4.2 MPC821ADS Evaluation Board Hardware Connections

X31B-G-009-02

The interface was designed using a Motorola MPC821 Application Development

System (ADS). The ADS board has 5 volt logic connected to the data bus, so the

interface included two 74F245 octal buffers on D[0:15] between the ADS and the

S1D13706. In a true 3 volt system, no buffering is necessary.

The following table details the connections between the pins and signals of the MPC821

and the S1D13706.
