We present a two-day long RXTE observation and simultaneous Swift data of the bright X-ray transient XTE J1752-223 .
Spectral and timing properties were stable during the observation .
The energy spectrum is well described by a broken power-law with a high energy cut-off .
A cold disc ( \sim 0.3 keV ) is observed when Swift/XRT data are considered .
The fractional rms amplitude of the aperiodic variability ( 0.002–128 Hz ) is 48.2 \pm 0.1 \% and it is not energy dependent .
The continuum of the power density spectrum can be fitted by using four broad-band Lorentzians .
A high frequency ( \sim 21 Hz ) component and two weak QPO-like features are also present .
Time-lags between soft and hard X-rays roughly follow the relation \Delta t \propto \nu ^ { -0.7 } , with delays dropping from \sim 0.5 ( 0.003 Hz ) to \sim 0.0015 ( \geq 10 Hz ) seconds .
Our results are consistent with XTE J1752-223 being a black-hole candidate , with all timing and spectral components very similar to those of Cyg X-1 during its canonical hard state .
