Specifications of MSC8156ADS

• Contents: Board
• Leaded Process Compatible: Yes
• Rohs Compliant: Yes
• Peak Reflow Compatible (260 C): Yes
• For Use With/related Products: MSC8156
• Lead Free Status / RoHS Status: Lead free / RoHS Compliant

The FPGA supports all the MSC8156 hardware configuration modes:
When RCW = ‘001’ or ‘010’, the configuration word originates from either the small or big I
EEPROM. The FPGA selects the suitable part as per the RCW value.

The whole 64-bit configuration word sampled
previously from the DIP-switches is driven by FPGA
in four cycles by 16- bit each time. The MSC8156
RCW_LSEL[3–0] output selects the appropriate
configuration bits subset.
The small EEPROM applies address 0x50 to provide
configuration data. Configuration DIP-switches
don’t care.
The big EEPROM applies address 0x50 to provide
configuration data. Configuration DIP-switches
don’t care.
At first the FPGA samples 22 appropriate
DIP-switches. At the second time interval the data is
driven to the MSC8156.
Only RCW_SRC three bits are driven the rest
configuration DIP-switches don’t care.
