The Photon 4-dimensional Digital Information (P4DI) ASIC is a new generation of 2D imaging chips to be connected to
a pixel sensor using the bump and flip chip technologies. It gives in digital format energy, time and position information
for each recorded event. In pixel digitization and storage of the time and amplitude signal are performed. Circuit
solutions for gain and offset variation compensation have been implemented. The ASIC works in sparse data scan mode.
An 8x8 pixels prototype has been manufactured in UMC 0.18um CMOS technology and evaluated
