AN1886 - APPLICATION NOTE
36/54
CONCLUSION
This application note discusses important issues in USB design using μPSD32xxA, and describes all the
currently known issues. It shows how to design USB applications with μPSD32xxA, and which steps and
rules must be met to avoid possible issues.
The USB block in the μPSD32xxA is very simple, and is typically used in keyboards, mouse and other
simple devices. The latest version of these drivers reduces the possible issues to a minimum, but many
conditions must be applied when programming the USB application.
In case there is a possibility of changing the driver at the host, or to use a non-standard driver, it is recom-
mended to use the latest version of the USB drivers in the μPSD32xxA, but to disable:
all of the new features
–
including Enhanced Host Controller specification features, EHCI
other modifications, especially those aimed at reaching higher throughput of USB bus
–
thereby still leaving the system capable of reaching the same traffic on the USB as with old
USB1.1 controllers connected to low-speed devices
