The JP5 strap enables connection of an ammeter to measure the AT91M42800A global
consumption (V
(JP8 in 3V3 position). Core consumption can be measured by connecting another
ammeter between JP8 1 - 2 or 2 - 3, depending on the power supply used to power the
core.
The JP6 strap allows the user to connect the electrical and mechanical grounds.
The AT91EB42 Evaluation Board is supplied with two 128K x 8 SRAM memories. If,
however, the user needs more than 256K bytes of memory, the devices can be replaced
with two 512K x 8 3.3V 10/15 ns SRAMs, giving a total of 1024K bytes. The following
references for the 512K x 8 SRAM are available.
