PCA-6359 Series User's Manual
1.7 System Memory
The top-left edge of the PCA-6359 Series contains three sockets for
168-pin dual inline memory modules (DIMMs). All three sockets use
3.3 V unbuffered synchronous DRAMs (SDRAM). DIMMs are
available in capacities of 16, 32, 64, or 128 MB. The sockets can be
filled in any combination with DIMMs of any size, giving your
PCA-6359 Series single board computer between 16 MB and 256 MB
of memory. Use the following table to calculate the total DRAM
memory within your computer:
Table 1-5: DIMM module allocation table
Socket number 168-pin DIMM memory
1 (16, 32, 64, or 128 MB) x 1
2 (16, 32, 64, or 128 MB) x 1
1.7.1 Sample calculation: DIMM memory capacity
Suppose you install a 128 MB DIMM into your PCA-6359 Series'
socket 1 and a 32 MB DIMM into socket 2. Your total system
memory is 160 MB, calculated as follows:
Table 1-6: DIMM memory capacity sample calculation

2 32 MB x 1 32 MB
Total memory 160 MB
