Product details

The TM4C123BH6PMIR is a Texas Instruments Tiva C Series 32-bit ARM Cortex-M4F MCU running at 80 MHz.

Peripheral set for industrial and panel applications

Connectivity covers CANbus for factory-floor networks, I²C and SPI for local sensor buses or an external serial Flash, and UART/USART for debug or Modbus RTU links. The quadrature encoder interface (QEI) reads incremental encoder pulses directly — no external counter logic needed for position feedback. 43 GPIOs in the 64-LQFP package leave enough pins for a parallel LCD interface or a bank of opto-coupled inputs. The 12-channel 12-bit ADC samples up to three phase currents plus a DC-link voltage in one conversion sequence.

Supply range is 1.08 V to 3.63 V.

Frequently asked questions

What is the operating temperature range of TM4C123BH6PMIR?

The operating temperature range is -40°C to 85°C, industrial grade.

What is the closest pin-compatible alternative to TM4C123BH6PMIR?

The non-tape-and-reel variant TM4C123BH6PM shares the same die and pinout; the suffix difference is packaging format only. For a different Flash/RAM density, the TM4C123x family uses the same 64-LQFP footprint.

Is TM4C123BH6PMIR RoHS compliant?

The part is supplied in Tape & Reel packaging; RoHS compliance is standard for this series. Confirm the specific date-code lot compliance at order placement.
