We present a scheme to upgrade the CMS HCAL front-end electronics in 2015-16. The HCAL upgrade is required to handle a major luminosity increase of LHC which is expected for 2017. This paper focuses on the requirements for the new electronics and on the proposed solutions. The requirements include increased channel count, additional timing capabilities, and additional redundancy in a harsh environment which is constrained by the existing system. The proposed solutions span from chip level to system level. They include the development of a new ADC ASIC, the evaluation and use of circuits from other developments, evaluation of commercial FPGAs, better thermal design and improvements in the overall architecture.
