Product details

What this Tiva C MCU brings to the board

It carries 128 KB of Flash and 32K x 8 of SRAM, plus 2K x 8 of EEPROM. The 64-LQFP package (10x10 mm) is a common surface-mount footprint. With 49 I/O lines and connectivity including CAN, USB, I²C, SPI, and UART, this MCU fits into industrial control panels, motor drives, and HMI front-ends where a single chip handles both the control loop and the fieldbus interface. The internal oscillator and brown-out detect reduce external BOM count.

The 80 MHz core with FPU handles a PID loop with headroom for a Modbus stack and a 12-bit ADC conversion sequence.

Lifecycle status — plan ahead

Frequently asked questions

Is TM4C1232E6PMI7 obsolete?

The TM4C1232E6PMI7 is flagged as end-of-life (EOL hot). While the manufacturer still lists it as active, the lifecycle stage indicates last-time-buy. We can source remaining stock against an RFQ.

What is the pinout of TM4C1232E6PMI7?

The TM4C1232E6PMI7 uses a 64-LQFP package (10x10 mm) with 0.5 mm pitch. Pin 1 is at the chamfered corner. The device includes 49 I/O, 12-bit ADC inputs on Port B and Port E, and CAN/USB/SPI/I²C on dedicated pins.

What is the operating voltage of TM4C1232E6PMI7?

The TM4C1232E6PMI7 operates from 1.08 V to 3.63 V supply (Vcc/Vdd).

What is the difference between TM4C1232E6PMI7 and TM4C1233E6PMI7?

The TM4C1232E6PMI7 and TM4C1233E6PMI7 are pin-compatible Tiva C variants. The difference is typically in memory size or peripheral count—check the specific datasheet for Flash/RAM and USB or CAN feature set differences.
