1.1 Microcontroller programming/debugging
The host MCU can be programmed and debugged over the JTAG/SWD
compatible 2x5 pin header (2), labeled as PROG/DEBUG. This header
allows an external programmer (e.g. CODEGRIP or mikroProg) to be used.
To enable the JTAG interface, two SMD jumpers labeled as JP3 and JP4 (3)
must be populated. These jumpers are unpopulated by default, optimizing
the pin count so that more pins could be used for a large number of
MC U s F E AT U RE S
onboard modules and peripherals.

Programming the microcontroller can also be done by using the bootloader
which is preprogrammed into the device by default. All the informations
about the bootloader software can be found on the following page:

2. Power supply unit
The power supply unit (PSU) provides clean and regulated
power, necessary for proper operation of the mikromedia 5
development board. The host MCU, along with the rest of the
peripherals, demands regulated and noise-free power supply.
Therefore, the PSU is carefully designed to regulate, filter,
and distribute the power to all parts of mikromedia 5. It is
POWE R S U P P LY
equipped with four different power supply inputs, offering all
the flexibility that mikromedia 5 needs, especially when used
on the field or as an integrated element of a larger system. In
the case when multiple power sources are used, an automatic
power switching circuit with predefined priorities ensures that
the most appropriate will be used.
PAGE 9
The PSU also contains a reliable and safe battery charging
circuit, which allows a single-cell Li-Po/Li-Ion battery to be
charged. Power OR-ing option is also supported, providing
an uninterrupted power supply (UPS) functionality when an
external or USB power source is used in combination with the
battery.

voltage power sources (a Li-Po/Li-Ion battery and USB), allowing the next
stage to deliver well-regulated 3.3V and 5V to the development board. A set
of discrete components are used to determine if the input power source
requires a voltage boost. When multiple power sources are connected
at once, this circuitry is also used to determine the input priority level:
externally connected 12V PSU, power over USB, and the Li-Po/Li-Ion battery.
P A G E 10
The transition between available power sources is designed to provide
uninterrupted operation of the development board.
The next PSU stage uses two MIC28511, synchronous step-down (buck)
regulators, capable of providing up to 3A. The MIC28511 IC utilizes the
HyperSpeed Control® and HyperLight Load® architectures, providing an
ultra-fast transient response and high light-load efficiency. Each of the two
buck regulators is used to supply power to the corresponding power supply
rail (3.3V and 5V), throughout the entire development board and connected
peripherals.

2.3 PSU connectors
As explained, the advanced design of the PSU allows several types of power
sources to be used, offering unprecedented flexibility: when powered
by a Li-Po/Li-Ion battery, it offers an ultimate degree of autonomy. For
situations where the power is an issue, it can be powered by an external
12VDC power supply, connected over the 5.5mm barrel connector or over
the two-pole screw terminal. Power is not an issue even if it is powered
over the USB cable. It can be powered over the USB-C connector, using
power supply delivered by the USB HOST (i.e. personal computer), USB wall

optimal amount of power, since one external power supply unit can be easily
exchanged with another, while its power and operating characteristics can
be decided per application. The development board allows a maximum
current of 2.8A per power rail (3.3V and 5V) when using an external 12V
power supply. The barrel-type connector is useful for connecting walladapters, while the screw terminal is a good choice when there is no
connector installed at the end of the PSU cable.
12V barrel-type connector and screw terminal should not be used
simultaneously by two different power supplies, as the connectors
are routed in parallel.

After a valid power supply source is connected (1) in our case with a singlecell Li-Po/Li-Ion battery, mikromedia 5 can be powered ON. This can be
done by a small switch at the edge of the board, labeled as SW1 (2). By
switching it ON, the PSU module will be enabled, and the power will be
distributed throughout the board. A LED indicator labeled as PWR indicates
that the mikromedia 5 is powered ON.

The mikromedia 5 development board is equipped with two
STO RAGE
types of storage memory: with a microSD card slot and a
Flash memory module.
P A G E 18
4.1 microSD card slot

The microSD card slot (1) allows storing large amounts of data externally,
on a microSD memory card. It uses the Serial Peripheral Interface (SPI) for
communication with the MCU. The microSD card detection circuit is also
provided on the board. The microSD card is the smallest SD Card version,
measuring only 5 x 11 mm. Despite its small size, it allows tremendous
amounts of data to be stored on it. In order to read and write to the SD
Card, a proper software/firmware running on the host MCU is required.
4.2 External flash storage
mikromedia 5 is equipped with the SST26VF064B Flash memory (2). The
Flash memory module has a density of 64 Mbits. Its storage cells are
arranged in 8-bit words, resulting in 8Mb of non-volatile memory in total,
available for various applications. The most distinctive features of the
SST26VF064B Flash module are its high speed, very high endurance, and
very good data retention period. It can withstand up to 100,000 cycles, and
it can preserve the stored information for more than 100 years. It also uses
the SPI interface for the communication with the MCU.

