LM4F MCU card with LM4F232H5QD (144-pin TQFP) v7 EasyMx PROCard information The LM4F MCU card is shown on Figure 1. It contains LM4F232H5QD microcontroller with on-chip peripherals and is a great choice for both beginners and professionals. After testing and building the final program, this card can also be taken out of the board socket and used in your final device. LM4F232H5QD belongs to ARM Cortex -M4 family. It has 80MHz 8MHz crystal oscillator. We carefully chose the most convenient crystal 1 2 operation, 256K bytes of flash memory , 32K bytes of SRAM memory and value that provides clock frequency which can be used directly, or with the 2K bytes of EEPROM memory. It has USB (OTG, Host, Device), up to 105 PLL multipliers to create higher MCU clock value. 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 3 MCU card also contains 32.768 kHz crystal oscillator which provides contains 3 analog comparators and 16 digital comparators. It is preloaded external clock waveform for RTCC module. with StellarisWare libraries and bootloader in ROM.
