Connectivity covers CAN, I²C, SPI, SSI, UART, and IrDA. The 22-channel 12-bit ADC captures analog inputs without an external multiplexer.
Rated -40 to 85 °C ambient, the TM4C1231H6PZI7R suits factory-floor controllers and outdoor telecom pedestals. The 100-LQFP (14x14 mm) is a hand-solderable fine-pitch package.
The TM4C1231H6PZI7R carries an EOL Hot lifecycle stage.
80 MHz on the ARM Cortex-M4F core, with a single-precision floating-point unit for control-loop math.
No official pin-compatible replacement is listed in the record. A TM4C1233 or TM4C1294 variant may fit the same 100-LQFP footprint but differs in Flash density and peripheral set — verify pinout and register map against the target firmware before substituting.
The part is listed with a base product number TM4C1231; TI typically provides RoHS and REACH declarations on their product page. No UL or IEC certification is cited in this record.
