In order to meet the challenges of EXAFS and XANES spectroscopy of dilute systems, a custom integrated circuit has been fabricated which integrates 32 complete energy resolving photon counting chains onto a 6mm x 4mm chip. This paper reports on initial tests of a 96-element detector implementation using low-leakage diodes fabricated at BNL, and on our plans for a 384-channel version. This large array will initially also use the same diodes but eventually will use a hexagonal drift-detector array. The ASIC is read out through an embedded microcontroller device, and a software package has been written to allow highly automated setup of the entire system and straightforward integration into standard data acquisition packages.
