Product details

ARM Cortex-M4F at 80 MHz — control-loop headroom

Program memory is 256 KB of Flash, paired with 32 KB of SRAM and 2 KB of EEPROM. The Flash holds firmware for field-updatable industrial controllers; the SRAM supports moderate buffering for USB OTG or CAN data streams.

Connectivity and I/O — CAN, USB OTG, and serial options

The CAN + USB OTG combination is a common pairing for industrial gateways that bridge a fieldbus to a local HMI or data-logger. The QEI (quadrature encoder interface) is a direct hookup for motor-feedback encoders. There are 43 general-purpose I/O lines, enough for a modest control panel with discrete sensors and actuators.

Supply range spans 1.08 V to 3.63 V. Internal oscillator means no external crystal is required for basic operation.

Frequently asked questions

What is the closest pin-compatible alternative to TM4C123GH6PMI7 in this component family?

Within the Tiva C series, the TM4C123GH6PZ (100-LQFP) offers the same core and Flash but with more I/O and a larger package. For a direct 64-LQFP pin-compatible drop-in, look at the TM4C1231H6PM — same Flash and SRAM, but without the full set of connectivity options. Verify the peripheral list against your BOM before swapping.

What is TM4C123GH6PMI7's listed speed (80 MHz) on this component line?

The TM4C123GH6PMI7 runs at 80 MHz maximum clock speed. That is the core frequency for the ARM Cortex-M4F, delivering roughly 100 MIPS with the single-cycle multiply and FPU active.

What is TM4C123GH6PMI7's listed series (Tiva C) on this component line?

The TM4C123GH6PMI7 belongs to the Tiva C series from Texas Instruments. This series is built around ARM Cortex-M4F cores with integrated CAN, USB, and analog peripherals, targeting industrial control and motor drive applications.

What compliance documentation does this brand provide for TM4C123GH6PMI7 (RoHS, REACH, UL, IEC)?

Texas Instruments provides RoHS and REACH compliance declarations for the TM4C123GH6PMI7. The part is lead-free and the 64-LQFP package is compatible with standard lead-free reflow profiles. UL and IEC certifications are not typically issued for individual ICs; system-level safety certification (e.g., IEC 61508) depends on the end-application design.
