The IceCube Neutrino Observatory consists of a cubic-kilometer in-ice neutrino detector and the IceTop surface detector. IceTop comprises 81 pairs of ice-Cherenkov tanks for air-shower detection. As part of the upgrades, IceTop will be equipped with new surface stations, each consisting of eight scintillator panels and three radio antennas. Three of these stations are already in operation at the South Pole, and more are to be installed in the coming years in the area of the current IceCube experiment. The design is also the baseline for the surface instrumentation of IceCube-Gen2.

In this contribution, we focus on improvements to the current readout electronics deployed in prototype stations at IceCube, Pierre Auger, and the Telescope Array. Additionally, we present the development status of a new generation of the electronics capable of being implemented in the future IceCube and IceCube-Gen2 readout system. This design is based on a multi-FPGA board and provides GSa/s radio readout capabilities along with extensive onboard memory for signal buffering.
