Abstract: A method for synchronizing the data interchange in a semiconductor substrate integrated electronic circuit (1) is described, comprising a transmitter block (2) and a receiver block (3) connected through a communication network (4) comprising the steps of:

generating a data signal having a transmission period (T TR ) on a first line (5) that from the transmitter block (2) must be received by the receiver block (3);
generating on a second line (6) a congestion signal from the receiver block (3) to the transmitter block (2) when a congestion event of the receiver block (3) occurs in order to interrupt the data signal transmission,
characterized in that it generates on a third line (7) a synchro signal starting from the transmitter block (2), this synchro signal indicating to the receiver block that the data signal comprises a new datum, and in that the congestion signal interrupts also the synchro signal transmission when a congestion event of the receiver block (3) occurs.
An integrated electronic circuit being integrated on a semiconductor substrate is also described, comprising a transmitter block (2) and a receiver block (3) connected through a communication network (4), the communication network comprising a first line (5) for a data signal, a second line for a congestion signal, and a third line (7) for a synchro signal.
An architecture for manufacturing an integrated electronic circuit being integrated on a semiconductor substrate is also described, comprising a transmitter block (P; 2) and a receiver block (P; 3) connected through a communication network (Q; 4)
