The TM4C1237E6PZI is a Texas Instruments Tiva™ C series 32-bit ARM Cortex-M4F microcontroller in a 100-LQFP package. On-chip peripherals include a 22-channel 12-bit ADC, a full CAN 2.0 controller, USB OTG, and multiple I²C, SPI, UART serial interfaces.
80 MHz Cortex-M4F — what it buys you
The single-precision FPU handles filter coefficients and trigonometric transforms without software emulation overhead.
Analog and I/O map for control applications
22 analog inputs at 12-bit resolution cover multi-channel sensor acquisition — thermocouples, strain gauges, current shunts — with enough headroom for one ADC channel per axis in a three-phase motor drive plus a few spare. The 69 GPIOs include pins muxed with the serial interfaces, CAN, and USB; plan the pin allocation early if you need all three CAN ports simultaneously with a parallel LCD bus.
