In HST Cycle 17, we imaged the well known globular star cluster 47 Tucanaefor 121 orbits using ACS and both the UVIS and IR channels of WFC3 (GO-11677,PI - H. Richer). This unique data set was obtained to address many scientificquestions that demand a very deep, panchromatic, and panoramic view of thecluster's stellar populations. In total, the program obtained over 0.75 Ms ofimaging exposure time with the three HST cameras, over a time span of 9 monthsin 2010. The primary ACS field was imaged in the two broadband filters F606Wand F814W filters, at 13 orientations, for all 121 orbits. The parallel WFC3imaging provides a panchromatic (0.4 - 1.7 micron) and contiguous imaging swathover a 250 degree azimuthal range at impact radii of 6.5 -- 17.9 pc in 47 Tuc.This imaging totals over 60 arcmin^2 in area and utilizes the F390W and F606Wbroadband filters on WFC3/UVIS and the F110W and F160W broadband filters onWFC3/IR.  In this paper, we describe the observational design of the new survey and oneof the methods used to analyze all of the imaging data. This analysis combinesover 700 full-frame images taken with the three HST cameras into a handful ofultra-deep, well-sampled combined images in each of the six filters. Theresults reveal unprecedented color-magnitude diagrams (CMDs) of the clusterextending to >30th magnitude in the optical, 29th magnitude in the UV, and 27thmagnitude in the IR. The data set provides a characterization of the completestellar populations of 47 Tuc, extending from the faintest hydrogen burningdwarfs through the main-sequence and giant branches, down to very cool whitedwarf remnants in the cluster. The imaging also provides the deepest probe ofthe stellar populations of the background Small Magellanic Cloud (SMC) galaxy,resolving low mass main-sequence dwarfs with M < 0.2 Msun.
