It operates at 80 MHz, supports -40°C to +105°C industrial temperature range, and is used in motor control, industrial automation, and embedded HMI systems.
For engineers reviewing the TM4C123FH6PMT7R datasheet, TM4C123FH6PMT7R pinout, TM4C123FH6PMT7R application, or TM4C123FH6PMT7R equivalent, key selection criteria include its integrated USB PHY, dual CAN 2.0B controllers, deterministic real-time performance via FPU and NVIC, and support for TivaWare™ software stack in safety-critical edge nodes.
Technical Context
The TM4C123FH6PMT7R implements a 32-bit ARM Cortex-M4F core with hardware floating-point unit (FPU) and nested vectored interrupt controller (NVIC), enabling deterministic execution of control loops and signal processing tasks. It integrates a programmable system clock up to 80 MHz using PLL-based frequency synthesis from internal or external sources.
On-chip analog subsystem includes two independent 12-bit ADCs with sample rates up to 1 MSPS per channel and configurable sequencers; digital peripherals include USB Device/Host/OTG with integrated PHY, two CAN 2.0B controllers, eight 16/32-bit general-purpose timers, and μDMA supporting 32-channel arbitration for zero-CPU-overhead peripheral transfers.

FAQ
What is the maximum operating temperature specification for the TM4C123FH6PMT7R?
The TM4C123FH6PMT7R is rated for operation from -40°C to +105°C ambient temperature. This industrial-grade temperature range is verified per TI's production test flow and supports deployment in engine compartments, factory floors, and outdoor enclosures without thermal derating. The TM4C123FH6PMT7R maintains full electrical specifications-including 80 MHz CPU speed and ADC accuracy-across this entire range.
Does the TM4C123FH6PMT7R include an integrated USB physical layer (PHY)?
Yes, the TM4C123FH6PMT7R integrates a full-speed USB 2.0 PHY compliant with USB Specification Revision 2.0. This eliminates the need for an external transceiver chip in USB Device, Host, or OTG configurations. The TM4C123FH6PMT7R supports plug-and-play enumeration, suspend/resume, and battery charging detection (BCD) mode when configured appropriately in firmware.
How many CAN controllers does the TM4C123FH6PMT7R support, and what protocol versions are implemented?
The TM4C123FH6PMT7R includes two independent CAN controllers compliant with the CAN 2.0B protocol standard, supporting both standard (11-bit) and extended (29-bit) identifier frames. Each controller features dedicated message RAM, acceptance filtering, and error counters. The TM4C123FH6PMT7R does not implement CAN FD; however, its dual CAN architecture enables redundant networking or functional segregation (e.g., one bus for control, one for diagnostics).
What is the ADC resolution and maximum sampling rate of the TM4C123FH6PMT7R?
The TM4C123FH6PMT7R integrates two 12-bit successive-approximation ADCs, each capable of up to 1 million samples per second (1 MSPS). Each ADC has eight programmable sample sequencers with configurable trigger sources and hardware averaging (2–64 samples). The TM4C123FH6PMT7R supports both single-ended and differential input modes, and includes an internal temperature sensor with ±3°C accuracy across the full temperature range.
Is the TM4C123FH6PMT7R pin-compatible with other devices in the TM4C123x family?
Yes, the TM4C123FH6PMT7R shares the same 100-pin LQFP package and pinout with other TM4C123x variants that use the 'PMT' suffix (e.g., TM4C123GH6PMT, TM4C123BH6PMT), differing only in flash/RAM size and peripheral enablement. Pin compatibility allows direct substitution within the same package footprint, provided firmware accounts for differences in memory mapping and peripheral availability. The TM4C123FH6PMT7R is not pin-compatible with QFP or BGA variants in the same family.
