Abstract
HKROC, standing for Hyper-Kamiokande Read-Out Chip, is a versatile, auto-triggered and high-performance Application-Specific Integrated Circuit (ASIC) originally designed for the forthcoming multi-purpose Hyper-Kamiokande (HK) Cherenkov-based experiment, that will be operated by $\sim$20 thousand cutting-edge photo-multiplier tubes (PMTs).

In order to cope with the broad physics program of such large-scale experiment, HKROC features an auto-triggered, multi-channel front-end ASIC for the readout of PMT signals, with low power consumption, low dead time, high dynamic range and high accuracy in terms of charge and time reconstruction, making it adaptable to other large Cherenkov-based experiments.

We present below the overall design and performance of the second HKROC prototype received in December 2022.
