3.7 J210, J211 RAM Size Configuration
The phyCORE-LPC2292/94 can be populated with three different
RAM memory sizes per shape (U400 thru U403). The size of the
device must be configured to ensure linear addressing of the entire
RAM bank. Jumpers J210 and J211 are used to select the size of the
memory device. The on-board CPLD reads the signal level on the
applicable input pins and configures the individual Chip Select signals
for the RAM devices accordingly.
Note:
Jumpers J210 and J211 are configured at time of delivery of the
phyCORE-LPC2292/94 according to the choosen memory
configuration. Therefor these jumpers must
not be altered by the user!
The following configurations are possible:
RAM Memory Size J210 J211
512 kByte (per shape) open* open*
1 MByte (per shape) closed open
2 MByte (per shape) open closed
Not permitted closed closed
