6.9. Expansion I/O Connector (J24)

The 96-pin expansion I/O connector J24 is used to connect daughter boards to the main target board. J24 provides
access to many C8051F040 signal pins. Pins for +3 V, digital ground, analog ground and the unregulated power
supply (VUNREG) are also available. The VUNREG pin is connected directly to the unregV pin of the P1
power connector. See Table 7 for a complete list of pins available at J24.

The J24 socket connector is manufactured by Hirose Electronic Co. Ltd, part number PCN13-96S-2.54DS, Digi-
Key part number H7096-ND. The corresponding plug connector is also manufactured by Hirose Electronic Co. Ltd,
part number PCN10-96P-2.54DS, Digi-Key part number H5096-ND.
