EasyMx PRO
v7
Default MCU card
Microcontrollers are supported using specialized MCU cards containing 104 pins,
which are placed into the on-board female MCU socket. There are several types of
cards which cover all microcontroller families of Stellaris® Cortex
™
-M3, as well as
Cortex
™
-M4. The Default MCU card that comes with the EasyMx PRO
™
v7 package
is shown on Figure 4-1. It contains LM3S9B95 microcontroller which is loaded with
on-chip modules and is a great choice for both beginners and professionals. After
testing and building the nal program, this card can also be taken out of the board
socket and used in your nal device.
LM3S9B95 is the default chip of EasyMx PRO
™
v7. It belongs 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, ve 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 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 and dividers to create higher MCU clock value.
25MHz crystal oscillator. This crystal oscillator is connected to internal
Ethernet module.
VREF jumper. This jumper determines whether PB6 pin is used as voltage
reference for A/D converter, or it is used as general purpose I/O pin. Jumper is
soldered to VREF position by default.
Please note that if VREF jumper is resoldered 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.
