User's Manual
Introduction
The NCN5150SOICGEVB and NCN5150QFNGEVB
evaluation boards demonstrate the NCN5150 M-BUS
transceiver in SOIC and QFN package respectively. These
evaluation boards include all external components needed
for operating NCN5150 and demonstrate the small PCB
surface area such an implementation requires.
Overview
The NCN5150 is a single-chip integrated slave
transceiver for use in two-wire Meter Bus (M-BUS) slave
devices and repeaters. The transceiver provides all of the
functions needed to satisfy the European Standards EN
13757−2 and EN 1434−3 describing the physical layer
requirements for M-BUS. It includes a programmable
power level of up to 2 (SOIC version) or 6 (NQFP version)
unit loads, which are available for use in external circuits
through a 3.3 V LDO regulator. The NCN5150 can provide
communication up to
communication speed of 38,400 baud (half-duplex).
