A low pin interface module is provided for testing an integrated circuit. The interface module includes an input-output module, a controlling module, a processing module and a storage module specific to the integrated circuit to be tested. The interface module reduces the required number of hardware pins in the integrated circuit for a standalone testing without limiting the integrated circuit testing features. A methodology and a control mechanism achieved with the interface module can be used for the standalone testing of any integrated circuit without using a Joint European Test Action Group test logic interface JTAG implemented following the IEEE Standard 1149.1-1990. The interface module is not limited by a particular debugging platform and allows access to all test features in the integrated circuit with a reduced number of hardware pins and thereby leading to enhanced testing speeds on a tester in parallel and a shorter time-to-a market cycle and a lower development cost.
