The power supply unit (PSU) provides clean and regulated
power, necessary for proper operation of the mikromedia 5 FPI
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 FPI. It
is equipped with three different power supply inputs, offering
all the flexibility that mikromedia 5 FPI 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.
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.

2.1 Detailed description
POWER SUPPLY
The PSU has a very demanding task of providing power for the host MCU
and all the peripherals onboard, as well as for the externally connected
peripherals. One of the key requirements is to provide enough current,
avoiding the voltage drop at the output. Also, the PSU must be able to
support multiple power sources with diff erent nominal voltages, allowing
switching between them by priority. The PSU design, based on a set of
high-performance power switching ICs produced by Microchip, ensures a
very good quality of the output voltage, high current rating, and reduced
electromagnetic radiation.
At the input stage of the PSU, the MIC2253, a high-effi ciency boost
regulator IC with overvoltage protection ensures that the voltage input at
the next stage is well-regulated and stable. It is used to boost the voltage
of low-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. 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 effi ciency. 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.
The MCP1501, a high-precision buff ered voltage reference from Microchip
is used to provide a very precise voltage reference with no voltage drift. It
can be used for various purposes: the most common uses include voltage
references for A/D converters, D/A converters, and comparator peripherals
on the host MCU. The MCP1501 can provide up to 20mA, limiting its use
exclusively to voltage comparator applications with high input impedance.
Depending on the specifi c application, either 3.3V from the power rail,
or 2.048V from the MCP1501 can be selected. An onboard SMD jumper
labeled as REF SEL off ers two voltage reference choices:
∫ REF: 2.048V from the high-precision voltage reference IC
∫ 3V3: 3.3V from the main power supply rail
2.2 Voltage reference

2.3 PSU connectors
The USB-C connector (labeled as CN8) provides power from the USB host
(typically PC), USB power bank, or USB wall adapter. When powered over the
USB connector, the available power will depend on the source capabilities.
As explained, the advanced design of the PSU allows several types of power
sources to be used, off ering unprecedented fl exibility: when powered
by a Li-Po/Li-Ion battery, it off ers 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 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 adapter, or a battery power bank.
There are three power supply connectors available, each with its unique
purpose:

When using a PC as the power source, the maximum power can be obtained
if the host PC supports the USB 3.2 interface, and is equipped with USB-C
connectors. If the host PC uses the USB 2.0 interface, it will be able to
provide the least power, since only up to 500 mA (2.5W at 5V) is available
in that case. Note that when using longer USB cables or USB cables of low
quality, the voltage may drop outside the rated operating voltage range,
causing unpredictable behavior of the development board.
N O T E If the USB host is not equipped with the USB-C connector, a Type A to
Type C USB adapter may be used (included in the package).
Maximum power ratings, along with the allowed input voltage range in the
case when the USB power supply is used, are given in the table Figure 6:
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.
Maximum power ratings, along with the allowed input voltage range in the
case when the external power supply is used, are given in the table Figure 7:

POWER SUPPLY
When powered by a single-cell Li-Po/Li-Ion battery, mikromedia 5 FPI
off ers an option to be operated remotely. This allows complete autonomy,
allowing it to be used in some very specifi c situations: hazardous
environments, agricultural applications, etc.
The battery connector is a standard 2.5mm pitch XH connector. It allows
a range of single-cell Li-Po and Li-Ion batteries to be used. The PSU of
mikromedia 5 FPI off ers the battery charging functionality, from both the
USB connector and the 12VDC/external power supply. The battery charging
circuitry of the PSU manages the battery charging process, allowing the
optimal charging conditions and longer battery life. The charging process
is indicated by BATT LED indicator, located on the back of mikromedia 5 FPI.
The PSU module also includes the battery charger circuit. Depending
on the operational status of the mikromedia 5 FPI development board,
the charging current can be either set to 100mA or 500mA. When the
development board is powered OFF, the charger IC will allocate all available
power for the battery charging purpose. This results in faster charging, with
the charging current set to approximately 500mA. While powered ON, the
available charging current will be set to approximately 100 mA, reducing
the overall power consumption to a reasonable level.

N O T E Using low-quality USB hubs, and too long or low-quality USB cables,
may cause a signifi cant USB voltage drop, which can obstruct the
battery charging process.

2.4 Power redundancy and
uninterrupted power supply (UPS)
2.5 Powering up the
mikromedia 5 FPI board
The PSU module supports power supply redundancy: it will automatically
switch to the most appropriate power source if one of the power sources
fails or becomes disconnected. The power supply redundancy also allows
for an uninterrupted operation (i.e. UPS functionality, the battery will still
provide power if the USB cable is removed, without resetting mikromedia 5
FPI during the transition period).
After a valid power supply source is connected (1) in our case with a single-
cell Li-Po/Li-Ion battery, mikromedia 5 FPI 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 FPI is powered ON.

5. Connectivity
mikromedia 5 FPI off ers a huge number of connectivity
options. It includes support for the WiFi, RF and USB
(HOST/DEVICE). Besides those options, it also off ers
three standardized mikroBUS™ Shuttle connectors. It is a
considerable upgrade for the system, as it allows interfacing
with the huge base of Click boards™.
5.1 USB
The host MCU is equipped with the USB peripheral module, allowing
simple USB connectivity. USB (Universal Serial Bus) is a very popular
industry standard that defi nes cables, connectors, and protocols used
for communication and power supply between computers and other
devices. mikromedia 5 FPI supports USB as HOST/DEVICE modes, allowing
the development of a wide range of various USB-based applications. It
is equipped with the USB-C connector, which off ers many advantages,
compared to earlier types of USB connectors (symmetrical design, higher
current rating, compact size, etc).
The USB mode selection is done using a monolithic controller IC. This IC
provides Confi guration Channel (CC) detection and indication functions.
To set up mikromedia 5 FPI as the USB HOST, the USB PSW pin should be set to
a LOW logic level (0) by the MCU. If set to a HIGH logic level (1), mikromedia 5 FPI
acts as a DEVICE. While in HOST mode, mikromedia 5 FPI provides power
over the USB-C connector (1) for the attached DEVICE. The USB PSW pin
is driven by the host MCU, allowing the software to control the USB mode.
The USB ID pin is used to detect the type of the device attached to the USB
port, according to the USB OTG specifi cations: the USB ID pin connected to
GND indicates a HOST device, while the USB ID pin set to a high impedance
state (HI-Z) indicates that the connected peripheral is a DEVICE.

CONNECTIVITY
P A G E 19
mikromedia 5 for Kinetis CAPACITIVE FPI U S E R M A N U A L

5.2 RF
mikromedia 5 FPI 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 FPI uses the nRF24L01+ (1), a single-chip 2.4GHz
transceiver 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
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 FPI also
features a small chip antenna (4) as well as SMA connector for external
antenna.
