80 MHz Cortex-M4F with FPU — what it does on the board
The 105 I/O pins break out to CAN, USB, multiple UART/SPI/I²C interfaces, and a 24-channel 12-bit ADC — enough connectivity for a mid-complexity industrial controller or an automotive body-domain node.
80 MHz — what it buys in a control loop
144-LQFP — board fit and thermal notes
The 144-LQFP package (20x20 mm body) is a standard footprint. The 105 I/O pins fan out to four sides. Supply range is 1.08 V to 3.63 V.
The TM4C1233H6PGEI7 is marked as end-of-life hot (EOL). Sourcing runs through independent distribution and surplus channels. We source this part to order against an RFQ.
