S1D13505 Interfacing to the Motorola MPC821 Microprocessor
X23A-G-008-05 Issue Date: 01/02/05
Table 4-1:,“List of Connections from MPC821ADS to S1D13505” on page 16 shows the
connections between the pins and signals of the MPC821 and the S1D13505.
Note
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
S1D13505. In a true 3 volt system, no buffering is necessary.
4.2 Hardware Connections
The following table details the connections between the pins and signals of the MPC821
and the S1D13505.
