development system with lots of on-board peripherals
which allow development of devices with multimedia
contents. The central part of the system is a 32-bit
ARM®Cortex™-M4 TM4C123GH6PZ microcontroller.
The mikromedia for Tiva™C Series features integrated
modules such as stereo MP3 codec, TFT 320x240
touch screen display, accelerometer, MMC/SD card
slot, 8 Mbit ash memory, battery charger. The
board also contains MINI-B USB connector, two 1x26
connection pads and other. It comes pre-programmed
with USB HID bootloader, but can also be programmed
with external programmers, such as mikroProg™for
Tiva™C Series or other programmers. Mikromedia is
compact and slim, and perfectly ts in the palm of
your hand, which makes it a convenient platform for
mobile devices.

1. Power supply
You can power up the board using the MINI-B
USB cable provided in the package. On-board
voltage regulators provide the appropriate
voltage levels to each component on the
board. Power LED (GREEN) will indicate the
presence of a power supply.
You can also power the board with a Li-Polymer battery,
using the on-board battery connector. On-board battery
charger circuit MCP73832 enables you to charge the
battery over the USB connection. LED diode (RED) will
indicate when the battery is charging. Charging current is
~250mA and charging voltage is 4.2V DC.

The microcontroller is preprogrammed with USB HID Bootloader,
which can be used to upload new device rmware. To transfer
rmware .HEX le from a PC to an MCU you need to use the mik-
roBootloader USB HID application, which can be downloaded from:
Upon download, unzip the package to a desired location and start
the mikroBootloader application:
In order to start, connect the USB cable or (if already
connected) press the Reset button on your board.
Click the Connect button within 5s to enter the bootloader
mode, otherwise the existing program will execute.

mikromedia for Tiva™C Series is equipped with a reset button, which is located at the top of the front side (Figure 4-2). If you want to
reset the circuit, press the reset button. It will generate a low voltage level on the microcontroller reset pin (input). In addition, a reset
can be externally provided through pin 27 on side headers (Figure 4-3).

5. Crystal oscillator
The use of crystal in all other schematics is implied even if it is purposely left out, because of the schematics clarity.
NOTE:
mikromedia for Tiva™C Series is equipped with a 16MHz
crystal oscillator (X1) circuit that provides an external clock
waveform to the microcontroller OSC0 and OSC1 pins. This base
frequency is suitable for further clock multipliers and is ideal for generation
of the necessary USB clock, which ensures proper operation of bootloader and
your custom USB-based applications. Board also contains 32.768kHz Crystal
oscillator (X2) which provides external clock for the internal hibernation module.
