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.
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.
