MAX3421E

The MAX3421E allows a USB Host and/or device to be attached to any Microcontrller which is capable of providing an SPI interface.

HCC-Embedded have a reference design for this device based in the LPC2292. Only the simple SPI driver needs to be ported to support other microcontrollers.

HCC have ported their USB Device stack to this device and also provide a USB Host Controller for this device fully compatible with all HCC Host Class Drivers.

3421 SD Module

HCC have available a SD card socket compatible module for the MAX3421E. Simply plug it into any SD card socket and communicate through the SPI interface. it can be used with any of HCC's uCDrive Dev boards or indeed any develoment board with an SD card socket which is SPI capable.

HCC's USB host and USB device stacks can be run from almost any microcontroller using tis module.

It has a mini USB connector which allows either a USB host system or a USB device to be connected. Typical aplications include accessing a standard flash drive (host mode) or connecting a virtual serial port on the target which appears as a standard COM port on the host PC..