5. Connectivity
mikromedia 5 offers a huge number of connectivity options.
It includes support for the Ethernet, WiFi, RF and USB (HOST/
DEVICE). Besides those options, it also offers two 1x26 pin
headers, which are used to directly access the MCU pins.
Ethernet is a popular computer networking technology for local area
networks (LAN). Systems communicating over Ethernet divide a stream of
data into individual packets, known as frames. Each frame contains source
and destination addresses and error-checking data so that damaged data
can be detected and re-transmitted. This makes the Ethernet protocol very
popular for communication over longer distances or in noisy environments.
The host MCU features an integrated Ethernet peripheral module, which
contains the entire communication stack on-chip. The physical layer is
provided by the LAN8720A, an RMII 10/100 Mbit Ethernet PHY IC from
Microchip. This IC has many useful features, including flexPWR® technology
with a flexible power management architecture and a support for various
low-power modes, compliance with ISO 802-3/IEEE and IEEE802.3/802.3u

equipped with two LED indicators, which are located on the front side. They
are used to signal status and data traffic.
P A G E 19
5.1 Ethernet
5.2 RF
mikromedia 5 offers communication over the world-wide ISM radio band.
The ISM band covers a frequency range between 2.4GHz and 2.4835GHz.
This frequency band is reserved for industrial, scientific, and medical use
(hence the ISM abbreviation). In addition, it is globally available, making it
a perfect alternative to WiFi, when the M2M communication over a short
distance is required.
mikromedia 5 uses the nRF24L01+ (1), a single-chip 2.4GHz transceiver
CO N N E CT IVIT Y
with an embedded baseband protocol engine, produced by Nordic
Semiconductors. It is a perfect solution for ultra-low power wireless
applications. This transceiver relies on the GFSK modulation, allowing data
rates in the range from 250 kbps, up to 2 Mbps. The GFSK modulation
is the most efficient RF signal modulation scheme, reducing the required
bandwidth, thus wasting less power. The nRF24L01+ also features a
proprietary Enhanced ShockBurst™, a packet-based data link layer.
Besides other functionalities, it offers a 6-channel MultiCeiver™ feature,
which allows using the nRF24L01+ in a star network topology. The
P A G E 20
nRF24L01+ uses the SPI interface to communicate with the host MCU.
Along the SPI lines, it uses additional GPIO pins for the SPI Chip Select,
Chip Enable, and for the interrupt. The RF section of the mikromedia 5
also features a small chip antenna (4), reducing the need for additional
hardware components.

5.3 WiFi
A very popular WiFi module (2) labeled as CC3100 allows WiFi connectivity.
This module is the complete WiFi solution on a chip: it is a powerful WiFi
network processor with the power management subsystem, offering the
TCP/IP stack, powerful crypto engine with 256-bit AES support, WPA2
security, SmartConfig™ technology, and much more.
By offloading the WiFi and Internet handling tasks from the MCU, it allows
the host MCU to process more demanding graphical applications, thus
It uses the SPI interface to communicate with the host MCU, along with
several additional GPIO pins used for the reset, hibernation, and for the
interrupt reporting.
An SMD jumper labeled as FORCE AP (3) is used to force the CC3100
module into an Access Point (AP) mode, or into a Station mode. However,
the operating mode of the CC3100 module can be overridden by the
CO N N E CT IVIT Y
making it an ideal solution for adding WiFi connectivity to mikromedia 5.

NOTE
5.5 1x26 pin headers
Most of the host MCU pins are routed to the two 1x26 pin headers (2), making them available for further connectivity. In addition to MCU pins, some
additional peripheral pins are also routed to this header.
Besides the ability to connect various external devices and peripherals by using wire jumpers, these pins also allow using shields with the additional

6. Sound-related peripherals
By offering a pair of sound-related peripherals, mikromedia 5
rounds-up its multimedia concept. It features a piezo-buzzer,
which is extremely easy to program but can produce only the
simplest sounds, useful only for alarms or notifications.
The second audio option is the powerful VS1053B IC (1). It is

an Ogg Vorbis/MP3/AAC/WMA/FLAC/WAV/MIDI audio decoder,
and a PCM/IMA ADPCM/Ogg Vorbis encoder, both on a single
chip. It features a powerful DSP core, high-quality A/D and
D/A converters, stereo headphones driver capable of driving
a 30Ω load, zero-cross detection with the smooth volume

change, bass and treble controls, and much more.
6.1 Piezo buzzer
A piezo buzzer (2) is a simple device capable of reproducing sound. It
is driven by a small pre-biased transistor. The buzzer can be driven by
applying a PWM signal from the MCU at the base of the transistor: the
pitch of the sound depends on the frequency of the PWM signal, while the
volume can be controlled by changing its duty cycle. Since it is very easy to
program, it can be very useful for simple alarms, notifications, and other
types of simple sound signalization.

