PNEV5190B evaluation board quick start guide
3 Hardware
The PNEV5190B V1.0, as shown in
, provides some test functions which might
not be used for the typical hardware and software evaluation. The PNEV5190M (module)
can be used as a simple standard reader module without modification. In addition, it can
be used to define and optimize the analog settings for any connected antenna or it can
be used to develop and modify any RFID and NFC application based on the NFC Reader
Library.
3.1 Hardware introduction
The PN5190 is supplied with a supply voltage, which can be chosen between internal
and external supply. For the internal supply either 5 V, 3.3 V or 1.8 V (for VDDIO) can
be used. The external power supply must be between 5 V and 12 V DC (polarity does
not matter) since the board provides a rectifier and LDO to supply the circuit with 6 V
(optional, supply voltage ≥7.5 V), 5 V, 3.3 V and 1.8 V.
Warning: The PN5190 in default configuration requires an external power supply, i.e. the
USB supply does not provide enough current.
The PN5190 is connected to a Kinetis K82 121BGA µC via SPI. A specific firmware on
the K82 allows using the PNEV5190B together with the NFC Cockpit.
The connection to the PC is done via USB micro connection.
Another connection option allows connecting a Linker / LPC-LINK2 board to the
PNEV5190B with a debug cable. This allows the development of custom software or the
execution of the NXP NFC Reader Library code including samples.
In case a different host microcontroller shall be used, the SPI interface is available for
connection to an external host (the onboard K82 is not used in this case).
