LM4F232H5QD belongs to ARM® Cortex™-M4 family. It has 80MHz operation, 256K bytes of flash memory , 32K bytes of SRAM memory and 2K bytes of EEPROM memory. It has USB (OTG, Host, Device), up to 105 General purpose I/O pins, 16/32-bit timers, 2 12-bit ADC modules, 8 UARTs, internal Real time clock (RTC), 6 I2C, 4 SPI and 2 CAN controllers. It also contains 3 analog comparators and 16 digital comparators. It is preloaded with StellarisWare® libraries and bootloader in ROM.
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.
MCU card also contains 32.768 kHz crystal oscillator which provides external clock waveform for RTCC module.
