On-chip CAN controller and QEI handle motor-feedback and fieldbus interface. 24-channel 12-bit ADC samples current-sense resistors and thermistor inputs. Brown-out detect and POR are integrated.

Lifecycle status — EOL, plan the last-time buy

Flagged as end-of-life (EOL). Manufacturer has issued a last-time-buy notice. For a BOM that already qualifies this part, secure the lifetime buy quantity or identify a migration path. No direct drop-in replacement exists in the same 144-LQFP footprint. Sourcing through independent distribution is the channel for post-EOL replenishment.

Frequently asked questions

What is the closest pin-compatible alternative to TM4C123BH6PGEI7R?

There is no direct pin-compatible drop-in replacement in the Tiva C family for the 144-LQFP package. The TM4C123GH6PMI7R shares the same core and memory but uses a 64-pin LQFP, requiring a board redesign. No second-source alternate is listed in the official documentation.

What is TM4C123BH6PGEI7R's listed speed?

The TM4C123BH6PGEI7R is rated for 80 MHz operation on the ARM Cortex-M4F core.
