The TM4C123GE6PZT: The FPU accelerates single-precision math loops — sensor fusion, motor-control PID, or audio filter coefficients — without cycle-counting software emulation. Program memory is 128 KB of Flash, backed by 32K x 8 SRAM and 2K x 8 EEPROM for nonvolatile parameter storage. The 100-LQFP package brings out 69 I/O lines, including a 22-channel 12-bit ADC.
Industrial temperature rating and deployment envelope
Internal oscillator is available, but an external clock or crystal can be used when tighter timing accuracy is needed.
On-chip peripherals include CAN, USB OTG, multiple UART/USART, I²C, SPI, SSI, and a quadrature encoder interface (QEI) for motor position feedback. The 22-channel 12-bit ADC can sample multiple analog inputs without external muxing.
