S1D13708
Interfacing to the Motorola MPC821 Microprocessor
X39A-G-009-01
Issue Date: 01/11/06
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
S1D13708. In a true 3.3 volt system, no buffering is necessary.
