PSB 7238
Electrical Specification
7.7.5
External Memory Interface
No external SRAM needs to be connected to the JADE, since it has all memories on chip.
Nevertheless, an external memory interface is implemented for development purpose
only.
The timing of this interface is not part of the test procedure for the JADE, and so not
specified at this point. For development purpose especially tested devices (including
external memory interface test) are available from Siemens on request in small
quantities. These devices are working under special conditions such as e.g. higher
supply voltage.
