It packs 256 KB of Flash program memory, 32 KB of SRAM, and 2 KB of EEPROM, plus a 24-channel 12-bit ADC, CAN, I²C, SPI, UART, and QEI peripherals. This is the part you spec into a motor-drive control board, a factory automation I/O module, or a medical pump controller that needs floating-point math and a rich peripheral set on a single chip. The 120 GPIOs and 157-ball BGA package (Microstar Junior, 9x9 mm) suit it for designs where board space is tight but I/O count is high.
The 80 MHz ARM Cortex-M4F core with FPU handles single-precision math natively, reducing cycle count for control algorithms.
The TM4C123BH6ZRBI7R is flagged as end-of-life (EOL hot). Texas Instruments has not published a last-time-buy deadline on this listing.
What is in the peripheral set
Connectivity covers CAN, I²C, SPI, SSI, UART, IrDA, and Microwire — enough to talk to most industrial sensors, motor encoders, and display modules. The 24-channel 12-bit ADC with up to 2 MSPS samples multiple analog inputs in sequence without external muxing. Motion PWM and QEI are purpose-built for brushless DC motor control.
