SPI USB Host Controller
Maxim has just introduced a USB Full/Low speed Host Controller with an SPI Interface. It’s the MAX3421E. With this part, it would be possible to add a USB Host Controller to the Zilog eZ80, and use it to connect a USB Flash Drive to the eZ80. Maxim has recently published a Programmer’s Guide for this part, and I am anxiously waiting for them to publish some sample code.
The MAX3421E appears to be a great way to add USB Host (and Device) capability to embedded systems.
