I just took delivery on a batch of MAX3421Es from Maxim. They are available for sale in the store for $8.00.
The MAX3421E makes the vast collection of USB peripherals available to any microprocessor, ASIC, or DSP when it operates as a USB host. For point-to-point solutions, for example, a USB keyboard or mouse interfaced to an embedded system, the firmware that operates the MAX3421E can be simple since only a targeted device is supported.
This controller is supported by open source firmware that I’m developing for 8-bit microcontrollers, including PIC18s and Arduino.

Hi,
I just went on maxim web site and they say the MAX3421E is not for new design. Are you aware on any replacement for it?

I haven’t heard about any replacements.
