Abstract
Abstract A system and method for testing an automotive electronic microcontroller includes a multi-chip module comprised of a microcontroller chip and at least one memory chip. This multi-chip module is packaged in the same connection configuration a production single chip microcontroller urgently designed for the controller. The multi-chip module, thus, replaces the single chip module on the controller board itself and provides extra memory. A PC work station may be connected to the controller board via a reserved 8-pin interface. Once development and/or testing is complete, the multi-chip module is then replaced with the single chip module.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
219 words
An Apparatus for adding additional memory to an electronic controller having a printed circuit board designed with at least a first removable microcontrol means having memory available to it for controlling at least one functional system, said first removable microcontrol means being mountable on the printed board by a connection means having a particular configuration, comprising: a module board having a module attachment means for attaching said module board to said connection means, said attachment means having a configuration that corresponds to the particular configuration of the connection means for the first removable microcontrol means; at least a second microcontrol means for controlling at least one functional system, said second microcontrol means being mounted on said module board; and at least one memory means for storing at least digital code and being mounted on said module board, said memory means being available for use by said second microcontrol means and having more memory space than the memory of said first removable microcontrol means, whereby said module board, said second microcontrol means and said memory means form a multi-chip module connectable directly to the connection means for the first removable microcontrol means and providing additional memory to said second microcontrol means so that said second microcontrol means has more memory available than was available to said first removable microcontrol means.
Claim 2
Independent Claim
219 words
An Apparatus for adding additional memory to an electronic controller having a printed circuit board designed with at least a first removable microcontrol means having memory available to it for controlling at least one functional system, said first removable microcontrol means being mountable on the printed board by a connection means having a particular configuration, comprising: a module board having a module attachment means for attaching said module board to said connection means, said attachment means having a configuration that corresponds to the particular configuration of the connection means for the first removable microcontrol means; at least a second microcontrol means for controlling at least one functional system, said second microcontrol means being mounted on said module board; and at least one memory means for storing at least digital code and being mounted on said module board, said memory means being available for use by said second microcontrol means and having more memory space than the memory of said first removable microcontrol means, whereby said module board, said second microcontrol means and said memory means form a multi-chip module connectable directly to the connection means for the first removable microcontrol means and providing additional memory to said second microcontrol means so that said second microcontrol means has more memory available than was available to said first removable microcontrol means.
