The Chandra ACIS Survey of M33 (ChASeM33) is the deepest X-ray survey to date of M33. ChASeM33 covers about 70% of the D25 isophote (R 4.0 kpc) with a total exposure of 1.4 Ms. The source catalog includes 662 sources, reaching a limiting sensitivity of 2.0e34 erg/s in the 0.35--8.0 keV energy band. There are fifteen sources in the catalog with more than 2,000 net counts, allowing detailed spectral and timing analyses to be conducted. We report here the results of fitting these spectra with multi-component disk blackbody, power-law, and/or thermal plasma models. We also report on the short-term (within an observation) and long-term (from one observation to another) variability of these sources. These X-ray spectral and timing results in conjunction with optical spectroscopy for some of the sources, allow us to classify the objects. Six of the sources are X-ray Binaries (3 certain/3 most likely), 3 are Supernova Remnants (all three certain), and 6 are Active Galactic Nuclei (3 certain/3 most likely). The faintest of these sources has a flux (0.35-8.0 keV) of 3.5e-14 ergs/(s cm2) and an inferred luminosity of 3.0e36 ergs/s (0.35-8.0 keV) at the distance of M33. We comment on the contribution of these ``background'' sources to studies of the X-ray source populations in galaxies.
