Figure 8. Smartmedia Card Writer Or Flash Drive Application Example
Table 2. SmartMedia Interface Pin Assignment
(1): This line shows if the ST72F65 pin is controlled by the
ST7 core or the DTC.
(2): These lines are not controlled by the DTC but by the
user software running on the ST7 core. The ST72F65 pin
choice is at customer discretion. The pins shown here are
only shown as an example.
(3): When a single card is to be handled, PA7 is free for
other functions. When 2 Smartmedia are to be handled,
pins from both cards should be tied together (i.e. CLE1
with CLE2...) except for the CE pins. CE pin from card 1
should be connected to PA6 and CE pin from card 2
should be connect to PA7. Selection of the operating card
is done by ST7 software.
(4) As this is a single power supply application, the US-
BEN function in not needed. Thus PF4/USBEN pin can be
used as a normal I/O by configuring it as such by the op-
tion byte.
