Microelectronic technologies made possible the implementation of solid state based metering systems. In this paper, an ASIC design that implements all but the analog pari of a watt-hour meter is described. This A -SIC designed with the A P B B I ] technology is intented ter in a hybrid telecounting system or in a fully static watt-hour meter. In the first case, the data received and processed by the A S I C i s the disk t u m count of the F e m r i s power meter, being the transmission from the latter t o the ASIC achieved by optical interconnection. In the second case, a fully static power meter is used, and, data received by fhe A S I C are two 1.2 bit WO& representing the current and the voltage values.to be used in conjunction wit d the Ferraris power me-1