decode audio streams independently while performing DSP-related tasks
in parallel. The VS1053B has several key features that make this IC very
popular choice when it comes to audio processing.
By offering high-quality hardware compression (encoding), the VS1053B
allows the audio to be recorded taking up much less space compared to
the same audio information in its raw format. In combination with highquality ADCs and DACs, headphones driver, integrated audio equalizer,
volume control, and more, it represents an all-around solution for any
type of audio application. Along with the powerful graphics processor, the
VS1053B audio processor completely rounds-up the multimedia aspects

6.2 Audio CODEC
Resource-demanding and complex audio processing tasks can be
offloaded from the host MCU by utilizing a dedicated audio CODEC IC,
labeled as VS1053B (1). This IC supports many different audio formats,
commonly found on various digital audio devices. It can encode and
mikromedia 5 for Kinetis CAPACITIVE U S E R M A N U A L
multiplexed with two line-level audio inputs. By using an SMD jumper (5)
located near the headphone jack, it is possible to select which audio input
will be used by the VS1053B. The choices are:
LIN: two line-level inputs form the 1x26 pin header
MIC: electret microphone, connected over the 3.5mm headphone jack
P A G E 25
audio outputs are also available over the 1x26 pin header (4).
7. Sensors and other peripherals
A set of additional onboard sensors and devices adds yet

another layer of usability to the mikromedia 5 development
OTHE R P E RIP HE RALS
board.
7.1 Ambient light sensor
An ambient light sensor (ALS) (1) can be used for dimming the screen
intensity in low-light conditions, allowing for the lower power consumption.
It can also be used to detect the proximity and turn on the screen or
increase its brightness when the user approaches. The ALS sensor on the
mikromedia 7 can be utilized in many ways. The LTR-329ALS-01 sensor
uses the I2C interface to communicate with the host MCU.
P A G E 26
7.2 Digital motion sensor
The FXOS8700CQ, an advanced integrated 3-axis accelerometer and 3-axis
magnetometer, can detect many different motion-related events, including the
orientation event detection, freefall detection, shock detection, as well as tap,
and double-tap event detection. These events can be reported to the host MCU
over two dedicated interrupt pins, while the data transfer is performed over the
I2C communication interface. The FXOS8700CQ sensor can be very useful for
display orientation detection. It can also be used to turn mikromedia 5 into a
complete 6-axis e-compass solution. The I2C slave address can be changed by
using two SMD jumpers grouped under the ADDR SEL label (2).

A high-brightness RGB LED (4) option can be used to provide visual feedback
in a very simple way. There are three pre-biased bipolar transistors on
each of the RGB LED segments (red, blue, and green), allowing them to be
individualy dimmed by PWM pins of the host MCU. Thanks to its reasonably
low power consumption compared to a TFT display, RGB LED can be used
in many situations when only simple visual feedback is required (e.g.
signaling that the application is in the Stand-By mode)
P A G E 27
An infrared (IR) receiver (3) with the integrated PIN diode and a
demodulation section allows simple control over an IR remote controller
to be implemented. Thanks to the integrated demodulation section,
the captured IR signal from the remote controller can be directly used
by the host MCU. The TSOP6238 IR receiver module allows very simple
implementation of the IR remote control option, for any application.

7.5 Temperature sensor
The MCP9700A, an integrated low-power linear active thermistor allows
measurement of the ambient temperature. This sensor provides an analog
voltage which changes linearly with the applied temperature. This voltage
can be sampled by the A/D converter on the host MCU, making it available
for various user applications. The MCP9700A can measure the temperature
within the range from -40°C to +125°C, but the actual measurement range
is limited by the thermal endurance of the mikromedia 5 board itself.
OTHE R P E RIP HE RALS
Nevertheless, having a thermal sensor on board is very useful, allowing the
development of thermal monitoring applications, weather stations, and
similar.
DEVELOPMENT
7.6 Real-time clock (RTC)
OF MULTIMEDIA
The host MCU contains a real-time clock peripheral module (RTC). The
AND GUI-CENTRIC
RTC peripheral uses a separate power supply source, typically a battery. To
allow continuous tracking of time, mikromedia 5 is equipped with a button
P A G E 28
RAPID
cell battery that maintains RTC functionality even if the main power supply
is OFF. Extremely low power consumption of the RTC peripheral allows
these batteries to last very long. The mikromedia 5 development board is
equipped with the button cell battery holder, compatible with the CR1216,
APPLICATIONS
CR1220 and CR1225 button cell battery types, allowing it to include a real
time clock within the applications.
