Ethernet MCU card with LM3S9B95 (100-pin TQFP) v7 EasyMx PROCard information The Default MCU card that comes with the EasyMx PRO v7 for Stellaris package is shown on Figure 4-1. It contains LM3S9B95 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. LM3S9B95 is the default chip of EasyMx PRO v7 for Stellaris . It belongs 1 to ARM Cortex -M3 family. It has 80MHz operation, 256K bytes of linear program memory, 96K bytes of linear data memory. It has integrated Ethernet controller with PHY, USB (OTG, Host, Device), up to 65 General purpose I/O pins, five 16-bit timers, 16 Analog Input pins (AD), three UARTs, internal Real time clock (RTC), a pair of each: I2C, SPI and CAN controllers. It also contains 3 analog comparators, 16 digital comparators. It is pre loaded with StellarisWare libraries and bootloader in ROM. 2 8MHz crystal oscillator. We carefully chose the most convenient crystal 2 value that provides clock frequency which can be used directly, or with the PLL multipliers to create higher MCU clock value. 3 1 25MHz crystal oscillator. This crystal oscillator is connected to internal 3 Ethernet module. VREF jumper. This jumper determines whether PB6 pin is used as voltage 4 reference for A/D converter, or it is used as general purpose I/O pin. Jumper is soldered to VREF position by default. 4 Please note that if VREF jumper is soldered to I/O position Touch Panel controller will not operate correctly, because it uses voltage from this pin as a reference for A/D conversion.
