Product Description
TM4C123GH6PM belongs to the ARM Cortex-M4 family. It operates at 80MHz, has 256 KB of Flash memory, 32 KB of single-cycle System SRAM, USB 2.0 (OTG, Host, Device), Up to 43 General purpose I/O pins, 6x32-bit timers, 2x12-bit A/D (12 channels), a 12-bit D/A , 8xUARTs, internal Realtime clock (RTC), 4xI2C, 4xSPI and 2xCAN controllers. It has Serial wire debug (SWD) and JTAG interfaces for programming and debugging.
8MHz crystal oscillator. We carefully chose the most convenient crystal value that provides clock frequency which can be used directly, or with the PLL multipliers to create higher MCU clock value.
32.768-kHz external crystal oscillator which provides external clock for the internal hibernation module.
