We present XMM-Newton MOS imaging and PN timing data of
the millisecond pulsar PSR J0218+4232. We confirm the
previously detected pulsations of PSR J0218+4232 and we
show that the folded lightcurve is dependent on energy. We present
the broad band (
keV) spectrum of this millisecond pulsar,
as well as the spectra of: the pulsed emission, the individual
pulses, the interpulse and the non-pulsed region and we compare our
results with previous data from Rosat, BeppoSAX and Chandra. We
discuss the results of the spectral fitting in the context of
recent pulsar models.
