NCN5100 Arduinot Shield
Evaluation Board
User's Manual
EVBUM2715/D
INTRODUCTION
KNX [3] is a popular open home and building automation standard
ON Semiconductor has a series of transceivers that handle the low
level communication.
The NCN5100ASGEVB evaluation boards are Arduino-compatible
shields enabling rapid prototyping with a microcontroller of choice.
All external components necessary for operating the transceivers are
present on the shield. Plug it in a Arduino-compatible development kit
and start developing!
FEATURES
Arduino Uno V3 compatible connectors
Compatible with a wide variety of microcontroller development
boards
Four on-board buttons/LEDs to build a dimmer application
Available in UART- and SPI-version
Fully KNX-compliant transceiver
Easily get started with KNX
Maximum bus current up to 40 mA
Two high-efficiency DC-DC converters
3.3 V fixed output
1.2 V to 21 V variable output
Integrated 20 V linear regulator output
OVERVIEW
The NCN5100ASGEVB boards come in three variants containing
the NCN5110, NCN5121 and NCN5130 transceivers. The NCN5110
is a bit transceiver and all the timings are handled by the
microcontroller. Both the NCN5121 and NCN5130 also implement
the MAC layer, reducing the software development effort. All critical
timings are handled by the transceiver.
All transceivers include two high-effciency DC-DC converters. One
fixed converter generating 3.3 V, supplies the transceiver and other
optional peripherals such as a microcontroller. The second DC-DC
converter has an adjustable output voltage ranging from 1.2 V to 21 V
and can be used to supply peripherals such as, relays, a display, etc. ...
The Arduino shield form factor makes it easy to start developing;
just plug the shield into a compatible microcontroller board and start
coding. Thanks to the on-board buttons and LEDs, it is not necessary
to plug in additional shields to start testing. A simple dimmer
application can be set-up in no time with only the KNX
Arduino-shield.
