A smart pixel detector is being developed for time-resolved crystallography for biological and material science applications. Using the pixel detector presented here, the Laue method will enable the study of the evolution of structural changes that occur within a protein as a function of time. The x-ray pixellated detector is assembled to the integrated circuit through a bump bonding process. Within a pixel size of 150{times}150 mm{sup 2}, a low-noise preamplifier-shaper, a discriminator, a 3-bit counter and the readout logic are integrated. The readout, based on the column architecture principle, will accept hit rates above 5{times}10{sup 8}/cm{sup 2}/s with a maximum hit rate per pixel of 1 MHz. This detector will allow time-resolved Laue crystallography to be performed in a frameless operation mode, without dead time. Target specifications, architecture, and preliminary results on a 8{times}8 prototype are presented. {copyright} {ital 1996 American Institute of Physics.}
