A single-chip transceiver integrated circuit (100) has multiple on-chip circuits that implement receiver functions, transmitter functions, and audio processing functions. The IC (100) has interfaces (220, 240, 252, 270, 260, 245, 288, 290) which are situated among the on-chip circuits, and which couple one on-chip circuit to another. At least some of these on-chip interfaces (220, 240, 245, 252, 270) are configurable to couple an off-chip processing circuit to substitute for a corresponding on-chip circuit. In the preferred embodiment, the single-chip transceiver IC (100) supports radio configurations having off-chip versions of corresponding on-chip circuits for performing receiver front-end functions, synthesizer functions, reference oscillator functions, and audio processing functions.
