2. Physical <strong>Interface</strong> 2.1. TSOP-48 and WSOP-48 Pin Assignments Figure 2 defines the pin assignments for devices using 48-pin TSOP or 48-pin WSOP packaging for 8-bit data access. Figure 3 defines the pin assignments for devices using 48-pin TSOP or 48-pin WSOP packaging for 16-bit data access. The package with 16-bit data access does not support the source synchronous data interface. The physical dimensions of the TSOP package is defined in the JEDEC document MO-142 variation DD. The physical dimensions of the WSOP package is defined in the JEDEC document MO-259. 7
