The SPIROC chip is a dedicated very front-end electronics to read out a prototype of the Analog Hadronic Calorimeter equipped with Silicon Photomultiplier (SiPM) for ILC (International Linear Collider). A first prototype of SPIROC has been fabricated in 2007 and a second version in 2010. Many test bench and test beam measurements have been performed showing a good overall behaviour. However some limitations have been encountered. Another version has been submitted in February 2012 to correct these limitations and to improve the ASIC performances. After an exhaustive description of the ASIC, the performances will be presented in this paper.
