ADC modules, each capable of up to 1 million samples per second (1 MSPS) with hardware averaging across up to 64 samples. This specification is validated in the TM4C123FH6PMI7 datasheet section 12.3.4 and supports high-fidelity current/voltage sensing in motor control and power monitoring applications.
Is the TM4C123FH6PMI7 pin-compatible with other Tiva C Series microcontrollers?
No, the TM4C123FH6PMI7 is not universally pin-compatible with other Tiva C Series devices. While it shares the 64-pin LQFP package with some variants (e.g., TM4C123GH6PM), pin functions differ significantly across memory sizes and peripheral sets. The TM4C123FH6PMI7 datasheet confirms unique pin mappings for USB, CAN, and ADC signals - requiring board-specific layout for the TM4C123FH6PMI7.
