Product details

The TM4C123BH6PZI7 runs an ARM Cortex-M4F core at 80 MHz with a single-precision floating-point unit. 256 KB of Flash and 32 KB of SRAM leave room for a CANopen or Modbus stack plus a few control tasks; the 2 KB EEPROM holds calibration constants or boot counters without wearing the Flash.

Connectivity covers CAN, I²C, SPI, SSI, UART, and IrDA — enough to bridge a CANopen fieldbus to a serial display or a Microwire EEPROM.

Lifecycle: end-of-life phase — plan the BOM transition

This part is flagged as end-of-life (EOL). TI has issued a last-time-buy window; after that, the only channel is surplus or independent distribution.

Frequently asked questions

What is the closest pin-compatible alternative to TM4C123BH6PZI7?

Within the Tiva C TM4C123 family, the TM4C123GH6PMI shares the same 100-LQFP footprint and peripheral set but offers 256 KB Flash and 32 KB SRAM — verify the exact memory map and any firmware changes. For a higher-performance path, the TM4C1294NCPDT adds Ethernet but uses a different pinout.

What is TM4C123BH6PZI7's listed speed?

The core runs at 80 MHz with a single-precision FPU — enough for real-time control loops and sensor fusion without external DSP.

What is TM4C123BH6PZI7's series?

It belongs to the Tiva C series from Texas Instruments, built around the ARM Cortex-M4F architecture.
