Product details

Tiva C TM4C123GH6ZRBIR — 80 MHz Cortex-M4F with USB OTG and CAN

It packs 256 KB of Flash program memory, 32 KB of RAM, and 2 KB of EEPROM, plus a rich peripheral set including USB OTG, CANbus, multiple I²C/SPI/UART interfaces, and a 24-channel 12-bit ADC. The 157-ball BGA Microstar Junior package (9x9 mm) keeps the footprint tight for space-constrained industrial control boards, motor drives, and IoT gateway modules.

The 80 MHz core with FPU handles sensor fusion and PID loops. The 120 GPIO lines support parallel I/O to external ADCs or encoder interfaces.

The TM4C123GH6ZRBIR carries an end-of-life hot lifecycle status. No official replacement part number is listed in the evidence.

Frequently asked questions

Is TM4C123GH6ZRBIR obsolete?

The TM4C123GH6ZRBIR carries an end-of-life hot lifecycle flag, meaning a last-time-buy window may be active or imminent. The official product status is listed as Active, but the EOL hot indicator suggests planning for a replacement or final purchase is prudent.

What is the operating voltage of TM4C123GH6ZRBIR?

The supply voltage range is 1.08 V to 3.63 V, with 3.3 V being the typical rail for the I/O and analog blocks.

What is the package of TM4C123GH6ZRBIR?

The TM4C123GH6ZRBIR is supplied in a 157-ball VFBGA package (BGA Microstar Junior, 9x9 mm body). It is a surface-mount BGA requiring controlled reflow and X-ray inspection for solder joint verification.
